JON GRUBER: Education
economics-- so

00:00:11.880 --> 00:00:12.920 align:middle line:90%
let's remind ourselves.

00:00:12.920 --> 00:00:16.480 align:middle line:84%
We showed last time
that basically, it

00:00:16.480 --> 00:00:17.920 align:middle line:84%
doesn't look like
across countries

00:00:17.920 --> 00:00:21.440 align:middle line:84%
what you spend on education
really correlates with outcomes.

00:00:21.440 --> 00:00:23.282 align:middle line:84%
We then ask the question,
well, why should--

00:00:23.282 --> 00:00:24.740 align:middle line:84%
this is what the
government spends?

00:00:24.740 --> 00:00:25.360 align:middle line:90%
I'm sorry.

00:00:25.360 --> 00:00:27.193 align:middle line:84%
We then ask, well, why
should the government

00:00:27.193 --> 00:00:28.280 align:middle line:90%
be involved in education?

00:00:28.280 --> 00:00:30.160 align:middle line:84%
Why not just have a private
market where everyone just

00:00:30.160 --> 00:00:32.410 align:middle line:84%
pays for it themselves and
take loans if they need to?

00:00:32.410 --> 00:00:35.760 align:middle line:84%
And we came up with
a number of answers

00:00:35.760 --> 00:00:39.280 align:middle line:84%
from the fact there's minimum
standards of citizenship we want

00:00:39.280 --> 00:00:41.760 align:middle line:84%
to meet, to improvements
in productivity

00:00:41.760 --> 00:00:48.143 align:middle line:84%
that spill over to others,
to credit market failures.

00:00:48.143 --> 00:00:49.560 align:middle line:84%
And I think an
important one here,

00:00:49.560 --> 00:00:51.960 align:middle line:84%
is this failure to
maximize family utility.

00:00:51.960 --> 00:00:56.600 align:middle line:84%
Let's remember that
it's kids who ultimately

00:00:56.600 --> 00:00:59.260 align:middle line:84%
bear the consequences of their
parents' decisions to educate

00:00:59.260 --> 00:01:01.200 align:middle line:90%
them in important ways.

00:01:01.200 --> 00:01:04.660 align:middle line:84%
Income mobility is a critical
aspect of success in life.

00:01:04.660 --> 00:01:07.540 align:middle line:84%
And income mobility depends
critically on education.

00:01:07.540 --> 00:01:10.347 align:middle line:84%
So only if we really
think parents are really

00:01:10.347 --> 00:01:12.180 align:middle line:84%
doing what's in society's
best interest, not

00:01:12.180 --> 00:01:14.140 align:middle line:84%
just their own best
interest, do we really

00:01:14.140 --> 00:01:16.460 align:middle line:84%
want to leave a total in
the hands of families about

00:01:16.460 --> 00:01:18.080 align:middle line:84%
whether kids go
to school or not?

00:01:18.080 --> 00:01:19.980 align:middle line:84%
We probably want some
government involvement

00:01:19.980 --> 00:01:22.020 align:middle line:90%
in thinking about that at least.

00:01:22.020 --> 00:01:24.598 align:middle line:84%
OK, so now, with that
as background, now

00:01:24.598 --> 00:01:27.140 align:middle line:84%
that we've answered the first
question-- which is when should

00:01:27.140 --> 00:01:28.182 align:middle line:90%
the government intervene?

00:01:28.182 --> 00:01:31.478 align:middle line:84%
The answer is generally it
should in cases like education.

00:01:31.478 --> 00:01:33.020 align:middle line:84%
We come to the second
question, which

00:01:33.020 --> 00:01:35.395 align:middle line:84%
is how should the
government intervene?

00:01:35.395 --> 00:01:37.020 align:middle line:84%
And here we're going
to start with what

00:01:37.020 --> 00:01:39.780 align:middle line:84%
the government actually
does, and then think about

00:01:39.780 --> 00:01:41.500 align:middle line:90%
whether it makes sense.

00:01:41.500 --> 00:01:43.500 align:middle line:90%
So what does the government do?

00:01:43.500 --> 00:01:45.140 align:middle line:84%
Well, the government,
in practice,

00:01:45.140 --> 00:01:49.700 align:middle line:84%
provides free public
education of a certain amount.

00:01:49.700 --> 00:01:55.140 align:middle line:84%
To understand how that works,
let's think about a simple model

00:01:55.140 --> 00:01:59.600 align:middle line:84%
where individuals, much
like our model of grants

00:01:59.600 --> 00:02:01.520 align:middle line:84%
at the end of the last
chapter, but now it's

00:02:01.520 --> 00:02:03.300 align:middle line:90%
an individual making a decision.

00:02:03.300 --> 00:02:05.792 align:middle line:84%
They're deciding between how
much to spend on education

00:02:05.792 --> 00:02:07.500 align:middle line:84%
and how much to spend
on everything else.

00:02:07.500 --> 00:02:11.152 align:middle line:84%
So this is the figure
11-2 in your handout.

00:02:11.152 --> 00:02:13.360 align:middle line:84%
The government's deciding
how much spend in education

00:02:13.360 --> 00:02:15.110 align:middle line:84%
and how much to spend
on everything else--

00:02:15.110 --> 00:02:16.360 align:middle line:90%
the individual, I'm sorry.

00:02:16.360 --> 00:02:18.200 align:middle line:84%
And they face a
budget constraint.

00:02:18.200 --> 00:02:20.080 align:middle line:84%
They can either
spend an amount--

00:02:20.080 --> 00:02:21.180 align:middle line:90%
they have a budget.

00:02:21.180 --> 00:02:23.720 align:middle line:84%
They can either spend it all
in education, in which case

00:02:23.720 --> 00:02:26.800 align:middle line:84%
they'll get B of
amount of education,

00:02:26.800 --> 00:02:30.720 align:middle line:84%
or all the other goods, in
which case they'll get G2.

00:02:30.720 --> 00:02:34.400 align:middle line:84%
And let's assume, despite
the cross-country graph

00:02:34.400 --> 00:02:36.880 align:middle line:84%
we saw a few minutes ago,
that education spending

00:02:36.880 --> 00:02:37.857 align:middle line:90%
is productive.

00:02:37.857 --> 00:02:39.940 align:middle line:84%
Let's assume that the more
you spend in education,

00:02:39.940 --> 00:02:41.872 align:middle line:84%
the better education
your kid gets.

00:02:41.872 --> 00:02:43.580 align:middle line:84%
We're just going to
make that assumption.

00:02:43.580 --> 00:02:45.330 align:middle line:84%
We'll come back later
to evidence on that.

00:02:45.330 --> 00:02:46.520 align:middle line:90%
Let's assume that here.

00:02:46.520 --> 00:02:50.720 align:middle line:84%
So the x-axis is both
spending and quality

00:02:50.720 --> 00:02:52.680 align:middle line:84%
So parents have to
make some decision.

00:02:52.680 --> 00:02:54.482 align:middle line:84%
And absent government
intervention,

00:02:54.482 --> 00:02:56.940 align:middle line:84%
they'll make some decisions
with three illustrative parents

00:02:56.940 --> 00:02:57.440 align:middle line:90%
here--

00:02:57.440 --> 00:03:01.060 align:middle line:84%
X, Y, and Z. They choose
different tradeoffs absent

00:03:01.060 --> 00:03:02.780 align:middle line:90%
government intervention.

00:03:02.780 --> 00:03:05.820 align:middle line:84%
So the ex-ante, we end up
with three different education

00:03:05.820 --> 00:03:06.940 align:middle line:90%
levels--

00:03:06.940 --> 00:03:11.378 align:middle line:84%
E1, E2, and E3 for
three different parents.

00:03:11.378 --> 00:03:12.920 align:middle line:84%
Now the government
comes in and says,

00:03:12.920 --> 00:03:15.820 align:middle line:84%
we're going to provide
free public education up

00:03:15.820 --> 00:03:23.460 align:middle line:84%
to an amount E sub F. So anybody
can have E sub F for free.

00:03:23.460 --> 00:03:26.220 align:middle line:84%
But we're going to make
a key assumption here.

00:03:26.220 --> 00:03:29.860 align:middle line:84%
If you go to public school,
there's no supplementation.

00:03:29.860 --> 00:03:30.920 align:middle line:90%
There's no tutoring.

00:03:30.920 --> 00:03:34.820 align:middle line:84%
There's no, like, extra
Russian math school

00:03:34.820 --> 00:03:35.903 align:middle line:90%
you can send your kids to.

00:03:35.903 --> 00:03:38.570 align:middle line:84%
It's a world where basically, if
you go to public school, that's

00:03:38.570 --> 00:03:39.420 align:middle line:90%
all you get.

00:03:39.420 --> 00:03:41.500 align:middle line:84%
So your choice is either
you go to public school

00:03:41.500 --> 00:03:42.667 align:middle line:90%
or you go to private school.

00:03:42.667 --> 00:03:45.620 align:middle line:84%
If you go to public school,
you get E sub F for free,

00:03:45.620 --> 00:03:47.260 align:middle line:90%
but no more.

00:03:47.260 --> 00:03:51.563 align:middle line:84%
If you go to private school,
you still get what you pay for.

00:03:51.563 --> 00:03:53.480 align:middle line:84%
So how does this change
the budget constraint?

00:03:53.480 --> 00:03:55.470 align:middle line:84%
Well, the new budget
constraint, much

00:03:55.470 --> 00:03:57.490 align:middle line:84%
like we saw with the
grant example last time,

00:03:57.490 --> 00:04:01.790 align:middle line:84%
is a flat segment that goes all
the way to an amount E sub F,

00:04:01.790 --> 00:04:04.190 align:middle line:84%
all the way up to
point C, because you

00:04:04.190 --> 00:04:05.910 align:middle line:84%
can get that much
education for free

00:04:05.910 --> 00:04:08.830 align:middle line:84%
without giving up any
other private goods.

00:04:08.830 --> 00:04:11.650 align:middle line:84%
At that point, you stop
getting free public education.

00:04:11.650 --> 00:04:13.910 align:middle line:84%
The budget constraint
drops from C to D.

00:04:13.910 --> 00:04:17.910 align:middle line:84%
And you return to the original
private budget constraint.

00:04:17.910 --> 00:04:23.590 align:middle line:84%
Student budget constraint
goes G2, C, D, B.

00:04:23.590 --> 00:04:26.230 align:middle line:84%
That's the new
budget constraint.

00:04:26.230 --> 00:04:28.910 align:middle line:90%
Questions about that?

00:04:28.910 --> 00:04:31.470 align:middle line:84%
Now let's ask, how does that
affect people's choices?

00:04:31.470 --> 00:04:37.390 align:middle line:84%
Well, let's start with
person X. Person X

00:04:37.390 --> 00:04:39.710 align:middle line:84%
used to not want
a lot of education

00:04:39.710 --> 00:04:41.130 align:middle line:90%
and a lot of private goods.

00:04:41.130 --> 00:04:43.427 align:middle line:90%
Now they can get more of both.

00:04:43.427 --> 00:04:45.510 align:middle line:84%
They can get a lot more
education and more private

00:04:45.510 --> 00:04:49.150 align:middle line:84%
goods by dropping out of
their crappy private school

00:04:49.150 --> 00:04:51.510 align:middle line:90%
and joining this public school.

00:04:51.510 --> 00:04:53.890 align:middle line:90%
So person X, it's a no-brainer.

00:04:53.890 --> 00:04:57.010 align:middle line:84%
They've made themselves
unambiguously better off.

00:04:57.010 --> 00:05:01.290 align:middle line:90%
For person Z, nothing's changed.

00:05:01.290 --> 00:05:04.890 align:middle line:84%
The public schooling
level is so much lower

00:05:04.890 --> 00:05:06.930 align:middle line:84%
than their desired
level of education

00:05:06.930 --> 00:05:09.850 align:middle line:90%
that they're not interested.

00:05:09.850 --> 00:05:11.550 align:middle line:84%
Person Y is the
interesting case.

00:05:11.550 --> 00:05:13.850 align:middle line:84%
And what is particularly
notable about person Y?

00:05:13.850 --> 00:05:19.130 align:middle line:84%
What's notable about person
Y is that their indifference

00:05:19.130 --> 00:05:21.650 align:middle line:84%
curve that's tangent to
the original private budget

00:05:21.650 --> 00:05:27.090 align:middle line:84%
constraint passes through the
vertical segment from C to D.

00:05:27.090 --> 00:05:27.950 align:middle line:90%
What does that mean?

00:05:27.950 --> 00:05:32.090 align:middle line:84%
That means that graphically,
they are better off at point C

00:05:32.090 --> 00:05:34.330 align:middle line:84%
than they are at
their current choice.

00:05:34.330 --> 00:05:37.810 align:middle line:84%
So they will move from their
current choice of E sub 2

00:05:37.810 --> 00:05:38.510 align:middle line:90%
to E sub F.

00:05:38.510 --> 00:05:39.510 align:middle line:90%
And how do we know that?

00:05:39.510 --> 00:05:41.710 align:middle line:84%
You can just prove
geometrically that since there's

00:05:41.710 --> 00:05:44.650 align:middle line:84%
a difference across that
vertical segment, at point C,

00:05:44.650 --> 00:05:47.210 align:middle line:84%
they'll be in a higher
indifference curve.

00:05:47.210 --> 00:05:52.310 align:middle line:84%
In other words, person y is
willing to get less education

00:05:52.310 --> 00:05:56.430 align:middle line:84%
to get a lot more
other consumption.

00:05:56.430 --> 00:06:02.750 align:middle line:84%
This is a case of more
than 100% crowd out.

00:06:02.750 --> 00:06:07.190 align:middle line:84%
This is a case where basically,
the government providing it

00:06:07.190 --> 00:06:10.415 align:middle line:84%
doesn't just reduce
private provision to 0.

00:06:10.415 --> 00:06:12.790 align:middle line:84%
It produces private provision
by more than the government

00:06:12.790 --> 00:06:15.030 align:middle line:90%
actually provided.

00:06:15.030 --> 00:06:21.070 align:middle line:84%
That is total educational
attainment for person y falls.

00:06:21.070 --> 00:06:24.270 align:middle line:84%
So on net, what
happens to society?

00:06:24.270 --> 00:06:25.790 align:middle line:84%
Well that depends
on the proportions

00:06:25.790 --> 00:06:30.430 align:middle line:84%
of people who are X, Y, and
Z. If society's all like X,

00:06:30.430 --> 00:06:32.750 align:middle line:84%
education unambiguously
increases.

00:06:32.750 --> 00:06:35.030 align:middle line:84%
If society is all like Z,
education unambiguously

00:06:35.030 --> 00:06:36.110 align:middle line:90%
doesn't change.

00:06:36.110 --> 00:06:39.350 align:middle line:84%
But if it's like Y,
education can actually fall.

00:06:39.350 --> 00:06:42.810 align:middle line:84%
This is a key point made
by Sam Peltzman in 1973.

00:06:42.810 --> 00:06:45.510 align:middle line:84%
It's a famous model--
another Chicago economist,

00:06:45.510 --> 00:06:47.650 align:middle line:84%
showing that the government
can make things worse,

00:06:47.650 --> 00:06:51.250 align:middle line:84%
and that in principle,
free public education can

00:06:51.250 --> 00:06:52.510 align:middle line:90%
lower educational attainment.

00:06:52.510 --> 00:06:53.802 align:middle line:90%
It's a pretty striking finding.

00:06:53.802 --> 00:06:55.692 align:middle line:84%
But it's pretty
clear from this graph

00:06:55.692 --> 00:06:57.650 align:middle line:84%
that a free public
education can actually lower

00:06:57.650 --> 00:06:59.155 align:middle line:90%
how much education people get.

00:06:59.155 --> 00:07:00.530 align:middle line:84%
And whether it
will happen or not

00:07:00.530 --> 00:07:04.770 align:middle line:84%
depends on how big Y is
compared to X, basically.

00:07:04.770 --> 00:07:07.270 align:middle line:84%
X is getting a lot more, y
is getting somewhat less.

00:07:07.270 --> 00:07:09.170 align:middle line:84%
The size of those
groups will determine

00:07:09.170 --> 00:07:12.490 align:middle line:84%
whether total education
goes up or not.

00:07:12.490 --> 00:07:15.250 align:middle line:84%
So this is really a
quite striking finding,

00:07:15.250 --> 00:07:18.050 align:middle line:84%
that free public education
could actually lead

00:07:18.050 --> 00:07:21.050 align:middle line:90%
to less educational attainment.

00:07:21.050 --> 00:07:23.930 align:middle line:84%
Now, Peltzman
said, look, there's

00:07:23.930 --> 00:07:27.130 align:middle line:84%
an easy solution to
this problem, which

00:07:27.130 --> 00:07:30.050 align:middle line:84%
is what if instead
of telling people

00:07:30.050 --> 00:07:34.570 align:middle line:84%
they have to go to public
school, we gave them a voucher?

00:07:34.570 --> 00:07:39.090 align:middle line:84%
And that voucher was
for the amount E sub F.

00:07:39.090 --> 00:07:42.010 align:middle line:84%
And we said, look, there
will be public schools

00:07:42.010 --> 00:07:43.153 align:middle line:90%
that will provide E sub F.

00:07:43.153 --> 00:07:45.070 align:middle line:84%
But if you don't want
to go to public schools,

00:07:45.070 --> 00:07:46.970 align:middle line:84%
you can take your
voucher E sub F

00:07:46.970 --> 00:07:49.830 align:middle line:84%
and apply it to any
private school as well.

00:07:49.830 --> 00:07:51.928 align:middle line:84%
So we're going to give
you a piece of paper.

00:07:51.928 --> 00:07:53.470 align:middle line:84%
You can just turn
that piece of paper

00:07:53.470 --> 00:07:55.250 align:middle line:84%
back into the public
school and be done with it.

00:07:55.250 --> 00:07:57.375 align:middle line:84%
You turn that piece of
paper into a private school,

00:07:57.375 --> 00:07:59.510 align:middle line:84%
and then pay some
extra on top of that

00:07:59.510 --> 00:08:00.690 align:middle line:90%
and go to private school.

00:08:00.690 --> 00:08:05.630 align:middle line:84%
So this is a coupon off of
private school for the amount

00:08:05.630 --> 00:08:07.790 align:middle line:90%
that we spend on public school.

00:08:07.790 --> 00:08:10.630 align:middle line:84%
What would that do to
the budget constraint?

00:08:10.630 --> 00:08:13.350 align:middle line:84%
Well, that moves the budget
constraint to something like

00:08:13.350 --> 00:08:20.150 align:middle line:84%
figure 11-3, where now there's
still the same flat segment

00:08:20.150 --> 00:08:20.990 align:middle line:90%
along the top.

00:08:20.990 --> 00:08:23.490 align:middle line:84%
But now below that, the whole
budget constraint shifted out.

00:08:23.490 --> 00:08:25.910 align:middle line:84%
This is like the
conditional block grant

00:08:25.910 --> 00:08:27.990 align:middle line:90%
example from last lecture.

00:08:27.990 --> 00:08:29.130 align:middle line:90%
The whole budget shrinks.

00:08:29.130 --> 00:08:34.409 align:middle line:84%
So basically what happens is,
person X continues to go to C.

00:08:34.409 --> 00:08:36.230 align:middle line:90%
They continue to get education.

00:08:36.230 --> 00:08:41.150 align:middle line:84%
But now person Y also gets
more education and person

00:08:41.150 --> 00:08:43.190 align:middle line:90%
Z gets more education.

00:08:43.190 --> 00:08:47.490 align:middle line:84%
So now you unambiguously
increase educational attainment.

00:08:47.490 --> 00:08:53.530 align:middle line:84%
So relative to a simple,
limited public education system,

00:08:53.530 --> 00:08:57.130 align:middle line:84%
by giving a voucher,
you can unambiguously

00:08:57.130 --> 00:08:59.730 align:middle line:90%
increase educational attainment.

00:08:59.730 --> 00:09:02.250 align:middle line:84%
And this is one of three
arguments supporting

00:09:02.250 --> 00:09:04.250 align:middle line:84%
what has become a very
significant voucher

00:09:04.250 --> 00:09:05.850 align:middle line:90%
movement in the US--

00:09:05.850 --> 00:09:08.690 align:middle line:84%
a movement in the US
and around the world

00:09:08.690 --> 00:09:10.490 align:middle line:84%
to allow students to
essentially, instead

00:09:10.490 --> 00:09:12.750 align:middle line:84%
of being forced to go
to the public schools,

00:09:12.750 --> 00:09:14.970 align:middle line:84%
to be given a choice
where they can literally

00:09:14.970 --> 00:09:17.090 align:middle line:84%
direct their dollars
to the public school

00:09:17.090 --> 00:09:19.090 align:middle line:90%
or to other alternatives.

00:09:19.090 --> 00:09:22.530 align:middle line:84%
And there are three arguments
people make for vouchers.

00:09:22.530 --> 00:09:26.170 align:middle line:84%
One is the crowd out
argument, that it

00:09:26.170 --> 00:09:29.210 align:middle line:84%
ends this crowd out of group
y, and it actually increases

00:09:29.210 --> 00:09:32.370 align:middle line:90%
attainment for group Z as well.

00:09:32.370 --> 00:09:36.530 align:middle line:84%
The second argument
that people make

00:09:36.530 --> 00:09:44.830 align:middle line:84%
is a consumer sovereignty
argument, that basically, look--

00:09:44.830 --> 00:09:47.430 align:middle line:90%


00:09:47.430 --> 00:09:50.590 align:middle line:90%
I spelled sovereignty, whatever.

00:09:50.590 --> 00:09:53.790 align:middle line:84%
Basically, look, we
think we should respect

00:09:53.790 --> 00:09:55.170 align:middle line:90%
the consumer of lots of things.

00:09:55.170 --> 00:09:57.295 align:middle line:84%
Why do we think the government
knows better than we

00:09:57.295 --> 00:09:59.410 align:middle line:90%
do what the best school is?

00:09:59.410 --> 00:10:03.090 align:middle line:84%
The government may just stick
kids in some crappy school.

00:10:03.090 --> 00:10:07.390 align:middle line:84%
Let's let people decide
what's best for their kids.

00:10:07.390 --> 00:10:09.110 align:middle line:84%
And an advantage
of allowing that

00:10:09.110 --> 00:10:15.110 align:middle line:84%
is a third benefit, which is
efficiency, which is basically

00:10:15.110 --> 00:10:18.310 align:middle line:90%
efficiency from shopping.

00:10:18.310 --> 00:10:22.870 align:middle line:84%
If people can shop, they'll
choose the best schools.

00:10:22.870 --> 00:10:25.110 align:middle line:90%
What are local public schools?

00:10:25.110 --> 00:10:27.770 align:middle line:84%
They're government-sanctioned
monopolies.

00:10:27.770 --> 00:10:29.770 align:middle line:84%
When you have a
government-sanctioned monopoly,

00:10:29.770 --> 00:10:33.570 align:middle line:84%
it's by definition going to
be operating inefficiently.

00:10:33.570 --> 00:10:35.800 align:middle line:90%
It's a nonprofit monopoly.

00:10:35.800 --> 00:10:37.550 align:middle line:84%
A for-profit monopoly
operates efficiently

00:10:37.550 --> 00:10:39.870 align:middle line:90%
and sucks up all the profits.

00:10:39.870 --> 00:10:41.750 align:middle line:84%
But a nonprofit monopoly
has no incentive

00:10:41.750 --> 00:10:45.370 align:middle line:84%
to operate efficiently because
it can't keep the money.

00:10:45.370 --> 00:10:48.170 align:middle line:84%
So the last thing you want
is a nonprofit monopoly.

00:10:48.170 --> 00:10:49.710 align:middle line:84%
It's not the last
thing you want,

00:10:49.710 --> 00:10:51.543 align:middle line:84%
but it's costly to have
a nonprofit monopoly

00:10:51.543 --> 00:10:53.710 align:middle line:84%
because there's no incentive
to operate efficiently.

00:10:53.710 --> 00:10:56.650 align:middle line:84%
If operating efficiently
is stressful, why bother?

00:10:56.650 --> 00:10:59.370 align:middle line:90%
You get the kids no matter what.

00:10:59.370 --> 00:11:03.050 align:middle line:84%
So that's the clear arguments
for a voucher system.

00:11:03.050 --> 00:11:06.650 align:middle line:84%
And that is why there's a
strong advocacy typically

00:11:06.650 --> 00:11:08.430 align:middle line:84%
on the conservative
side of the aisle.

00:11:08.430 --> 00:11:09.730 align:middle line:84%
But this is a little
more bipartisan

00:11:09.730 --> 00:11:11.310 align:middle line:84%
than some other things
we'll talk about.

00:11:11.310 --> 00:11:12.977 align:middle line:84%
It's typically
conservative, but there's

00:11:12.977 --> 00:11:17.598 align:middle line:84%
a little more bipartisan
appeal to this for vouchers.

00:11:17.598 --> 00:11:19.390 align:middle line:84%
So what are the arguments
against vouchers?

00:11:19.390 --> 00:11:22.810 align:middle line:90%


00:11:22.810 --> 00:11:23.670 align:middle line:90%
Why not vouchers?

00:11:23.670 --> 00:11:24.470 align:middle line:90%
Enoch.

00:11:24.470 --> 00:11:26.130 align:middle line:84%
AUDIENCE: In the
transition phase,

00:11:26.130 --> 00:11:32.242 align:middle line:84%
it would harm [INAUDIBLE]
things that [INAUDIBLE].

00:11:32.242 --> 00:11:34.310 align:middle line:84%
JON GRUBER: What about
the kids left behind?

00:11:34.310 --> 00:11:36.718 align:middle line:84%
Remember, what vouchers do
is they say-- basically,

00:11:36.718 --> 00:11:38.510 align:middle line:84%
you take your voucher
go to another school.

00:11:38.510 --> 00:11:39.710 align:middle line:90%
And the idea the efficiency--

00:11:39.710 --> 00:11:41.960 align:middle line:84%
I should have said this, by
the way, a little clearer.

00:11:41.960 --> 00:11:44.560 align:middle line:84%
The way the efficiency works
is, when you go to the school,

00:11:44.560 --> 00:11:46.220 align:middle line:90%
you bring your dollars with you.

00:11:46.220 --> 00:11:47.720 align:middle line:84%
So the good school
get more dollars.

00:11:47.720 --> 00:11:49.095 align:middle line:84%
The bad schools
get less dollars.

00:11:49.095 --> 00:11:51.710 align:middle line:84%
And ultimately, if it's a
company, goes out of business.

00:11:51.710 --> 00:11:52.960 align:middle line:90%
That's the idea of efficiency.

00:11:52.960 --> 00:11:54.900 align:middle line:84%
Efficiency works
through exit and entry.

00:11:54.900 --> 00:11:56.900 align:middle line:84%
The problem Enoch
is pointing out

00:11:56.900 --> 00:11:58.900 align:middle line:84%
is, if somebody's got
an absent parent who's

00:11:58.900 --> 00:12:01.280 align:middle line:84%
not paying attention and the
school goes out of business,

00:12:01.280 --> 00:12:02.820 align:middle line:90%
they're screwed.

00:12:02.820 --> 00:12:05.780 align:middle line:84%
So basically, in some
sense, the problem

00:12:05.780 --> 00:12:09.120 align:middle line:84%
is you are essentially allowing
people to make the best choice.

00:12:09.120 --> 00:12:11.340 align:middle line:84%
But you're relying on
family utility maximization

00:12:11.340 --> 00:12:12.930 align:middle line:84%
that they will make
the best choice.

00:12:12.930 --> 00:12:15.180 align:middle line:84%
And the ones who don't make
that choice end up getting

00:12:15.180 --> 00:12:19.220 align:middle line:84%
left behind in increasingly
poorer and poorer schools.

00:12:19.220 --> 00:12:21.300 align:middle line:90%
So that's one problem.

00:12:21.300 --> 00:12:23.520 align:middle line:84%
What other what other
problems are there?

00:12:23.520 --> 00:12:28.380 align:middle line:90%


00:12:28.380 --> 00:12:30.920 align:middle line:84%
Well, this is a related
one to this, to this one.

00:12:30.920 --> 00:12:31.880 align:middle line:90%
Let's come to this.

00:12:31.880 --> 00:12:34.267 align:middle line:84%
What's the other problem
with this argument?

00:12:34.267 --> 00:12:35.600 align:middle line:90%
What's wrong with this argument?

00:12:35.600 --> 00:12:38.700 align:middle line:90%


00:12:38.700 --> 00:12:39.220 align:middle line:90%
Yeah.

00:12:39.220 --> 00:12:40.860 align:middle line:90%
AUDIENCE: [INAUDIBLE]

00:12:40.860 --> 00:12:42.680 align:middle line:84%
JON GRUBER: It's
hard to shop people.

00:12:42.680 --> 00:12:43.780 align:middle line:90%
There's bad information.

00:12:43.780 --> 00:12:45.320 align:middle line:90%
People don't do it well.

00:12:45.320 --> 00:12:50.140 align:middle line:84%
So there's basically an
imperfect market for schools.

00:12:50.140 --> 00:12:53.117 align:middle line:84%
Both market imperfections
and market power

00:12:53.117 --> 00:12:55.200 align:middle line:84%
are going to make it that
you won't get efficiency

00:12:55.200 --> 00:12:56.640 align:middle line:90%
from shopping.

00:12:56.640 --> 00:12:59.347 align:middle line:84%
So you may do better
from shopping.

00:12:59.347 --> 00:13:01.680 align:middle line:84%
But the notion is, the first
best is clearly wrong given

00:13:01.680 --> 00:13:03.560 align:middle line:90%
imperfections in this market.

00:13:03.560 --> 00:13:05.740 align:middle line:84%
So the second thing is
market imperfections.

00:13:05.740 --> 00:13:10.560 align:middle line:90%


00:13:10.560 --> 00:13:12.760 align:middle line:84%
So that's what's wrong
with that argument.

00:13:12.760 --> 00:13:14.400 align:middle line:84%
What's wrong with
this argument--

00:13:14.400 --> 00:13:18.037 align:middle line:90%
consumer sovereignty?

00:13:18.037 --> 00:13:19.620 align:middle line:84%
How would you argue
back against that?

00:13:19.620 --> 00:13:23.280 align:middle line:90%


00:13:23.280 --> 00:13:23.800 align:middle line:90%
Steven.

00:13:23.800 --> 00:13:27.220 align:middle line:84%
AUDIENCE: [INAUDIBLE] consumers
are able to switch schools,

00:13:27.220 --> 00:13:29.907 align:middle line:84%
so if the nicer school
is further away.

00:13:29.907 --> 00:13:32.240 align:middle line:84%
JON GRUBER: No, but that would
be a market imperfection,

00:13:32.240 --> 00:13:33.800 align:middle line:90%
or what gets left behind.

00:13:33.800 --> 00:13:36.020 align:middle line:84%
But to relate to that,
what else concerns you?

00:13:36.020 --> 00:13:36.820 align:middle line:90%
Yeah.

00:13:36.820 --> 00:13:39.480 align:middle line:84%
AUDIENCE: How do we
know that parents know

00:13:39.480 --> 00:13:40.920 align:middle line:90%
what's best for their children?

00:13:40.920 --> 00:13:42.260 align:middle line:84%
JON GRUBER: Yeah, how do we
know the parents are going

00:13:42.260 --> 00:13:44.500 align:middle line:84%
to choose a school that
delivers the socially

00:13:44.500 --> 00:13:46.420 align:middle line:90%
optimal outcome to their kids?

00:13:46.420 --> 00:13:49.355 align:middle line:84%
I mean, if you're
in Texas and you

00:13:49.355 --> 00:13:50.980 align:middle line:84%
want to compete for
the best resources,

00:13:50.980 --> 00:13:52.480 align:middle line:84%
you offer the best
football team.

00:13:52.480 --> 00:13:54.340 align:middle line:84%
You don't offer the
best math classes,

00:13:54.340 --> 00:13:57.260 align:middle line:84%
because basically the high
schools with good football teams

00:13:57.260 --> 00:13:59.080 align:middle line:90%
get all the rich parents.

00:13:59.080 --> 00:14:00.940 align:middle line:90%
They get a lot of money.

00:14:00.940 --> 00:14:03.540 align:middle line:84%
Is that what we want, we're in
a market where high schools are

00:14:03.540 --> 00:14:06.620 align:middle line:84%
chosen based on their football
team, not their educational

00:14:06.620 --> 00:14:07.980 align:middle line:90%
attainment?

00:14:07.980 --> 00:14:13.220 align:middle line:84%
So basically, the
problem is that you

00:14:13.220 --> 00:14:17.780 align:middle line:84%
could have excessive
specialization, that basically,

00:14:17.780 --> 00:14:23.780 align:middle line:84%
parents say, look, I care
about my kid spending

00:14:23.780 --> 00:14:31.280 align:middle line:84%
the entire class learning
that evolution is fake

00:14:31.280 --> 00:14:33.860 align:middle line:90%
and creationism is the truth.

00:14:33.860 --> 00:14:35.300 align:middle line:90%
Do we want that?

00:14:35.300 --> 00:14:37.480 align:middle line:90%
This is not just a vague idea.

00:14:37.480 --> 00:14:39.280 align:middle line:84%
There was actually
a massive exposé

00:14:39.280 --> 00:14:44.612 align:middle line:84%
of the worst schools in America
by objective school tests.

00:14:44.612 --> 00:14:46.320 align:middle line:84%
Certainly, the worst
schools in the state

00:14:46.320 --> 00:14:49.120 align:middle line:84%
of New York by school
tests are a set

00:14:49.120 --> 00:14:51.680 align:middle line:84%
of specialized
Hasidic high schools--

00:14:51.680 --> 00:14:56.120 align:middle line:84%
Hasidic is a sect of Judaism,
in New York City, which

00:14:56.120 --> 00:14:59.720 align:middle line:84%
are set up as essentially
religious schools masquerading

00:14:59.720 --> 00:15:02.560 align:middle line:90%
as educational institutions.

00:15:02.560 --> 00:15:04.000 align:middle line:84%
The students in
those schools are

00:15:04.000 --> 00:15:06.680 align:middle line:84%
uniformly, on every single
test, the very worst students

00:15:06.680 --> 00:15:07.640 align:middle line:90%
in New York State.

00:15:07.640 --> 00:15:09.280 align:middle line:84%
Students who have
been those schools

00:15:09.280 --> 00:15:11.420 align:middle line:84%
say they come out
totally unprepared.

00:15:11.420 --> 00:15:13.300 align:middle line:84%
They don't take math
or reading or anything.

00:15:13.300 --> 00:15:15.800 align:middle line:84%
They just learn
religious studies,

00:15:15.800 --> 00:15:19.400 align:middle line:84%
and they come out unprepared
to live in modern society.

00:15:19.400 --> 00:15:22.520 align:middle line:84%
But these are private
schools and they

00:15:22.520 --> 00:15:24.320 align:middle line:90%
are sanctioned by the state.

00:15:24.320 --> 00:15:28.040 align:middle line:84%
And basically, you have
excessive specialization.

00:15:28.040 --> 00:15:30.500 align:middle line:84%
Now, in principle--
yeah, Steven.

00:15:30.500 --> 00:15:35.320 align:middle line:84%
AUDIENCE: [INAUDIBLE] is there
a way to open up [INAUDIBLE]?

00:15:35.320 --> 00:15:36.820 align:middle line:84%
JON GRUBER: Yeah,
so in principle,

00:15:36.820 --> 00:15:39.060 align:middle line:84%
you could try to
address that by saying,

00:15:39.060 --> 00:15:41.580 align:middle line:84%
OK, there's certain
things you have to teach,

00:15:41.580 --> 00:15:44.540 align:middle line:84%
certain standards
you have to reach.

00:15:44.540 --> 00:15:46.778 align:middle line:84%
But in practice,
in the limit, it

00:15:46.778 --> 00:15:48.820 align:middle line:84%
might just end up being
easier to run the school.

00:15:48.820 --> 00:15:50.140 align:middle line:84%
I mean, in some sense,
given how difficult

00:15:50.140 --> 00:15:52.240 align:middle line:84%
it is to maintain those
standards and monitor them,

00:15:52.240 --> 00:15:54.320 align:middle line:84%
you got at some point say you
really want to just do that.

00:15:54.320 --> 00:15:57.000 align:middle line:84%
And that's, in some sense,
the whole privatization debate

00:15:57.000 --> 00:15:59.860 align:middle line:84%
we got into chapter 7,
which is it better to let

00:15:59.860 --> 00:16:01.700 align:middle line:84%
a private company do
it and try to monitor

00:16:01.700 --> 00:16:03.367 align:middle line:84%
the quality and the
product, or you have

00:16:03.367 --> 00:16:06.620 align:middle line:90%
the government do it itself?

00:16:06.620 --> 00:16:07.120 align:middle line:90%
What else?

00:16:07.120 --> 00:16:08.662 align:middle line:84%
What's another
problem with vouchers?

00:16:08.662 --> 00:16:13.260 align:middle line:90%


00:16:13.260 --> 00:16:13.760 align:middle line:90%
Yeah.

00:16:13.760 --> 00:16:15.740 align:middle line:84%
AUDIENCE: [INAUDIBLE]
equity issue.

00:16:15.740 --> 00:16:18.320 align:middle line:84%
So you're paying those who
are already going [INAUDIBLE].

00:16:18.320 --> 00:16:20.860 align:middle line:84%
JON GRUBER: Awesome,
great point.

00:16:20.860 --> 00:16:22.980 align:middle line:84%
Think about the
equity implications.

00:16:22.980 --> 00:16:26.260 align:middle line:90%
Who is likely to be person Z?

00:16:26.260 --> 00:16:27.780 align:middle line:90%
A rich person.

00:16:27.780 --> 00:16:29.740 align:middle line:90%
Who's likely to person X?

00:16:29.740 --> 00:16:31.058 align:middle line:90%
A poor person.

00:16:31.058 --> 00:16:33.100 align:middle line:84%
Now, in this case, it's
not true because they all

00:16:33.100 --> 00:16:34.200 align:middle line:90%
have the same budget.

00:16:34.200 --> 00:16:37.040 align:middle line:84%
But in general, who sends
their kids to private schools

00:16:37.040 --> 00:16:38.320 align:middle line:90%
is richer people.

00:16:38.320 --> 00:16:40.440 align:middle line:84%
And for those
people, we are just

00:16:40.440 --> 00:16:42.860 align:middle line:84%
paying them to do something
they were already going to do.

00:16:42.860 --> 00:16:45.400 align:middle line:84%
We're inducing extra
education, but not

00:16:45.400 --> 00:16:48.920 align:middle line:84%
through changing their behavior
just by giving them more money.

00:16:48.920 --> 00:16:51.640 align:middle line:84%
We are going to spend
a lot of the taxation

00:16:51.640 --> 00:16:56.000 align:middle line:84%
section of this course talking
about the concept of marginal

00:16:56.000 --> 00:16:58.680 align:middle line:90%
versus inframarginal consumers.

00:16:58.680 --> 00:17:01.520 align:middle line:84%
A marginal consumer
is one whose behavior

00:17:01.520 --> 00:17:05.599 align:middle line:84%
is changed by a change
in government policy.

00:17:05.599 --> 00:17:07.901 align:middle line:84%
An inframarginal
consumer is one who

00:17:07.901 --> 00:17:09.359 align:middle line:84%
benefits from the
government policy

00:17:09.359 --> 00:17:11.493 align:middle line:90%
without their behavior changing.

00:17:11.493 --> 00:17:13.160 align:middle line:84%
When you put in a
policy that's designed

00:17:13.160 --> 00:17:16.400 align:middle line:84%
to change behavior, i.e.,
to increase education,

00:17:16.400 --> 00:17:19.258 align:middle line:84%
then all the money you give
to rich people who are already

00:17:19.258 --> 00:17:21.300 align:middle line:84%
send their kids to private
schools inframarginal.

00:17:21.300 --> 00:17:23.467 align:middle line:84%
It's just a waste from the
government's perspective.

00:17:23.467 --> 00:17:25.480 align:middle line:90%
It's only redistributional.

00:17:25.480 --> 00:17:29.042 align:middle line:84%
Marginal changes have
efficiency consequences.

00:17:29.042 --> 00:17:30.500 align:middle line:84%
If I induce someone
to go to school

00:17:30.500 --> 00:17:33.100 align:middle line:84%
who isn't going to school,
that's a marginal change.

00:17:33.100 --> 00:17:35.220 align:middle line:84%
That is an efficiency
consequence.

00:17:35.220 --> 00:17:37.860 align:middle line:84%
If I take someone who's
already going to school

00:17:37.860 --> 00:17:41.060 align:middle line:84%
and just give them money, that
is an inframarginal change.

00:17:41.060 --> 00:17:45.900 align:middle line:84%
It's redistributive, but it
has no efficiency consequences.

00:17:45.900 --> 00:17:48.045 align:middle line:84%
Look, more people in
group Z go to school,

00:17:48.045 --> 00:17:49.920 align:middle line:84%
but they go to school
because they're richer.

00:17:49.920 --> 00:17:51.140 align:middle line:84%
We could have more
people go to Z school

00:17:51.140 --> 00:17:52.973 align:middle line:84%
by just redistributing
money to rich people.

00:17:52.973 --> 00:17:54.860 align:middle line:84%
We wouldn't have
to have vouchers.

00:17:54.860 --> 00:17:58.090 align:middle line:84%
So basically, if we
think about marginal,

00:17:58.090 --> 00:18:00.940 align:middle line:84%
inframarginal the marginal
piece is about efficiency.

00:18:00.940 --> 00:18:04.220 align:middle line:84%
The inframarginal piece
is about redistribution.

00:18:04.220 --> 00:18:07.240 align:middle line:84%
So you have to ask yourself,
well, who are redistributing to?

00:18:07.240 --> 00:18:08.757 align:middle line:84%
Well, vouchers,
we're redistributing

00:18:08.757 --> 00:18:11.340 align:middle line:84%
towards rich people because they
were the ones already sending

00:18:11.340 --> 00:18:13.860 align:middle line:90%
their kids to private school.

00:18:13.860 --> 00:18:17.740 align:middle line:84%
So it becomes an inefficient
use of public dollars

00:18:17.740 --> 00:18:20.700 align:middle line:84%
to offer a voucher,
because yes, you

00:18:20.700 --> 00:18:23.900 align:middle line:84%
might induce some poor people
to get to go to private school.

00:18:23.900 --> 00:18:26.420 align:middle line:84%
But you're also buying out
rich people already sending

00:18:26.420 --> 00:18:27.900 align:middle line:90%
their kids to private school.

00:18:27.900 --> 00:18:30.400 align:middle line:84%
Now, in practice, once again,
you could deal with this.

00:18:30.400 --> 00:18:34.470 align:middle line:84%
You could have
income-related vouchers.

00:18:34.470 --> 00:18:36.930 align:middle line:84%
And in practice, that is
something you could approach.

00:18:36.930 --> 00:18:38.430 align:middle line:84%
But in some sense,
then the question

00:18:38.430 --> 00:18:40.190 align:middle line:90%
is, where's the income cutoff?

00:18:40.190 --> 00:18:44.310 align:middle line:84%
And really, remember, on this
x-axis, it is not income.

00:18:44.310 --> 00:18:46.083 align:middle line:84%
It's desired
educational spending.

00:18:46.083 --> 00:18:47.750 align:middle line:84%
So you really like
to target the voucher

00:18:47.750 --> 00:18:50.870 align:middle line:84%
by who really needs
to push to send

00:18:50.870 --> 00:18:53.790 align:middle line:84%
their kid to private school
versus who's already sending

00:18:53.790 --> 00:18:54.970 align:middle line:90%
their kid to private school.

00:18:54.970 --> 00:18:58.510 align:middle line:84%
Well, that's correlated with
income, but not perfectly.

00:18:58.510 --> 00:19:01.090 align:middle line:84%
So cutting by income doesn't
really solve the problem.

00:19:01.090 --> 00:19:03.750 align:middle line:84%
You really want to cut by
underlying educational spending

00:19:03.750 --> 00:19:04.710 align:middle line:90%
desire.

00:19:04.710 --> 00:19:08.750 align:middle line:84%
And that's immeasurable
So another problem

00:19:08.750 --> 00:19:09.810 align:middle line:90%
is the equity problem.

00:19:09.810 --> 00:19:10.310 align:middle line:90%
Yeah.

00:19:10.310 --> 00:19:12.150 align:middle line:84%
AUDIENCE: Aside from,
like, whether or not

00:19:12.150 --> 00:19:14.730 align:middle line:84%
their children are currently
enrolled in a private school,

00:19:14.730 --> 00:19:17.150 align:middle line:84%
are there any [INAUDIBLE]
preference metrics [INAUDIBLE]

00:19:17.150 --> 00:19:19.170 align:middle line:90%
might approach that?

00:19:19.170 --> 00:19:20.530 align:middle line:90%
JON GRUBER: Not really.

00:19:20.530 --> 00:19:23.990 align:middle line:84%
I mean, no, because actually,
the truth is private school

00:19:23.990 --> 00:19:27.670 align:middle line:84%
attendance-- while I
parodied the private school

00:19:27.670 --> 00:19:31.430 align:middle line:84%
attendance that we think
about is Andover and Exeter.

00:19:31.430 --> 00:19:33.330 align:middle line:84%
But 90% of kids in
private school in America

00:19:33.330 --> 00:19:35.955 align:middle line:84%
go to parochial schools, which
are actually not that expensive,

00:19:35.955 --> 00:19:38.030 align:middle line:84%
and actually attended
not by the poorest,

00:19:38.030 --> 00:19:40.450 align:middle line:84%
but typically often not
by the richest either.

00:19:40.450 --> 00:19:44.170 align:middle line:84%
So in some sense it is hard
to actually income is actually

00:19:44.170 --> 00:19:46.390 align:middle line:90%
a reason is not a great proxy.

00:19:46.390 --> 00:19:48.850 align:middle line:84%
It's correlated with private
school demand and education,

00:19:48.850 --> 00:19:51.993 align:middle line:84%
but it's not actually an
outstanding proxy for it.

00:19:51.993 --> 00:19:54.410 align:middle line:84%
And so basically, the problem
is you deal with the equity,

00:19:54.410 --> 00:19:55.850 align:middle line:84%
but you don't really
get the vouchers

00:19:55.850 --> 00:19:57.010 align:middle line:90%
who you want them to go to.

00:19:57.010 --> 00:20:00.122 align:middle line:84%
You want to induce the people
who-- you want to get them to x.

00:20:00.122 --> 00:20:02.330 align:middle line:84%
You want the people who
you're going to most increase

00:20:02.330 --> 00:20:04.490 align:middle line:84%
their educational attainment,
but you don't know

00:20:04.490 --> 00:20:06.210 align:middle line:90%
how to target them that way.

00:20:06.210 --> 00:20:07.148 align:middle line:90%
Does that make sense?

00:20:07.148 --> 00:20:08.690 align:middle line:84%
That's a very
important concept we'll

00:20:08.690 --> 00:20:11.232 align:middle line:84%
come back to over and over again
when we talk about taxation.

00:20:11.232 --> 00:20:13.450 align:middle line:90%


00:20:13.450 --> 00:20:15.930 align:middle line:84%
One other problem
that's very important

00:20:15.930 --> 00:20:21.170 align:middle line:90%
here is, what about segregation?

00:20:21.170 --> 00:20:24.530 align:middle line:84%
And segregation is
interesting because it's

00:20:24.530 --> 00:20:25.950 align:middle line:90%
on both sides of the line.

00:20:25.950 --> 00:20:31.510 align:middle line:90%


00:20:31.510 --> 00:20:34.050 align:middle line:84%
Voucher opponents say, look,
what's going to happen?

00:20:34.050 --> 00:20:37.253 align:middle line:84%
Well, all the motivated
families got their shit together

00:20:37.253 --> 00:20:38.170 align:middle line:90%
and pulled their kids.

00:20:38.170 --> 00:20:41.470 align:middle line:90%
It's related to the first point.

00:20:41.470 --> 00:20:44.390 align:middle line:84%
All the motivated families
that had their shit

00:20:44.390 --> 00:20:46.690 align:middle line:84%
together pulled their kids
out of the public schools,

00:20:46.690 --> 00:20:48.670 align:middle line:90%
put them in the private schools.

00:20:48.670 --> 00:20:51.370 align:middle line:84%
The ones who are left behind
are the less motivated,

00:20:51.370 --> 00:20:54.270 align:middle line:84%
the people with less odds
of succeeding anyway.

00:20:54.270 --> 00:20:56.190 align:middle line:84%
And so you're further
segregating society

00:20:56.190 --> 00:20:59.270 align:middle line:84%
into those who are likely to
succeed and those who are not.

00:20:59.270 --> 00:21:03.910 align:middle line:84%
Now, supporters of vouchers
actually recognized

00:21:03.910 --> 00:21:06.310 align:middle line:84%
that argument and said, well,
that's actually bullshit

00:21:06.310 --> 00:21:08.518 align:middle line:84%
because we already have
incredibly segregated schools

00:21:08.518 --> 00:21:09.910 align:middle line:90%
in America today.

00:21:09.910 --> 00:21:16.870 align:middle line:84%
So the fact is that the
typical white student attends

00:21:16.870 --> 00:21:22.110 align:middle line:84%
a school that's 75% white,
but 40% of minority students

00:21:22.110 --> 00:21:25.990 align:middle line:84%
attend schools that are
90% to 100% minority.

00:21:25.990 --> 00:21:32.990 align:middle line:84%
So basically, this is
really the idea that, look,

00:21:32.990 --> 00:21:35.730 align:middle line:84%
we're already
segregated by race.

00:21:35.730 --> 00:21:37.650 align:middle line:84%
Maybe segregation by
ability isn't so bad

00:21:37.650 --> 00:21:39.787 align:middle line:84%
if it allows a poor
Black kid who's

00:21:39.787 --> 00:21:41.370 align:middle line:84%
stuck in a minority
school-- but who's

00:21:41.370 --> 00:21:43.430 align:middle line:84%
really able, his parents
want him to succeed,

00:21:43.430 --> 00:21:46.875 align:middle line:84%
to go to a private school
with other white kids.

00:21:46.875 --> 00:21:48.750 align:middle line:84%
Then yeah, you're
separating more by ability,

00:21:48.750 --> 00:21:50.570 align:middle line:84%
but you're separating
less by race.

00:21:50.570 --> 00:21:55.570 align:middle line:84%
So this is a tough
one to evaluate.

00:21:55.570 --> 00:21:57.730 align:middle line:84%
That's the pros and
cons of vouchers.

00:21:57.730 --> 00:22:00.677 align:middle line:84%
This is how I want you to
learn to think about problems.

00:22:00.677 --> 00:22:03.010 align:middle line:84%
There's almost nothing we
learn about in this class that

00:22:03.010 --> 00:22:04.770 align:middle line:90%
has an easy answer.

00:22:04.770 --> 00:22:07.832 align:middle line:90%
This is not E equals mc squared.

00:22:07.832 --> 00:22:09.790 align:middle line:84%
There's almost nothing--
not that it's so easy.

00:22:09.790 --> 00:22:11.488 align:middle line:90%
But there's a formula.

00:22:11.488 --> 00:22:13.030 align:middle line:84%
So it's not [INAUDIBLE]
just formula.

00:22:13.030 --> 00:22:14.072 align:middle line:90%
There's always tradeoffs.

00:22:14.072 --> 00:22:15.593 align:middle line:90%
And we want to think about how--

00:22:15.593 --> 00:22:17.010 align:middle line:84%
want to get you
trained up and how

00:22:17.010 --> 00:22:20.170 align:middle line:84%
to think about
those tradeoffs OK.

00:22:20.170 --> 00:22:20.752 align:middle line:90%
Yeah, Enoch.

00:22:20.752 --> 00:22:23.210 align:middle line:84%
AUDIENCE: Is there any evidence,
outside of moral argument,

00:22:23.210 --> 00:22:25.730 align:middle line:90%
segregation is a bad thing?

00:22:25.730 --> 00:22:31.510 align:middle line:84%
JON GRUBER: Actually,
it's not clear-- well,

00:22:31.510 --> 00:22:33.410 align:middle line:84%
two types of literature
on segregation.

00:22:33.410 --> 00:22:34.990 align:middle line:84%
So one type is you
might specifically

00:22:34.990 --> 00:22:38.570 align:middle line:84%
say, segregation in
education, is that bad?

00:22:38.570 --> 00:22:40.730 align:middle line:84%
The evidence there
is mixed on that one,

00:22:40.730 --> 00:22:43.630 align:middle line:84%
because sometimes putting
students who are very high

00:22:43.630 --> 00:22:46.498 align:middle line:84%
achieving together has
positive externalities.

00:22:46.498 --> 00:22:48.790 align:middle line:84%
And having a low-achieving
kid with high-achieving kids

00:22:48.790 --> 00:22:50.915 align:middle line:84%
can really have a big
negative externality on them,

00:22:50.915 --> 00:22:52.550 align:middle line:90%
so that evidence is mixed.

00:22:52.550 --> 00:22:55.072 align:middle line:84%
There's more general evidence
of segregation in society,

00:22:55.072 --> 00:22:56.530 align:middle line:84%
and that evidence
is pretty uniform

00:22:56.530 --> 00:22:58.630 align:middle line:84%
that's bad for the people
who get left behind.

00:22:58.630 --> 00:23:00.030 align:middle line:84%
There's not great
evidence on how good

00:23:00.030 --> 00:23:01.950 align:middle line:84%
it is for people who
don't get left behind.

00:23:01.950 --> 00:23:03.950 align:middle line:84%
The trick with all this
stuff is you really want

00:23:03.950 --> 00:23:05.190 align:middle line:90%
to care about social welfare.

00:23:05.190 --> 00:23:07.732 align:middle line:84%
It's pretty clear it's bad for
the folks who get left behind.

00:23:07.732 --> 00:23:10.430 align:middle line:84%
It's less clear if it's
overall bad for society or not.

00:23:10.430 --> 00:23:12.430 align:middle line:84%
One sense in which it is
overall bad for society

00:23:12.430 --> 00:23:14.563 align:middle line:84%
is a lot of political
economy research, which

00:23:14.563 --> 00:23:16.230 align:middle line:84%
shows that more
segregated societies are

00:23:16.230 --> 00:23:18.950 align:middle line:84%
less likely to provide public
goods that benefit everyone.

00:23:18.950 --> 00:23:20.990 align:middle line:84%
Because if you don't
know the other folk,

00:23:20.990 --> 00:23:21.970 align:middle line:84%
if you're not with
the other folk,

00:23:21.970 --> 00:23:23.303 align:middle line:90%
you don't want to help them out.

00:23:23.303 --> 00:23:27.610 align:middle line:84%
So we talked about social
capital and altruism.

00:23:27.610 --> 00:23:29.730 align:middle line:84%
That is, there's
less social capital

00:23:29.730 --> 00:23:32.570 align:middle line:90%
and more segregated societies.

00:23:32.570 --> 00:23:34.850 align:middle line:90%
Other questions?

00:23:34.850 --> 00:23:39.230 align:middle line:84%
Now, when you're in a situation
like this, what do you do?

00:23:39.230 --> 00:23:40.772 align:middle line:84%
You call up the
empirical economists.

00:23:40.772 --> 00:23:43.355 align:middle line:84%
And you say, well, we don't know
what's right or what's wrong.

00:23:43.355 --> 00:23:43.890 align:middle line:90%
You tell us.

00:23:43.890 --> 00:23:45.723 align:middle line:84%
So that's what empirical
economists come in.

00:23:45.723 --> 00:23:47.390 align:middle line:90%
So we have a lot of evidence.

00:23:47.390 --> 00:23:49.730 align:middle line:84%
There's been a huge
literature built up

00:23:49.730 --> 00:23:54.370 align:middle line:84%
on thinking about
the effects of reform

00:23:54.370 --> 00:23:56.530 align:middle line:90%
in education markets writ large.

00:23:56.530 --> 00:24:01.610 align:middle line:84%
Now, we don't have a ton
of US evidence on vouchers.

00:24:01.610 --> 00:24:02.950 align:middle line:90%
We have a little evidence.

00:24:02.950 --> 00:24:06.690 align:middle line:84%
The evidence we have actually
comes from a very clever,

00:24:06.690 --> 00:24:09.210 align:middle line:84%
generalized approach that we
use in empirical economics

00:24:09.210 --> 00:24:12.010 align:middle line:84%
these days, which is what's
called the waiting list design

00:24:12.010 --> 00:24:14.810 align:middle line:90%
or randomized lottery design.

00:24:14.810 --> 00:24:17.970 align:middle line:84%
The way vouchers work
when they're assigned

00:24:17.970 --> 00:24:21.130 align:middle line:84%
is essentially, too many kids
want the voucher relative to how

00:24:21.130 --> 00:24:22.378 align:middle line:90%
many vouchers are available.

00:24:22.378 --> 00:24:23.170 align:middle line:90%
They'll limit them.

00:24:23.170 --> 00:24:27.430 align:middle line:84%
To limit the fiscal cost to the
government, they'll limit them.

00:24:27.430 --> 00:24:28.800 align:middle line:90%
Too many kids want it.

00:24:28.800 --> 00:24:30.550 align:middle line:84%
So what they'll do is
decide who gets them

00:24:30.550 --> 00:24:33.585 align:middle line:90%
by lottery, to be fair.

00:24:33.585 --> 00:24:35.210 align:middle line:84%
Once you decide who
gets it by lottery,

00:24:35.210 --> 00:24:36.918 align:middle line:84%
you set up a randomized
trial of the type

00:24:36.918 --> 00:24:39.150 align:middle line:90%
we discussed in chapter 3.

00:24:39.150 --> 00:24:42.190 align:middle line:90%
So you have a lottery.

00:24:42.190 --> 00:24:44.990 align:middle line:84%
And Paul wins and
Valerie loses, then

00:24:44.990 --> 00:24:48.630 align:middle line:84%
you have two identical people,
one of whom won and one of whom

00:24:48.630 --> 00:24:49.487 align:middle line:90%
lost.

00:24:49.487 --> 00:24:51.070 align:middle line:84%
By random chance,
you can compare them

00:24:51.070 --> 00:24:52.987 align:middle line:84%
and see what happens to
them five years later.

00:24:52.987 --> 00:24:54.910 align:middle line:84%
Was it good for them
or bad for them?

00:24:54.910 --> 00:24:57.710 align:middle line:84%
So this randomized
lottery design

00:24:57.710 --> 00:24:59.810 align:middle line:84%
is essentially a way
that society gives you

00:24:59.810 --> 00:25:02.310 align:middle line:84%
a true randomized control trial
without you having to set it

00:25:02.310 --> 00:25:03.840 align:middle line:90%
up and run it yourself.

00:25:03.840 --> 00:25:05.590 align:middle line:84%
And that method has
been used in many ways

00:25:05.590 --> 00:25:07.790 align:middle line:90%
to study voucher programs.

00:25:07.790 --> 00:25:13.912 align:middle line:84%
I think the evidence in the
US is positive but modest.

00:25:13.912 --> 00:25:15.870 align:middle line:84%
I think the evidence
[INAUDIBLE] be interpreted

00:25:15.870 --> 00:25:19.950 align:middle line:90%
as positive but modest.

00:25:19.950 --> 00:25:22.650 align:middle line:84%
The more compelling evidence
comes from other countries

00:25:22.650 --> 00:25:24.923 align:middle line:84%
where voucher programs
are much, much larger.

00:25:24.923 --> 00:25:27.090 align:middle line:84%
My colleague Josh Angrist
did a very important paper

00:25:27.090 --> 00:25:31.590 align:middle line:84%
on Colombia, which covered a
large share of the population,

00:25:31.590 --> 00:25:33.850 align:middle line:84%
and he found very
large positive effects

00:25:33.850 --> 00:25:38.450 align:middle line:84%
on the lottery winners
versus the lottery losers.

00:25:38.450 --> 00:25:40.918 align:middle line:84%
So there is some evidence
from other countries

00:25:40.918 --> 00:25:43.210 align:middle line:84%
where the lotteries are quite
large where it's a more--

00:25:43.210 --> 00:25:45.022 align:middle line:84%
and the US voucher
advocates would argue,

00:25:45.022 --> 00:25:46.730 align:middle line:84%
well, you don't see
big effects in the US

00:25:46.730 --> 00:25:49.770 align:middle line:84%
because you can't get this
effect when just a few people

00:25:49.770 --> 00:25:50.900 align:middle line:90%
are getting vouchers.

00:25:50.900 --> 00:25:52.650 align:middle line:84%
The only way to test
vouchers is give them

00:25:52.650 --> 00:25:55.890 align:middle line:84%
to a huge number of people,
so you let the market react.

00:25:55.890 --> 00:25:58.150 align:middle line:84%
We have what we call in
economics partial equilibrium

00:25:58.150 --> 00:25:59.692 align:middle line:84%
and general equilibrium,
another term

00:25:59.692 --> 00:26:00.900 align:middle line:90%
we'll talk about in taxation.

00:26:00.900 --> 00:26:02.567 align:middle line:84%
Partial equilibria
is holding everything

00:26:02.567 --> 00:26:04.872 align:middle line:84%
else constant, what happens
general equilibrium is

00:26:04.872 --> 00:26:06.830 align:middle line:84%
what happens not holding
other things constant.

00:26:06.830 --> 00:26:08.497 align:middle line:84%
And voucher advocates
would argue, well,

00:26:08.497 --> 00:26:10.130 align:middle line:84%
if you give 100 guys
vouchers and look

00:26:10.130 --> 00:26:11.930 align:middle line:84%
at what happens,
that doesn't tell you

00:26:11.930 --> 00:26:13.305 align:middle line:84%
whether it's good
or bad for them

00:26:13.305 --> 00:26:15.570 align:middle line:84%
because you don't get
the market response.

00:26:15.570 --> 00:26:16.410 align:middle line:90%
Yeah, question.

00:26:16.410 --> 00:26:19.230 align:middle line:84%
AUDIENCE: From the
[? global ?] literature,

00:26:19.230 --> 00:26:21.740 align:middle line:84%
is there any a
correlation that you're

00:26:21.740 --> 00:26:27.180 align:middle line:84%
aware of from [INAUDIBLE]
size of the-- the magnitude

00:26:27.180 --> 00:26:29.682 align:middle line:84%
of the voucher compared
to an individual income?

00:26:29.682 --> 00:26:32.140 align:middle line:84%
JON GRUBER: Yeah, I mean, I
think they're not at that level

00:26:32.140 --> 00:26:32.640 align:middle line:90%
yet.

00:26:32.640 --> 00:26:35.300 align:middle line:84%
This is still just
voucher, no voucher.

00:26:35.300 --> 00:26:42.540 align:middle line:84%
Now, this does, however, raise a
very interesting question, which

00:26:42.540 --> 00:26:45.980 align:middle line:84%
is, when you use
this lottery study,

00:26:45.980 --> 00:26:49.040 align:middle line:84%
you get the effect on the
winners versus the losers.

00:26:49.040 --> 00:26:51.620 align:middle line:84%
But you don't get the
effect on society,

00:26:51.620 --> 00:26:53.328 align:middle line:84%
just like I was saying
about segregation.

00:26:53.328 --> 00:26:55.370 align:middle line:84%
What you care about is
whether society as a whole

00:26:55.370 --> 00:26:56.080 align:middle line:90%
is better off.

00:26:56.080 --> 00:26:57.320 align:middle line:84%
So yeah, the winners
may be better off.

00:26:57.320 --> 00:26:58.580 align:middle line:90%
But are the losers worse off?

00:26:58.580 --> 00:27:00.020 align:middle line:84%
Are the losers
worse off in a way

00:27:00.020 --> 00:27:03.300 align:middle line:84%
that offsets the
gains to the winners?

00:27:03.300 --> 00:27:05.620 align:middle line:84%
There's starting to be
some literature on this.

00:27:05.620 --> 00:27:08.020 align:middle line:84%
In particular, there's a
reasonably sizable voucher

00:27:08.020 --> 00:27:11.280 align:middle line:84%
program in Florida, and
the evidence suggests no.

00:27:11.280 --> 00:27:14.380 align:middle line:84%
Overall, the whole cohort
is better off [INAUDIBLE]

00:27:14.380 --> 00:27:16.700 align:middle line:84%
school choice, maybe
because of the competition,

00:27:16.700 --> 00:27:17.440 align:middle line:90%
however it works.

00:27:17.440 --> 00:27:19.480 align:middle line:90%
Maybe because of better sorting.

00:27:19.480 --> 00:27:21.320 align:middle line:84%
In other words,
segregation is sorting.

00:27:21.320 --> 00:27:22.920 align:middle line:90%
And that can be good or bad.

00:27:22.920 --> 00:27:25.240 align:middle line:84%
Whatever the
reason, the evidence

00:27:25.240 --> 00:27:29.600 align:middle line:84%
seems to be that overall,
the system improves.

00:27:29.600 --> 00:27:32.560 align:middle line:84%
So with vouchers,
the existing evidence

00:27:32.560 --> 00:27:36.760 align:middle line:84%
seems to suggest there be
improved educational outcomes,

00:27:36.760 --> 00:27:40.240 align:middle line:84%
but at a cost of
clearly lower equity

00:27:40.240 --> 00:27:42.797 align:middle line:84%
and the other concerns
that are raised.

00:27:42.797 --> 00:27:44.880 align:middle line:84%
The question is, are there
other alternatives that

00:27:44.880 --> 00:27:45.880 align:middle line:90%
might do better?

00:27:45.880 --> 00:27:48.080 align:middle line:84%
And we've tried a
number of alternatives.

00:27:48.080 --> 00:27:51.920 align:middle line:84%
One alternative is,
instead of having

00:27:51.920 --> 00:27:55.800 align:middle line:84%
vouchers, have free choice,
but only among public schools.

00:27:55.800 --> 00:27:58.780 align:middle line:84%
That is, try to
get these benefits,

00:27:58.780 --> 00:28:01.080 align:middle line:84%
but use it to send incentives
across public schools,

00:28:01.080 --> 00:28:04.280 align:middle line:84%
rather than subsidizing
private entities.

00:28:04.280 --> 00:28:08.460 align:middle line:84%
That's been done a lot, and
there's two forms of that.

00:28:08.460 --> 00:28:12.160 align:middle line:84%
One form is cities like
Chicago or Cambridge,

00:28:12.160 --> 00:28:14.560 align:middle line:84%
where they let you go to
any elementary school you

00:28:14.560 --> 00:28:16.935 align:middle line:84%
want in the city or any high
school you want in the city.

00:28:16.935 --> 00:28:18.760 align:middle line:84%
So where my kids
grew up in Lexington,

00:28:18.760 --> 00:28:20.680 align:middle line:84%
you go to the local elementary
school and the middle school,

00:28:20.680 --> 00:28:21.060 align:middle line:90%
and the high school.

00:28:21.060 --> 00:28:21.940 align:middle line:90%
It's all assigned to you.

00:28:21.940 --> 00:28:23.860 align:middle line:84%
In these cities, you
go to any one you want.

00:28:23.860 --> 00:28:25.943 align:middle line:84%
And you apply and you go
to the best one you want.

00:28:25.943 --> 00:28:27.568 align:middle line:84%
And once again,
there's a waiting list,

00:28:27.568 --> 00:28:28.860 align:middle line:90%
so we can study what happens.

00:28:28.860 --> 00:28:30.937 align:middle line:90%
And the answer is not a lot.

00:28:30.937 --> 00:28:33.020 align:middle line:84%
It doesn't seem like letting
people shuffle around

00:28:33.020 --> 00:28:36.220 align:middle line:84%
like that makes that
much difference.

00:28:36.220 --> 00:28:38.220 align:middle line:84%
The other big change
here that's made

00:28:38.220 --> 00:28:41.660 align:middle line:84%
is the rise of charter
and magnet schools, which

00:28:41.660 --> 00:28:44.300 align:middle line:84%
are essentially
public schools kind

00:28:44.300 --> 00:28:48.860 align:middle line:84%
of outside the existing
regulatory and union guidelines.

00:28:48.860 --> 00:28:53.020 align:middle line:84%
So essentially, a charter
school is typically

00:28:53.020 --> 00:28:55.540 align:middle line:90%
private, often for-profit.

00:28:55.540 --> 00:28:57.180 align:middle line:84%
But they are funded
by the state,

00:28:57.180 --> 00:29:00.640 align:middle line:84%
and they're still
considered public schools,

00:29:00.640 --> 00:29:04.020 align:middle line:84%
although in some sense
they're halfway in between.

00:29:04.020 --> 00:29:05.980 align:middle line:84%
So they're not
private in the sense

00:29:05.980 --> 00:29:07.660 align:middle line:84%
they're heavily
regulated by the state

00:29:07.660 --> 00:29:11.140 align:middle line:84%
and they meet certain
state standards.

00:29:11.140 --> 00:29:14.337 align:middle line:84%
They are private in the
sense that they are not

00:29:14.337 --> 00:29:16.920 align:middle line:84%
subject to some other rules that
public schools are subbed to,

00:29:16.920 --> 00:29:22.480 align:middle line:84%
in particular unionization of
teachers and other standards.

00:29:22.480 --> 00:29:26.520 align:middle line:84%
And once again, people get into
charter schools by lottery.

00:29:26.520 --> 00:29:27.760 align:middle line:90%
There's a huge literature.

00:29:27.760 --> 00:29:29.468 align:middle line:84%
And actually, the
world leaders from that

00:29:29.468 --> 00:29:31.560 align:middle line:84%
are my colleagues Josh
Angrist and Parag Pathak.

00:29:31.560 --> 00:29:33.227 align:middle line:84%
At Blueprint Labs
here at MIT, they've

00:29:33.227 --> 00:29:35.560 align:middle line:84%
done dozens of studies looking
at the effect-- maybe not

00:29:35.560 --> 00:29:37.977 align:middle line:84%
dozens-- but many studies
looking at the effect of charter

00:29:37.977 --> 00:29:38.640 align:middle line:90%
schools.

00:29:38.640 --> 00:29:43.900 align:middle line:84%
And I would say the evidence
is once again, on average,

00:29:43.900 --> 00:29:45.360 align:middle line:90%
positive.

00:29:45.360 --> 00:29:48.360 align:middle line:84%
The evidence seems to be
that charter schools benefit

00:29:48.360 --> 00:29:49.580 align:middle line:90%
the kids who go there.

00:29:49.580 --> 00:29:51.160 align:middle line:90%
And here's the exciting part.

00:29:51.160 --> 00:29:54.440 align:middle line:84%
The benefits are the largest
for the least advantaged kids.

00:29:54.440 --> 00:29:58.520 align:middle line:84%
That's why it's more exciting
than the voucher literature,

00:29:58.520 --> 00:30:00.560 align:middle line:84%
because without giving
extra money to people

00:30:00.560 --> 00:30:02.660 align:middle line:84%
who are already going to private
school, you're not giving away.

00:30:02.660 --> 00:30:04.500 align:middle line:84%
You're just taking people and
shuffling them across schools.

00:30:04.500 --> 00:30:06.182 align:middle line:84%
So no one's getting
extra money here.

00:30:06.182 --> 00:30:08.640 align:middle line:84%
But you're doing so in a way
which actually improves equity

00:30:08.640 --> 00:30:10.280 align:middle line:84%
because the charter schools
are better for the more

00:30:10.280 --> 00:30:11.420 align:middle line:90%
disadvantaged students.

00:30:11.420 --> 00:30:12.800 align:middle line:90%
Why is that?

00:30:12.800 --> 00:30:16.600 align:middle line:84%
Well, the evidence once
again is not determinant.

00:30:16.600 --> 00:30:19.540 align:middle line:84%
But it seems to be, there's a
set of things that correlate

00:30:19.540 --> 00:30:23.580 align:middle line:84%
with success in school, most
importantly things like stronger

00:30:23.580 --> 00:30:28.595 align:middle line:84%
discipline, stronger standards,
wearing uniforms, more norms,

00:30:28.595 --> 00:30:30.220 align:middle line:84%
that basically things
seem to correlate

00:30:30.220 --> 00:30:32.260 align:middle line:90%
with success in school.

00:30:32.260 --> 00:30:36.420 align:middle line:84%
Basically, there's more
zero tolerance strategies.

00:30:36.420 --> 00:30:41.060 align:middle line:84%
Now, that raises separate
issues of equity and fairness,

00:30:41.060 --> 00:30:43.660 align:middle line:90%
et cetera.

00:30:43.660 --> 00:30:46.320 align:middle line:84%
But that is what seems to be
the reason that they do better.

00:30:46.320 --> 00:30:46.820 align:middle line:90%
Yeah.

00:30:46.820 --> 00:30:48.900 align:middle line:84%
AUDIENCE: And those
strategies aren't imposed

00:30:48.900 --> 00:30:50.172 align:middle line:90%
in normal public schools.

00:30:50.172 --> 00:30:52.380 align:middle line:84%
JON GRUBER: No, they're not
imposed in public schools

00:30:52.380 --> 00:30:55.500 align:middle line:84%
because parents would
bitch about it or whatever.

00:30:55.500 --> 00:30:56.870 align:middle line:90%
AUDIENCE: But it's not illegal.

00:30:56.870 --> 00:30:58.120 align:middle line:90%
JON GRUBER: It could be legal.

00:30:58.120 --> 00:31:00.965 align:middle line:84%
The school could be worried
about getting sued, cetera.

00:31:00.965 --> 00:31:01.840 align:middle line:90%
It's a good question.

00:31:01.840 --> 00:31:03.740 align:middle line:84%
I don't know why-- but
some public schools

00:31:03.740 --> 00:31:05.580 align:middle line:90%
are moving towards that.

00:31:05.580 --> 00:31:08.440 align:middle line:84%
But really, the charter schools
have been the lead on that.

00:31:08.440 --> 00:31:08.940 align:middle line:90%
Yeah.

00:31:08.940 --> 00:31:11.280 align:middle line:84%
AUDIENCE: [INAUDIBLE] like
teacher quality channel,

00:31:11.280 --> 00:31:12.740 align:middle line:90%
is there anything [INAUDIBLE]?

00:31:12.740 --> 00:31:14.203 align:middle line:84%
JON GRUBER: That's
a great point.

00:31:14.203 --> 00:31:16.120 align:middle line:84%
The other thing that
charter schools have done

00:31:16.120 --> 00:31:20.320 align:middle line:84%
is moved towards more innovative
ways of hiring and recognizing

00:31:20.320 --> 00:31:22.040 align:middle line:90%
teacher quality.

00:31:22.040 --> 00:31:25.180 align:middle line:84%
So once again, because they're
free, they're more flexible.

00:31:25.180 --> 00:31:26.180 align:middle line:90%
There's no unionization.

00:31:26.180 --> 00:31:28.180 align:middle line:84%
They're more flexible in
terms of hire and fire.

00:31:28.180 --> 00:31:30.240 align:middle line:84%
They'll do things
like hiring people

00:31:30.240 --> 00:31:32.298 align:middle line:84%
who are not trained as
teachers, but have shown

00:31:32.298 --> 00:31:33.840 align:middle line:84%
great aptitude for
that set of skills

00:31:33.840 --> 00:31:36.760 align:middle line:84%
and give them a
shot as a teacher.

00:31:36.760 --> 00:31:38.555 align:middle line:84%
So there's more
flexibility and more effort

00:31:38.555 --> 00:31:40.680 align:middle line:84%
to try to find people who'll
be better in teaching,

00:31:40.680 --> 00:31:43.263 align:middle line:84%
rather than people who've just
traditionally been in teaching.

00:31:43.263 --> 00:31:45.140 align:middle line:90%
So that's a good point.

00:31:45.140 --> 00:31:46.840 align:middle line:84%
It's another thing
they're doing.

00:31:46.840 --> 00:31:49.160 align:middle line:90%
So this has been successful.

00:31:49.160 --> 00:31:53.260 align:middle line:84%
Now, once again, here's
a critical thing--

00:31:53.260 --> 00:31:55.120 align:middle line:90%
another big lesson for today.

00:31:55.120 --> 00:32:00.000 align:middle line:84%
We always have to think
about two views of evidence.

00:32:00.000 --> 00:32:02.920 align:middle line:90%
There's data and anecdote.

00:32:02.920 --> 00:32:05.980 align:middle line:84%
There are also plenty of
shitty charter schools.

00:32:05.980 --> 00:32:08.540 align:middle line:84%
If you're John Oliver fans,
he's the king of the anecdote.

00:32:08.540 --> 00:32:10.540 align:middle line:84%
If you saw John Oliver
piece on charter schools,

00:32:10.540 --> 00:32:12.748 align:middle line:84%
you think they're the worst
thing that ever happened.

00:32:12.748 --> 00:32:15.540 align:middle line:84%
It's because there
are some bad ones.

00:32:15.540 --> 00:32:18.620 align:middle line:84%
That's not the way we, as
social welfare maximizers,

00:32:18.620 --> 00:32:20.500 align:middle line:90%
should think about the problem.

00:32:20.500 --> 00:32:21.900 align:middle line:90%
I think he's hilarious guy.

00:32:21.900 --> 00:32:23.580 align:middle line:84%
But I've gotten
kind of sick of him,

00:32:23.580 --> 00:32:25.080 align:middle line:84%
because basically,
he's not thinking

00:32:25.080 --> 00:32:27.480 align:middle line:84%
about the way-- social impacts
should be in aggregate,

00:32:27.480 --> 00:32:28.360 align:middle line:90%
it's a good thing or not.

00:32:28.360 --> 00:32:30.460 align:middle line:84%
Now, there may be things you
can do to bring up the bottom.

00:32:30.460 --> 00:32:32.002 align:middle line:84%
The lessons of those
anecdotes, maybe

00:32:32.002 --> 00:32:33.580 align:middle line:90%
here's some regulations we need.

00:32:33.580 --> 00:32:36.300 align:middle line:84%
But you can't take those
anecdotes of some bad charter

00:32:36.300 --> 00:32:38.820 align:middle line:84%
schools and say we shouldn't
have charter schools.

00:32:38.820 --> 00:32:41.540 align:middle line:84%
Basically what that says is, we
need to change the regulations

00:32:41.540 --> 00:32:42.360 align:middle line:90%
around them.

00:32:42.360 --> 00:32:44.300 align:middle line:90%
But we deal in data.

00:32:44.300 --> 00:32:47.100 align:middle line:84%
And so for example,
my colleagues

00:32:47.100 --> 00:32:49.660 align:middle line:84%
have shown that the charter
school program in Louisiana

00:32:49.660 --> 00:32:50.500 align:middle line:90%
was not successful.

00:32:50.500 --> 00:32:53.000 align:middle line:84%
Here's a particular charter
school program that didn't work.

00:32:53.000 --> 00:32:55.660 align:middle line:84%
It didn't work because it
was badly run, et cetera.

00:32:55.660 --> 00:33:00.180 align:middle line:84%
So they're not always good,
but the bulk of the evidence

00:33:00.180 --> 00:33:01.980 align:middle line:90%
seems to be positive.

00:33:01.980 --> 00:33:06.300 align:middle line:84%
So that's the second
thing we've done.

00:33:06.300 --> 00:33:10.000 align:middle line:84%
So we've done two things to
try to fall short of vouchers,

00:33:10.000 --> 00:33:12.460 align:middle line:84%
but go in that direction,
which is, public school choice,

00:33:12.460 --> 00:33:14.040 align:middle line:90%
doesn't seem to really matter.

00:33:14.040 --> 00:33:16.520 align:middle line:84%
Allowing students these
quasi-public alternatives does

00:33:16.520 --> 00:33:17.620 align:middle line:90%
seem to be a good thing.

00:33:17.620 --> 00:33:20.280 align:middle line:90%


00:33:20.280 --> 00:33:23.120 align:middle line:84%
Finally, the last
thing we've done

00:33:23.120 --> 00:33:37.640 align:middle line:84%
is massively increased the way
we use testing and incentives

00:33:37.640 --> 00:33:40.760 align:middle line:90%
to reward and penalize schools.

00:33:40.760 --> 00:33:42.880 align:middle line:84%
So remember, I said
that the way schools are

00:33:42.880 --> 00:33:49.177 align:middle line:84%
financed is probably, like, 47%
state, 47% town, 5% federal.

00:33:49.177 --> 00:33:50.760 align:middle line:84%
Well, the federal
government, starting

00:33:50.760 --> 00:33:53.218 align:middle line:84%
with George Bush and the No
Child Left Behind Act, and then

00:33:53.218 --> 00:33:55.320 align:middle line:84%
subsequent
administrations as well,

00:33:55.320 --> 00:33:57.480 align:middle line:84%
has started to put more
of a thumb on the scale.

00:33:57.480 --> 00:33:59.420 align:middle line:84%
But the way they've
done it is said,

00:33:59.420 --> 00:34:01.925 align:middle line:84%
we're going to reward schools
based on their performance.

00:34:01.925 --> 00:34:03.800 align:middle line:84%
So it's been a massive
increase in the amount

00:34:03.800 --> 00:34:05.020 align:middle line:90%
of standardized testing.

00:34:05.020 --> 00:34:06.978 align:middle line:84%
You guys went to public
school, took a lot more

00:34:06.978 --> 00:34:08.693 align:middle line:90%
standardized tests than I did.

00:34:08.693 --> 00:34:10.610 align:middle line:84%
So the massive increased
standardized testing.

00:34:10.610 --> 00:34:14.290 align:middle line:84%
And that testing is being used
to reward or penalize schools.

00:34:14.290 --> 00:34:16.290 align:middle line:84%
So it's not quite the
"put them out of business"

00:34:16.290 --> 00:34:17.306 align:middle line:90%
model of vouchers.

00:34:17.306 --> 00:34:18.889 align:middle line:84%
But it is a little
bit take money away

00:34:18.889 --> 00:34:20.050 align:middle line:84%
from the schools
that are doing badly

00:34:20.050 --> 00:34:21.967 align:middle line:84%
and give money to schools
that are doing well.

00:34:21.967 --> 00:34:25.929 align:middle line:84%
It's like a smaller version
of this efficiency point.

00:34:25.929 --> 00:34:29.170 align:middle line:84%
So basically that's
caused a huge growth,

00:34:29.170 --> 00:34:33.370 align:middle line:84%
and once again, evidence
versus anecdote.

00:34:33.370 --> 00:34:34.889 align:middle line:84%
The evidence is
that overall, this

00:34:34.889 --> 00:34:38.570 align:middle line:84%
has been quite positive for
the US educational system.

00:34:38.570 --> 00:34:42.489 align:middle line:84%
Basically, overall
student outcomes

00:34:42.489 --> 00:34:46.210 align:middle line:84%
have improved from
this testing regime.

00:34:46.210 --> 00:34:51.290 align:middle line:84%
However, it's not been uniformly
positive in two senses.

00:34:51.290 --> 00:34:53.650 align:middle line:84%
First of all, if
you talk to anyone

00:34:53.650 --> 00:34:56.170 align:middle line:84%
from a high-quality
school district,

00:34:56.170 --> 00:34:57.702 align:middle line:90%
they'll say this is unnecessary.

00:34:57.702 --> 00:34:58.910 align:middle line:90%
Well, sure, it's unnecessary.

00:34:58.910 --> 00:35:00.978 align:middle line:84%
They're a high-quality
school district,

00:35:00.978 --> 00:35:02.770 align:middle line:84%
That's why it's the
disadvantaged kids that

00:35:02.770 --> 00:35:04.110 align:middle line:90%
benefit from charter schools.

00:35:04.110 --> 00:35:06.130 align:middle line:84%
This has really been
a change that's mostly

00:35:06.130 --> 00:35:07.490 align:middle line:90%
about bringing the bottom up.

00:35:07.490 --> 00:35:08.650 align:middle line:90%
It's not really helping the top.

00:35:08.650 --> 00:35:09.690 align:middle line:84%
They were already
providing good schools.

00:35:09.690 --> 00:35:10.927 align:middle line:90%
It's a pain in their ass.

00:35:10.927 --> 00:35:13.010 align:middle line:84%
So ideal system, you'd
figure who's a good school,

00:35:13.010 --> 00:35:18.230 align:middle line:84%
not put them in the system,
but you can't So that's

00:35:18.230 --> 00:35:19.170 align:middle line:90%
one complaint.

00:35:19.170 --> 00:35:20.830 align:middle line:84%
The other problem
is actually, there's

00:35:20.830 --> 00:35:24.630 align:middle line:84%
a whole literature on funky
ways people have tried

00:35:24.630 --> 00:35:26.710 align:middle line:90%
to get around these tests.

00:35:26.710 --> 00:35:32.330 align:middle line:84%
For example, I don't know
how many of you guys--

00:35:32.330 --> 00:35:34.330 align:middle line:84%
I hate to say this because
I'll hate the answer.

00:35:34.330 --> 00:35:36.455 align:middle line:84%
How many of you guys have
watched The Simpsons more

00:35:36.455 --> 00:35:38.970 align:middle line:90%
than 10 times?

00:35:38.970 --> 00:35:39.470 align:middle line:90%
Fuck.

00:35:39.470 --> 00:35:40.430 align:middle line:90%
[LAUGHTER]

00:35:40.430 --> 00:35:40.930 align:middle line:90%
People.

00:35:40.930 --> 00:35:44.270 align:middle line:84%
This is the most important show
in the history of television.

00:35:44.270 --> 00:35:47.830 align:middle line:84%
This is where you should get
your lessons today, your humor,

00:35:47.830 --> 00:35:49.730 align:middle line:90%
is from The Simpsons.

00:35:49.730 --> 00:35:50.230 align:middle line:90%
[LAUGHTER]

00:35:50.230 --> 00:35:52.230 align:middle line:84%
And The Simpsons
did a great episode,

00:35:52.230 --> 00:35:56.550 align:middle line:84%
which actually mirrors reality,
where it's tested at the school.

00:35:56.550 --> 00:35:58.990 align:middle line:84%
And they take a certain
set of kids like Bart

00:35:58.990 --> 00:36:00.730 align:middle line:84%
and say, hey, this
is a field trip.

00:36:00.730 --> 00:36:02.330 align:middle line:84%
And [INAUDIBLE] they just want
to take them out of the school,

00:36:02.330 --> 00:36:04.663 align:middle line:84%
so they don't take the test
to make the school look bad.

00:36:04.663 --> 00:36:06.210 align:middle line:90%
Turns out that actually happens.

00:36:06.210 --> 00:36:09.210 align:middle line:84%
Schools would raise the rate
at which they kick kids out

00:36:09.210 --> 00:36:11.432 align:middle line:84%
for disciplinary
problems on testing day.

00:36:11.432 --> 00:36:12.890 align:middle line:84%
So the kids who
were troublemakers,

00:36:12.890 --> 00:36:14.515 align:middle line:84%
do badly in the test,
wouldn't be there

00:36:14.515 --> 00:36:16.210 align:middle line:90%
and wouldn't take the test.

00:36:16.210 --> 00:36:18.850 align:middle line:84%
One of my favorite
papers on this-- schools

00:36:18.850 --> 00:36:20.890 align:middle line:84%
would actually
manipulate school menus

00:36:20.890 --> 00:36:23.890 align:middle line:84%
to sugar up the kids
right before tests.

00:36:23.890 --> 00:36:25.898 align:middle line:84%
Literally, they looked
at school menus.

00:36:25.898 --> 00:36:27.690 align:middle line:84%
And literally, the days
that certain grades

00:36:27.690 --> 00:36:30.410 align:middle line:84%
had tests, their school lunches
had more carbs and sugars

00:36:30.410 --> 00:36:32.930 align:middle line:90%
in them.

00:36:32.930 --> 00:36:34.190 align:middle line:90%
Now, those are cool studies.

00:36:34.190 --> 00:36:34.870 align:middle line:90%
I love them.

00:36:34.870 --> 00:36:37.370 align:middle line:84%
They don't mean testing
is a bad thing to do.

00:36:37.370 --> 00:36:41.810 align:middle line:84%
They just mean that there's
a trade-off to everything.

00:36:41.810 --> 00:36:43.310 align:middle line:84%
So there's been
these fun reactions.

00:36:43.310 --> 00:36:46.350 align:middle line:84%
But the bottom line is,
where does this leave us?

00:36:46.350 --> 00:36:48.930 align:middle line:84%
When I look at this whole
thing, where does it lead me?

00:36:48.930 --> 00:36:52.010 align:middle line:84%
Well, I guess the way I like to
think about it is the following.

00:36:52.010 --> 00:36:54.070 align:middle line:84%
Imagine that over
on this extreme,

00:36:54.070 --> 00:36:57.290 align:middle line:90%
we have no school choice.

00:36:57.290 --> 00:37:00.930 align:middle line:84%
And over in this extreme,
we have pure Chicago dream

00:37:00.930 --> 00:37:03.710 align:middle line:90%
vouchers.

00:37:03.710 --> 00:37:07.950 align:middle line:90%
US education has been here.

00:37:07.950 --> 00:37:10.950 align:middle line:90%
It's moving a bit to here.

00:37:10.950 --> 00:37:13.870 align:middle line:84%
All the evidence suggests
that's been positive,

00:37:13.870 --> 00:37:17.110 align:middle line:84%
which suggests continued
movement in this direction.

00:37:17.110 --> 00:37:18.757 align:middle line:90%
Should we go all the way here?

00:37:18.757 --> 00:37:20.090 align:middle line:90%
That's a pretty extreme outcome.

00:37:20.090 --> 00:37:21.890 align:middle line:84%
And I think we need more
evidence to see that.

00:37:21.890 --> 00:37:22.990 align:middle line:84%
But certainly the
existing evidence

00:37:22.990 --> 00:37:24.823 align:middle line:84%
says we should be moving
towards more school

00:37:24.823 --> 00:37:27.110 align:middle line:90%
choice along the way.

00:37:27.110 --> 00:37:28.770 align:middle line:84%
That would be my
read of the evidence.

00:37:28.770 --> 00:37:29.270 align:middle line:90%
Yeah.

00:37:29.270 --> 00:37:31.790 align:middle line:84%
AUDIENCE: [INAUDIBLE]
be properly read

00:37:31.790 --> 00:37:34.562 align:middle line:84%
as dishonest or more like
you're encouraging kids

00:37:34.562 --> 00:37:36.270 align:middle line:84%
to get more sleep
before a test or making

00:37:36.270 --> 00:37:37.312 align:middle line:90%
sure they're eating well?

00:37:37.312 --> 00:37:37.950 align:middle line:90%
JON GRUBER: No.

00:37:37.950 --> 00:37:40.510 align:middle line:84%
I mean, if kids should eat
well, they should eat well.

00:37:40.510 --> 00:37:42.503 align:middle line:84%
They shouldn't just
do it before a test.

00:37:42.503 --> 00:37:44.170 align:middle line:84%
So, no, I think that's
pretty dishonest.

00:37:44.170 --> 00:37:47.930 align:middle line:84%
Not dishonest, but
profit-maximizing,

00:37:47.930 --> 00:37:50.070 align:middle line:84%
which some people
called dishonest.

00:37:50.070 --> 00:37:53.630 align:middle line:84%
All right, so that's all
I want to say about that.

00:37:53.630 --> 00:37:55.830 align:middle line:84%
Let me go to the second
topic of the lecture,

00:37:55.830 --> 00:38:00.750 align:middle line:84%
which is the field that we
call "returns to education,"

00:38:00.750 --> 00:38:02.930 align:middle line:90%
which is a field of studying--

00:38:02.930 --> 00:38:07.385 align:middle line:84%
OK, we know we want government
involved in education.

00:38:07.385 --> 00:38:09.010 align:middle line:84%
But government
involvement in education

00:38:09.010 --> 00:38:09.950 align:middle line:90%
can mean lots of things.

00:38:09.950 --> 00:38:11.825 align:middle line:84%
In particular, how much
should the government

00:38:11.825 --> 00:38:13.850 align:middle line:90%
spend on education?

00:38:13.850 --> 00:38:16.890 align:middle line:84%
And that's going to depend
on what is the rate of return

00:38:16.890 --> 00:38:18.410 align:middle line:90%
to that investment.

00:38:18.410 --> 00:38:21.793 align:middle line:84%
Remember, government is always
doing cost-benefit analysis.

00:38:21.793 --> 00:38:23.210 align:middle line:84%
If the rate of
return to education

00:38:23.210 --> 00:38:25.043 align:middle line:84%
exceeds the rate at
which the government has

00:38:25.043 --> 00:38:27.790 align:middle line:84%
to spend to borrow the money,
it should make the investment.

00:38:27.790 --> 00:38:29.393 align:middle line:90%
If it doesn't, it shouldn't.

00:38:29.393 --> 00:38:30.810 align:middle line:84%
So the rate of
return to education

00:38:30.810 --> 00:38:32.490 align:middle line:84%
is a critical
parameter in thinking

00:38:32.490 --> 00:38:36.170 align:middle line:84%
about optimal
government involvement.

00:38:36.170 --> 00:38:39.210 align:middle line:84%
Now, the typical estimate--
this is a very rough.

00:38:39.210 --> 00:38:41.570 align:middle line:84%
typical estimate is that
another year of education

00:38:41.570 --> 00:38:44.650 align:middle line:90%
raises your earnings by 7%.

00:38:44.650 --> 00:38:46.750 align:middle line:84%
Every year of education,
you get a raise of 7%.

00:38:46.750 --> 00:38:47.795 align:middle line:90%
Now, that's not linear.

00:38:47.795 --> 00:38:49.170 align:middle line:84%
And obviously,
your MIT education

00:38:49.170 --> 00:38:50.910 align:middle line:84%
is different than
your other education.

00:38:50.910 --> 00:38:53.690 align:middle line:84%
But that's a number
to have in mind.

00:38:53.690 --> 00:38:56.970 align:middle line:84%
That would suggest a fairly high
rate of return to education.

00:38:56.970 --> 00:39:00.010 align:middle line:84%
A 7% boost in lifetime
earnings is pretty large

00:39:00.010 --> 00:39:04.310 align:middle line:84%
compared to the cost of
hiring another teacher.

00:39:04.310 --> 00:39:08.230 align:middle line:90%
However, we have a problem.

00:39:08.230 --> 00:39:11.390 align:middle line:84%
It's not clear how to
interpret that result.

00:39:11.390 --> 00:39:14.030 align:middle line:90%
There's two interpretations.

00:39:14.030 --> 00:39:19.150 align:middle line:84%
One interpretation, which is
called the "human capital view,"

00:39:19.150 --> 00:39:22.390 align:middle line:84%
is that people
are like machines.

00:39:22.390 --> 00:39:24.290 align:middle line:84%
And just like as we
spend more in a machine,

00:39:24.290 --> 00:39:25.393 align:middle line:90%
we get more capital.

00:39:25.393 --> 00:39:26.810 align:middle line:84%
If we spend more
educating people,

00:39:26.810 --> 00:39:28.335 align:middle line:90%
we get more human capital.

00:39:28.335 --> 00:39:30.710 align:middle line:84%
The more we spend in your
education, the more the smarter

00:39:30.710 --> 00:39:32.350 align:middle line:84%
you are, the more
productive you are,

00:39:32.350 --> 00:39:34.600 align:middle line:84%
the more you're producing
valuable things for society.

00:39:34.600 --> 00:39:37.470 align:middle line:84%
In other words, we are raising
your marginal product of labor.

00:39:37.470 --> 00:39:40.690 align:middle line:84%
So there's a 7% rise
in not just your wage,

00:39:40.690 --> 00:39:42.210 align:middle line:84%
but your marginal
product of labor.

00:39:42.210 --> 00:39:43.870 align:middle line:84%
That's why your
wage is going up.

00:39:43.870 --> 00:39:45.230 align:middle line:84%
Your marginal product
of labor is actually

00:39:45.230 --> 00:39:46.570 align:middle line:84%
your value, marginal
product of labor.

00:39:46.570 --> 00:39:48.028 align:middle line:84%
It's the value of
what you produce.

00:39:48.028 --> 00:39:49.710 align:middle line:84%
And that's why
you get paid more.

00:39:49.710 --> 00:39:52.030 align:middle line:84%
That would be the
human capital view.

00:39:52.030 --> 00:39:55.190 align:middle line:84%
But the evidence that
people are more educated

00:39:55.190 --> 00:39:58.390 align:middle line:84%
are paid more is absolutely
consistent with another story,

00:39:58.390 --> 00:39:59.910 align:middle line:90%
which is the screening story.

00:39:59.910 --> 00:40:02.450 align:middle line:90%


00:40:02.450 --> 00:40:06.770 align:middle line:84%
Let's say that the way all
educational systems worked

00:40:06.770 --> 00:40:09.850 align:middle line:84%
is they consisted of
memorizing baseball statistics.

00:40:09.850 --> 00:40:12.917 align:middle line:84%
And let us posit that memorizing
baseball statistics is totally

00:40:12.917 --> 00:40:15.250 align:middle line:84%
irrelevant to producing what
you're all going to produce

00:40:15.250 --> 00:40:17.167 align:middle line:84%
in your jobs. [? It's ?]
[? not ?] [? easy, ?]

00:40:17.167 --> 00:40:19.010 align:middle line:90%
but let's imagine it is.

00:40:19.010 --> 00:40:21.757 align:middle line:84%
And furthermore, let's say that
how far you get in education

00:40:21.757 --> 00:40:24.090 align:middle line:84%
is determined by how good you
are at memorizing baseball

00:40:24.090 --> 00:40:26.250 align:middle line:90%
statistics.

00:40:26.250 --> 00:40:29.250 align:middle line:84%
You will find that the people
who get the most education

00:40:29.250 --> 00:40:31.390 align:middle line:90%
earn the most.

00:40:31.390 --> 00:40:31.890 align:middle line:90%
Why?

00:40:31.890 --> 00:40:34.515 align:middle line:84%
Because the smartest people are
the best at memorizing baseball

00:40:34.515 --> 00:40:36.090 align:middle line:90%
statistics.

00:40:36.090 --> 00:40:38.910 align:middle line:84%
So they go on the most
and they earn the most.

00:40:38.910 --> 00:40:41.158 align:middle line:84%
But you didn't actually
learn anything in school.

00:40:41.158 --> 00:40:43.450 align:middle line:84%
School just separated people
who are good at memorizing

00:40:43.450 --> 00:40:45.665 align:middle line:84%
statistics from
those who aren't.

00:40:45.665 --> 00:40:47.790 align:middle line:84%
So you didn't raise your
marginal product of labor.

00:40:47.790 --> 00:40:51.170 align:middle line:84%
It didn't make you any
better at making computers.

00:40:51.170 --> 00:40:54.490 align:middle line:84%
It just was a way of screening
out who was smart and who

00:40:54.490 --> 00:40:56.050 align:middle line:90%
wasn't.

00:40:56.050 --> 00:40:58.300 align:middle line:84%
The problem is that
would also show

00:40:58.300 --> 00:41:01.240 align:middle line:84%
that those with higher
education would earn more.

00:41:01.240 --> 00:41:01.740 align:middle line:90%
Why?

00:41:01.740 --> 00:41:03.940 align:middle line:84%
Because what you're
doing is actually,

00:41:03.940 --> 00:41:06.140 align:middle line:84%
if we go back to
chapter 3 terms,

00:41:06.140 --> 00:41:09.580 align:middle line:84%
there's an omitted bias
in our regressions.

00:41:09.580 --> 00:41:13.560 align:middle line:84%
We regress education on years of
earnings, on years of education.

00:41:13.560 --> 00:41:16.140 align:middle line:84%
There's an omitted
variable, called ability.

00:41:16.140 --> 00:41:18.860 align:middle line:84%
And ability is correlated
with both what you earn

00:41:18.860 --> 00:41:20.700 align:middle line:84%
and how many years
of education you get.

00:41:20.700 --> 00:41:21.920 align:middle line:90%
So we have a non-comparable.

00:41:21.920 --> 00:41:24.420 align:middle line:84%
The treatment group that
got more education is not

00:41:24.420 --> 00:41:27.167 align:middle line:84%
comparable to the control
group that got less education,

00:41:27.167 --> 00:41:29.500 align:middle line:84%
as well as you can't just
compare them and say education

00:41:29.500 --> 00:41:30.760 align:middle line:90%
improved your human capital.

00:41:30.760 --> 00:41:31.260 align:middle line:90%
Yeah.

00:41:31.260 --> 00:41:33.020 align:middle line:84%
AUDIENCE: Is
screening [INAUDIBLE]

00:41:33.020 --> 00:41:35.268 align:middle line:84%
if it's a more efficient
way of helping people

00:41:35.268 --> 00:41:37.060 align:middle line:84%
navigate their way
through the labor market

00:41:37.060 --> 00:41:41.100 align:middle line:84%
to jobs where they're
actually, like, [INAUDIBLE]?

00:41:41.100 --> 00:41:43.460 align:middle line:84%
JON GRUBER: Screening,
could be valuable.

00:41:43.460 --> 00:41:45.700 align:middle line:84%
The point is, it's
not clear that you'd

00:41:45.700 --> 00:41:48.180 align:middle line:84%
want to spend 35% of the entire
state and local government

00:41:48.180 --> 00:41:49.847 align:middle line:84%
budget in the US
helping people navigate

00:41:49.847 --> 00:41:51.740 align:middle line:90%
which job is best for them.

00:41:51.740 --> 00:41:56.260 align:middle line:84%
We could probably have a
lot more efficient system.

00:41:56.260 --> 00:41:58.243 align:middle line:84%
In other words, the
other name for screening

00:41:58.243 --> 00:41:59.660 align:middle line:84%
is called Harvard
Business School.

00:41:59.660 --> 00:42:01.660 align:middle line:90%
[LAUGHTER]

00:42:01.660 --> 00:42:03.160 align:middle line:90%
You don't learn anything.

00:42:03.160 --> 00:42:07.760 align:middle line:84%
But basically, people who go
to Harvard Business School

00:42:07.760 --> 00:42:08.880 align:middle line:90%
are the cream of the crop.

00:42:08.880 --> 00:42:09.380 align:middle line:90%
They get in.

00:42:09.380 --> 00:42:11.422 align:middle line:84%
They have a great way of
finding the best people.

00:42:11.422 --> 00:42:13.300 align:middle line:84%
Now, it's not true
it's not productive.

00:42:13.300 --> 00:42:15.260 align:middle line:84%
It's productive mostly
making connections.

00:42:15.260 --> 00:42:16.660 align:middle line:90%
I'm being extreme, obviously.

00:42:16.660 --> 00:42:20.060 align:middle line:84%
But the point is that basically,
these are two different views.

00:42:20.060 --> 00:42:21.300 align:middle line:90%
How do you distinguish them?

00:42:21.300 --> 00:42:23.800 align:middle line:84%
Well, you distinguish them
using the tools of chapter 3

00:42:23.800 --> 00:42:26.972 align:middle line:84%
to develop experimental or
quasi-experimental methods

00:42:26.972 --> 00:42:28.680 align:middle line:84%
to look at what happens
when you randomly

00:42:28.680 --> 00:42:30.720 align:middle line:90%
give some more education.

00:42:30.720 --> 00:42:35.560 align:middle line:84%
And there's a massive literature
replete with incredibly clever

00:42:35.560 --> 00:42:36.678 align:middle line:90%
approaches.

00:42:36.678 --> 00:42:38.720 align:middle line:84%
So one approach, my Nobel
Prize-winning colleague

00:42:38.720 --> 00:42:41.478 align:middle line:84%
Esther Duflo, in her
thesis, she looked

00:42:41.478 --> 00:42:43.520 align:middle line:84%
at what happened when the
government of Indonesia

00:42:43.520 --> 00:42:45.270 align:middle line:84%
randomly built a bunch
more schools in one

00:42:45.270 --> 00:42:46.800 align:middle line:90%
place than another.

00:42:46.800 --> 00:42:48.360 align:middle line:90%
The two places were identical.

00:42:48.360 --> 00:42:50.017 align:middle line:84%
One got more
schools, one didn't.

00:42:50.017 --> 00:42:51.600 align:middle line:84%
She found that years
later, the ones--

00:42:51.600 --> 00:42:53.183 align:middle line:84%
place that got more
schools, that kids

00:42:53.183 --> 00:42:54.440 align:middle line:90%
were earning a lot more.

00:42:54.440 --> 00:42:57.460 align:middle line:84%
That's evidence it was a
human capital improvement.

00:42:57.460 --> 00:43:00.340 align:middle line:84%
Another great study is
by Adriana Ileras-Muney

00:43:00.340 --> 00:43:02.060 align:middle line:90%
out at UCLA.

00:43:02.060 --> 00:43:05.980 align:middle line:84%
In the early 1900s in the
US, kids didn't have to go

00:43:05.980 --> 00:43:06.940 align:middle line:90%
to school.

00:43:06.940 --> 00:43:09.680 align:middle line:84%
And then they put in
minimum school-leaving ages.

00:43:09.680 --> 00:43:12.660 align:middle line:90%
But these ages varied by state.

00:43:12.660 --> 00:43:17.060 align:middle line:84%
So compare two 17-year-olds one
who's in a state where you have

00:43:17.060 --> 00:43:20.060 align:middle line:84%
to go to school till you're 17,
and one a state where you can

00:43:20.060 --> 00:43:21.517 align:middle line:90%
leave when you're 16?

00:43:21.517 --> 00:43:23.100 align:middle line:84%
Well, the only
difference between them

00:43:23.100 --> 00:43:25.380 align:middle line:84%
is one was forced to stay
in school one more year.

00:43:25.380 --> 00:43:26.960 align:middle line:90%
Do they earn more later in life?

00:43:26.960 --> 00:43:28.540 align:middle line:90%
The answer is yes.

00:43:28.540 --> 00:43:31.620 align:middle line:84%
So there's a lot of evidence
for the human capital story.

00:43:31.620 --> 00:43:33.920 align:middle line:84%
There is some evidence
for the screening story.

00:43:33.920 --> 00:43:40.780 align:middle line:90%


00:43:40.780 --> 00:43:43.640 align:middle line:84%
Basically, there was this
great study in Sweden,

00:43:43.640 --> 00:43:46.500 align:middle line:84%
where they found that
teachers discretionarily

00:43:46.500 --> 00:43:48.798 align:middle line:84%
were moving students from
not passing to passing.

00:43:48.798 --> 00:43:51.340 align:middle line:84%
And they could look at teachers
who were using the discretion

00:43:51.340 --> 00:43:53.640 align:middle line:84%
to move students and
those who weren't.

00:43:53.640 --> 00:43:55.460 align:middle line:90%
Now, it was the same score.

00:43:55.460 --> 00:43:56.840 align:middle line:90%
Let me back up.

00:43:56.840 --> 00:43:59.060 align:middle line:84%
You had two students,
same score on the test.

00:43:59.060 --> 00:44:00.860 align:middle line:84%
One's with the teacher
that's a soft heart.

00:44:00.860 --> 00:44:02.700 align:middle line:84%
And she'd pass a
lot more students.

00:44:02.700 --> 00:44:05.920 align:middle line:84%
The other teacher was a hard ass
and wouldn't pass the students.

00:44:05.920 --> 00:44:08.000 align:middle line:84%
Those students had the
same human capital,

00:44:08.000 --> 00:44:10.107 align:middle line:84%
but the ones who passed
earned a lot more.

00:44:10.107 --> 00:44:12.440 align:middle line:84%
So that suggests, well, there
is some screening function

00:44:12.440 --> 00:44:13.560 align:middle line:90%
here too.

00:44:13.560 --> 00:44:15.163 align:middle line:90%
So both are operating.

00:44:15.163 --> 00:44:16.580 align:middle line:84%
But primarily,
it's human capital.

00:44:16.580 --> 00:44:21.100 align:middle line:84%
There is a real return
to more education

00:44:21.100 --> 00:44:23.520 align:middle line:84%
There is a real return
to more education.

00:44:23.520 --> 00:44:26.080 align:middle line:90%
Now, let me stop there.

00:44:26.080 --> 00:44:29.720 align:middle line:84%
Does the fact that there is a
high rate of return to education

00:44:29.720 --> 00:44:33.360 align:middle line:84%
mean the government
should invest in it?

00:44:33.360 --> 00:44:34.672 align:middle line:90%
Why not necessarily?

00:44:34.672 --> 00:44:36.880 align:middle line:84%
Let's say that it's true
that every year of education

00:44:36.880 --> 00:44:38.957 align:middle line:90%
makes earnings 7% higher.

00:44:38.957 --> 00:44:41.040 align:middle line:84%
Why should that necessarily
justify the government

00:44:41.040 --> 00:44:43.960 align:middle line:90%
getting involved?

00:44:43.960 --> 00:44:44.460 align:middle line:90%
Yeah.

00:44:44.460 --> 00:44:45.572 align:middle line:90%
AUDIENCE: It could be--

00:44:45.572 --> 00:44:48.280 align:middle line:84%
it could be the externalities in
that your marginal product could

00:44:48.280 --> 00:44:50.340 align:middle line:84%
go up by more than
7% in [? taxes. ?]

00:44:50.340 --> 00:44:52.905 align:middle line:84%
JON GRUBER: Well, no,
you made it too hard.

00:44:52.905 --> 00:44:54.280 align:middle line:84%
Let's say there's
no externality.

00:44:54.280 --> 00:44:56.165 align:middle line:84%
Then the government
shouldn't get involved.

00:44:56.165 --> 00:44:57.540 align:middle line:84%
I mean, basically,
the government

00:44:57.540 --> 00:45:00.285 align:middle line:84%
should say, look, I
should just-- why should I

00:45:00.285 --> 00:45:01.160 align:middle line:90%
bribe public schools?

00:45:01.160 --> 00:45:03.660 align:middle line:84%
I should just give
loans to everybody.

00:45:03.660 --> 00:45:06.683 align:middle line:84%
If basically, all I'm doing
is increasing your wages,

00:45:06.683 --> 00:45:08.100 align:middle line:84%
what's the case
for the government

00:45:08.100 --> 00:45:09.660 align:middle line:90%
to invest money in this?

00:45:09.660 --> 00:45:11.340 align:middle line:84%
Now, there's a case for all
the other reasons-- making

00:45:11.340 --> 00:45:14.007 align:middle line:84%
sure you're a good citizen, that
you don't commit crimes, things

00:45:14.007 --> 00:45:14.560 align:middle line:90%
like that.

00:45:14.560 --> 00:45:16.380 align:middle line:84%
But basically, if
literally all education

00:45:16.380 --> 00:45:18.660 align:middle line:84%
is doing-- so once again,
let's imagine education

00:45:18.660 --> 00:45:20.758 align:middle line:84%
through ninth grade is
making you a good citizen,

00:45:20.758 --> 00:45:21.800 align:middle line:90%
makes you don't do crime.

00:45:21.800 --> 00:45:23.420 align:middle line:84%
Let's imagine all this stuff
in high school beyond it's

00:45:23.420 --> 00:45:25.100 align:middle line:84%
just about increasing
your wages.

00:45:25.100 --> 00:45:27.140 align:middle line:84%
Then the government
shouldn't be doing it.

00:45:27.140 --> 00:45:28.820 align:middle line:84%
The government
should make it easier

00:45:28.820 --> 00:45:31.320 align:middle line:84%
for you to do it, address
the credit market failures,

00:45:31.320 --> 00:45:33.740 align:middle line:90%
address the parental failures.

00:45:33.740 --> 00:45:35.260 align:middle line:84%
But the government,
unless there's

00:45:35.260 --> 00:45:38.500 align:middle line:84%
an externality, an
effect on others,

00:45:38.500 --> 00:45:40.343 align:middle line:84%
the government
shouldn't be doing it.

00:45:40.343 --> 00:45:42.760 align:middle line:84%
So the question is, are there
externalities for education?

00:45:42.760 --> 00:45:45.468 align:middle line:84%
And the answer is there's been a
huge literature which has shown,

00:45:45.468 --> 00:45:47.820 align:middle line:84%
yes, education
leads to less crime.

00:45:47.820 --> 00:45:51.400 align:middle line:84%
Education leads to better health
for you and your children.

00:45:51.400 --> 00:45:54.000 align:middle line:84%
Education leads to more
informed voting and higher voter

00:45:54.000 --> 00:45:55.440 align:middle line:90%
participation.

00:45:55.440 --> 00:45:58.480 align:middle line:84%
There's a lot of studies which
show that education matters.

00:45:58.480 --> 00:46:00.200 align:middle line:90%
It raises wages.

00:46:00.200 --> 00:46:03.720 align:middle line:84%
But also, education has
productivity spillovers.

00:46:03.720 --> 00:46:07.120 align:middle line:84%
If you're around more educated
people, you yourself earn more.

00:46:07.120 --> 00:46:09.960 align:middle line:84%
So there's clearly massive
positive externalities

00:46:09.960 --> 00:46:11.160 align:middle line:90%
for education.

00:46:11.160 --> 00:46:13.560 align:middle line:84%
So the return is
positive, not just

00:46:13.560 --> 00:46:17.760 align:middle line:84%
privately for the individuals,
but publicly for society too.

00:46:17.760 --> 00:46:23.480 align:middle line:84%
Now, that says we should
invest in education.

00:46:23.480 --> 00:46:26.120 align:middle line:84%
But the question then
is, do we invest in that

00:46:26.120 --> 00:46:28.560 align:middle line:84%
by just letting people
go to school more?

00:46:28.560 --> 00:46:32.280 align:middle line:84%
Or should we actually care about
the quality of those schools?

00:46:32.280 --> 00:46:35.480 align:middle line:84%
How should we measure whether
better schools actually

00:46:35.480 --> 00:46:37.760 align:middle line:84%
lead to better student
outcomes, as opposed

00:46:37.760 --> 00:46:38.802 align:middle line:90%
to just getting educated?

00:46:38.802 --> 00:46:41.218 align:middle line:84%
We've just said getting educated
leads to better outcomes.

00:46:41.218 --> 00:46:43.100 align:middle line:84%
People go to school
commit less crimes.

00:46:43.100 --> 00:46:44.420 align:middle line:84%
People who go to
school are healthier.

00:46:44.420 --> 00:46:45.837 align:middle line:84%
People who go to
school earn more.

00:46:45.837 --> 00:46:48.600 align:middle line:84%
But there's going to school
and there's going to school.

00:46:48.600 --> 00:46:51.960 align:middle line:84%
There's a rich private school
and a crappy public school.

00:46:51.960 --> 00:46:53.280 align:middle line:90%
We just said going to school.

00:46:53.280 --> 00:46:54.840 align:middle line:84%
What about the
quality dimension?

00:46:54.840 --> 00:46:56.780 align:middle line:90%
How much does that matter?

00:46:56.780 --> 00:47:01.220 align:middle line:84%
And here, once again,
there's been an enormous body

00:47:01.220 --> 00:47:04.900 align:middle line:84%
of work looking at this,
looking at things like teacher

00:47:04.900 --> 00:47:06.883 align:middle line:90%
salaries and class size.

00:47:06.883 --> 00:47:08.300 align:middle line:84%
One of most
interesting literature

00:47:08.300 --> 00:47:11.745 align:middle line:84%
has been on class size,
where basically, this

00:47:11.745 --> 00:47:14.120 align:middle line:84%
is in some sense, a little
bit of a weakness of my field.

00:47:14.120 --> 00:47:15.820 align:middle line:90%
I think, if I can be honest.

00:47:15.820 --> 00:47:17.940 align:middle line:84%
For years there was
this view, well,

00:47:17.940 --> 00:47:20.440 align:middle line:84%
we don't have good evidence
that smaller class size matters,

00:47:20.440 --> 00:47:21.800 align:middle line:90%
so we shouldn't care about it.

00:47:21.800 --> 00:47:22.960 align:middle line:84%
But if you ask
those same people,

00:47:22.960 --> 00:47:25.127 align:middle line:84%
do you want your kids in a
big class or small class,

00:47:25.127 --> 00:47:26.480 align:middle line:90%
they'd say a small class.

00:47:26.480 --> 00:47:27.600 align:middle line:90%
We knew it mattered.

00:47:27.600 --> 00:47:30.140 align:middle line:84%
We just hadn't come up with a
convincing way to get at it.

00:47:30.140 --> 00:47:32.640 align:middle line:84%
It's not like we didn't
think it mattered.

00:47:32.640 --> 00:47:33.560 align:middle line:90%
We knew it mattered.

00:47:33.560 --> 00:47:35.935 align:middle line:84%
We tried to come up with a
convincing way to but we have.

00:47:35.935 --> 00:47:38.400 align:middle line:84%
And there's been a number
of fascinating studies.

00:47:38.400 --> 00:47:41.580 align:middle line:84%
One really cool study, once
again by Josh Angrist--

00:47:41.580 --> 00:47:44.500 align:middle line:84%
in Israel, they follow
the biblical rule

00:47:44.500 --> 00:47:46.220 align:middle line:90%
called Maimonides law.

00:47:46.220 --> 00:47:48.760 align:middle line:84%
And Maimonides law says
there is a certain number

00:47:48.760 --> 00:47:52.320 align:middle line:84%
of kids, which is the biggest
a classroom should be.

00:47:52.320 --> 00:47:55.340 align:middle line:84%
And when your cohort size
exceeds that number by one,

00:47:55.340 --> 00:47:56.715 align:middle line:90%
they split you into two classes.

00:47:56.715 --> 00:47:58.840 align:middle line:84%
It's a random cutoff that
determines whether you're

00:47:58.840 --> 00:48:00.090 align:middle line:90%
in a big class or small class.

00:48:00.090 --> 00:48:02.900 align:middle line:84%
If your cutoff is one below that
number, you're in a big class.

00:48:02.900 --> 00:48:04.600 align:middle line:84%
If you're one above that
number, you're in a small class

00:48:04.600 --> 00:48:06.047 align:middle line:90%
because they split into two.

00:48:06.047 --> 00:48:07.880 align:middle line:84%
And he finds that being
in the smaller class

00:48:07.880 --> 00:48:09.960 align:middle line:90%
improves your outcomes.

00:48:09.960 --> 00:48:11.495 align:middle line:90%
There's also real trials.

00:48:11.495 --> 00:48:14.120 align:middle line:84%
There was something called the
Tennessee STAR experiment, where

00:48:14.120 --> 00:48:17.800 align:middle line:84%
they literally randomized kids
across class sizes in Tennessee.

00:48:17.800 --> 00:48:23.605 align:middle line:84%
And they found the kids who were
in smaller classes did better,

00:48:23.605 --> 00:48:25.980 align:middle line:84%
not only in the short run,
but actually, in the long run.

00:48:25.980 --> 00:48:27.440 align:middle line:84%
They followed those kids up
and looked at their earnings

00:48:27.440 --> 00:48:29.700 align:middle line:84%
later in life, and
they earned more.

00:48:29.700 --> 00:48:31.800 align:middle line:90%
So it's really powerful.

00:48:31.800 --> 00:48:34.640 align:middle line:84%
Here's a fascinating
fact, though.

00:48:34.640 --> 00:48:40.400 align:middle line:84%
California, in 1996, passed a
law mandating a maximum class

00:48:40.400 --> 00:48:43.178 align:middle line:84%
size, which would be justified
based on this evidence.

00:48:43.178 --> 00:48:44.720 align:middle line:84%
So they basically
said the class size

00:48:44.720 --> 00:48:48.290 align:middle line:84%
had to be reduced
to no more than 20

00:48:48.290 --> 00:48:50.210 align:middle line:90%
a year for grades K to 3.

00:48:50.210 --> 00:48:53.130 align:middle line:84%
It cost the state $1
billion to do this.

00:48:53.130 --> 00:48:55.490 align:middle line:84%
And studies of it
found that it did not

00:48:55.490 --> 00:48:58.050 align:middle line:90%
improve student outcomes.

00:48:58.050 --> 00:49:00.050 align:middle line:84%
Now, this is very
strange, but it's

00:49:00.050 --> 00:49:02.770 align:middle line:84%
a perfect example of
partial equilibrium

00:49:02.770 --> 00:49:05.530 align:middle line:84%
versus general
equilibrium economics.

00:49:05.530 --> 00:49:09.068 align:middle line:84%
Holding all else constant, is
smaller classes good for you.

00:49:09.068 --> 00:49:11.110 align:middle line:84%
But now let's say you're
the state of California.

00:49:11.110 --> 00:49:12.350 align:middle line:90%
You're a city in California.

00:49:12.350 --> 00:49:15.730 align:middle line:84%
You've just been told you have
to overnight, or very rapidly,

00:49:15.730 --> 00:49:17.450 align:middle line:90%
reduce your class sizes.

00:49:17.450 --> 00:49:18.690 align:middle line:90%
What do you do?

00:49:18.690 --> 00:49:20.370 align:middle line:90%
You hire crappy teachers.

00:49:20.370 --> 00:49:22.690 align:middle line:84%
You put the first and
second grade together

00:49:22.690 --> 00:49:24.270 align:middle line:84%
so you can split
them more equally,

00:49:24.270 --> 00:49:26.478 align:middle line:84%
which has actually been
shown to be bad educationally

00:49:26.478 --> 00:49:27.490 align:middle line:90%
to mixed grades.

00:49:27.490 --> 00:49:29.650 align:middle line:84%
You do a bunch of stuff to
meet this mandate, which

00:49:29.650 --> 00:49:32.067 align:middle line:84%
is reducing class size through
other actions which are not

00:49:32.067 --> 00:49:33.950 align:middle line:90%
productive for education.

00:49:33.950 --> 00:49:35.450 align:middle line:84%
So this is a
fascinating example of,

00:49:35.450 --> 00:49:37.367 align:middle line:84%
when we think about
government policy changes,

00:49:37.367 --> 00:49:39.450 align:middle line:84%
we have to think about
all the reactions to them.

00:49:39.450 --> 00:49:41.242 align:middle line:84%
And while the evidence
says smaller classes

00:49:41.242 --> 00:49:43.090 align:middle line:84%
are better, simply
mandating California

00:49:43.090 --> 00:49:45.423 align:middle line:84%
to have smaller classes without
putting the resources in

00:49:45.423 --> 00:49:48.430 align:middle line:84%
to make it feasible
led to actually not

00:49:48.430 --> 00:49:49.830 align:middle line:90%
an improvement in outcomes.

00:49:49.830 --> 00:49:50.990 align:middle line:90%
Yeah.

00:49:50.990 --> 00:49:53.550 align:middle line:84%
AUDIENCE: I have a question
about the [INAUDIBLE].

00:49:53.550 --> 00:49:55.510 align:middle line:84%
Is the evidence
about the class sizes

00:49:55.510 --> 00:49:58.710 align:middle line:84%
or about the
teacher-student ratios?

00:49:58.710 --> 00:50:00.210 align:middle line:84%
JON GRUBER: That's
a great question.

00:50:00.210 --> 00:50:02.910 align:middle line:84%
I think it's typically viewed
as teacher-student ratio.

00:50:02.910 --> 00:50:05.790 align:middle line:90%
Yeah.

00:50:05.790 --> 00:50:06.550 align:middle line:90%
All right?

00:50:06.550 --> 00:50:09.010 align:middle line:84%
So once again, where
are we in education?

00:50:09.010 --> 00:50:11.747 align:middle line:84%
First of all government
should be involved.

00:50:11.747 --> 00:50:13.330 align:middle line:84%
How should the
government be involved?

00:50:13.330 --> 00:50:14.830 align:middle line:84%
Well, basically,
there's a trade-off

00:50:14.830 --> 00:50:16.410 align:middle line:90%
with how much choice to leave.

00:50:16.410 --> 00:50:18.410 align:middle line:84%
My view is there probably
should be more choice,

00:50:18.410 --> 00:50:20.630 align:middle line:90%
but we understand the trade-off.

00:50:20.630 --> 00:50:25.330 align:middle line:84%
Then the question is, well, is
investing education worth it?

00:50:25.330 --> 00:50:26.710 align:middle line:90%
The answer is yes.

00:50:26.710 --> 00:50:29.210 align:middle line:84%
Is investing in higher
quality education worth it?

00:50:29.210 --> 00:50:32.350 align:middle line:90%
The answer is yes.

00:50:32.350 --> 00:50:35.110 align:middle line:84%
And that's where we are,
except for one topic, which

00:50:35.110 --> 00:50:36.730 align:middle line:84%
is a little bit
germane to all of you,

00:50:36.730 --> 00:50:38.130 align:middle line:90%
which is higher education.

00:50:38.130 --> 00:50:41.350 align:middle line:84%
And that's what I spend
the last 25 minutes on,

00:50:41.350 --> 00:50:43.497 align:middle line:84%
which is the system
of higher education,

00:50:43.497 --> 00:50:44.830 align:middle line:90%
particularly focusing on the US.

00:50:44.830 --> 00:50:47.210 align:middle line:84%
The reason I'm focusing
on the US in particular

00:50:47.210 --> 00:50:49.590 align:middle line:84%
is that we are by far
the best in the world.

00:50:49.590 --> 00:50:59.170 align:middle line:84%
The US, every year, 1.2
million foreign students

00:50:59.170 --> 00:51:01.890 align:middle line:84%
a year spend more
than $39 billion

00:51:01.890 --> 00:51:03.690 align:middle line:90%
to enroll in American colleges.

00:51:03.690 --> 00:51:06.750 align:middle line:84%
At the same time, 60,000
Americans study abroad,

00:51:06.750 --> 00:51:09.450 align:middle line:84%
typically just to
go party in Europe.

00:51:09.450 --> 00:51:12.210 align:middle line:84%
So basically, the
market has spoken.

00:51:12.210 --> 00:51:16.810 align:middle line:84%
And we have by far the world's
best higher education system.

00:51:16.810 --> 00:51:18.990 align:middle line:84%
And if you are a
free market advocate,

00:51:18.990 --> 00:51:22.210 align:middle line:84%
you say, well, here's
an interesting fact.

00:51:22.210 --> 00:51:27.490 align:middle line:84%
If you look at non-higher
education, we are terrible.

00:51:27.490 --> 00:51:29.150 align:middle line:84%
We're way down in
world rankings.

00:51:29.150 --> 00:51:31.570 align:middle line:90%
90% of it is public.

00:51:31.570 --> 00:51:35.970 align:middle line:84%
If you look at
higher education--

00:51:35.970 --> 00:51:41.190 align:middle line:84%
if you look at higher
education, 40% of it is private.

00:51:41.190 --> 00:51:43.430 align:middle line:90%
Only 60% is public.

00:51:43.430 --> 00:51:45.450 align:middle line:84%
So here's an interesting
pair of facts.

00:51:45.450 --> 00:51:47.350 align:middle line:84%
The system where we're
the best in the world

00:51:47.350 --> 00:51:49.030 align:middle line:90%
is where we have 40% private.

00:51:49.030 --> 00:51:51.690 align:middle line:84%
The system where we're one
of the worst in the world's

00:51:51.690 --> 00:51:55.830 align:middle line:84%
where we're less
than 10% private.

00:51:55.830 --> 00:51:57.870 align:middle line:84%
So that suggests that
gee, maybe competition

00:51:57.870 --> 00:52:00.010 align:middle line:84%
and private incentives,
there's something to it.

00:52:00.010 --> 00:52:01.250 align:middle line:84%
Now, I wanted more
to say about that.

00:52:01.250 --> 00:52:02.792 align:middle line:84%
It's just an
interesting observation.

00:52:02.792 --> 00:52:04.715 align:middle line:84%
It's not obviously
the reason we're best

00:52:04.715 --> 00:52:06.090 align:middle line:84%
in the world at
higher education.

00:52:06.090 --> 00:52:07.830 align:middle line:84%
But it is an
interesting observation

00:52:07.830 --> 00:52:14.568 align:middle line:84%
that where we have more
private sector involvement,

00:52:14.568 --> 00:52:16.110 align:middle line:84%
we're doing better,
at least relative

00:52:16.110 --> 00:52:18.430 align:middle line:90%
to the rest of the world.

00:52:18.430 --> 00:52:21.670 align:middle line:84%
Now, what is the government's
role in higher education?

00:52:21.670 --> 00:52:23.430 align:middle line:84%
Now, once again, here,
we have to go back

00:52:23.430 --> 00:52:24.830 align:middle line:90%
to the first question.

00:52:24.830 --> 00:52:27.250 align:middle line:84%
It's not as obvious the
government should be involved.

00:52:27.250 --> 00:52:30.018 align:middle line:84%
I mean, all our
citizenship stuff

00:52:30.018 --> 00:52:31.310 align:middle line:90%
should have been taken care of.

00:52:31.310 --> 00:52:33.602 align:middle line:84%
Our crime stuff should have
been taken care, et cetera.

00:52:33.602 --> 00:52:35.727 align:middle line:84%
So it's not entirely clear
the government should be

00:52:35.727 --> 00:52:36.970 align:middle line:90%
involved in higher education.

00:52:36.970 --> 00:52:42.090 align:middle line:84%
Indeed, what is the main market
failure with higher education?

00:52:42.090 --> 00:52:45.830 align:middle line:84%
The main market failure
is credit market failures.

00:52:45.830 --> 00:52:48.047 align:middle line:84%
It is the fact that in
principle, in a perfect world,

00:52:48.047 --> 00:52:50.630 align:middle line:84%
we'd say, look, we're going to
educate you through 12th grade.

00:52:50.630 --> 00:52:51.590 align:middle line:90%
You want to go on, that's great.

00:52:51.590 --> 00:52:52.870 align:middle line:90%
Just take a loan and go on.

00:52:52.870 --> 00:52:56.410 align:middle line:84%
Most of the returns
will be private anyway,

00:52:56.410 --> 00:52:58.530 align:middle line:90%
so why not let you just go on?

00:52:58.530 --> 00:52:59.750 align:middle line:90%
And the answer would be two.

00:52:59.750 --> 00:53:02.610 align:middle line:84%
One is there are spillovers
even from education.

00:53:02.610 --> 00:53:05.090 align:middle line:84%
So there is evidence that even
educating people in college

00:53:05.090 --> 00:53:06.870 align:middle line:90%
has positive externalities.

00:53:06.870 --> 00:53:08.730 align:middle line:84%
So that's one argument
for why we'd still

00:53:08.730 --> 00:53:10.390 align:middle line:84%
want the government involved
in higher education.

00:53:10.390 --> 00:53:11.973 align:middle line:84%
There are still
positive externalities

00:53:11.973 --> 00:53:13.290 align:middle line:90%
for higher education.

00:53:13.290 --> 00:53:15.447 align:middle line:90%
Two is credit market failures.

00:53:15.447 --> 00:53:18.030 align:middle line:84%
Like I said last time, you can't
offer yourself as collateral.

00:53:18.030 --> 00:53:19.925 align:middle line:90%
We call that slavery.

00:53:19.925 --> 00:53:21.550 align:middle line:84%
You can't offer
yourself as collateral.

00:53:21.550 --> 00:53:23.490 align:middle line:84%
As a result, you
can't necessarily

00:53:23.490 --> 00:53:26.930 align:middle line:84%
get loans to better education,
even if that would be

00:53:26.930 --> 00:53:29.250 align:middle line:90%
a good productive investment.

00:53:29.250 --> 00:53:31.410 align:middle line:84%
So credit market failures
is another reason

00:53:31.410 --> 00:53:34.490 align:middle line:84%
why we think the government
should be involved.

00:53:34.490 --> 00:53:36.990 align:middle line:84%
So how is the
government involved?

00:53:36.990 --> 00:53:42.590 align:middle line:84%
Well, the government involvement
is illustrated in figure 11-4.

00:53:42.590 --> 00:53:47.530 align:middle line:84%
The major way the government's
involved is public universities.

00:53:47.530 --> 00:53:49.470 align:middle line:84%
Like I said, 60% of
university students

00:53:49.470 --> 00:53:51.750 align:middle line:90%
do attend public universities.

00:53:51.750 --> 00:53:55.430 align:middle line:84%
And by far, the
largest expenditure

00:53:55.430 --> 00:54:00.270 align:middle line:84%
of the public sector
on higher education

00:54:00.270 --> 00:54:02.950 align:middle line:90%
is these public universities.

00:54:02.950 --> 00:54:08.630 align:middle line:84%
The second biggest is
what we call Pell grants.

00:54:08.630 --> 00:54:12.750 align:middle line:84%
Pell grants is a program that
provides grants to attend school

00:54:12.750 --> 00:54:14.478 align:middle line:90%
for lower-income families.

00:54:14.478 --> 00:54:16.270 align:middle line:84%
So it's a grant of
several thousand dollars

00:54:16.270 --> 00:54:18.670 align:middle line:84%
you can use to offset
the cost of college

00:54:18.670 --> 00:54:20.430 align:middle line:90%
for low-income families.

00:54:20.430 --> 00:54:23.270 align:middle line:84%
We spend $28 billion
a year on that.

00:54:23.270 --> 00:54:27.670 align:middle line:84%
The third and the
smallest is student loans.

00:54:27.670 --> 00:54:29.550 align:middle line:90%
Student loans are interesting.

00:54:29.550 --> 00:54:33.790 align:middle line:84%
We used to have a system where
we had two sources of loans.

00:54:33.790 --> 00:54:36.037 align:middle line:84%
Direct student
loans, which we're

00:54:36.037 --> 00:54:38.370 align:middle line:84%
borrowing from the government--
which is what all of you

00:54:38.370 --> 00:54:39.230 align:middle line:90%
do now if you have loans.

00:54:39.230 --> 00:54:40.610 align:middle line:90%
It's the only program available.

00:54:40.610 --> 00:54:42.985 align:middle line:84%
We also have something called
the Guaranteed Student Loan

00:54:42.985 --> 00:54:46.170 align:middle line:84%
program, the GSL program,
where basically the government

00:54:46.170 --> 00:54:48.338 align:middle line:84%
subsidized private
banks to loan you money.

00:54:48.338 --> 00:54:50.130 align:middle line:84%
Fascinating story, I'll
divert for a second

00:54:50.130 --> 00:54:51.990 align:middle line:84%
to talk about this,
because once again,

00:54:51.990 --> 00:54:54.130 align:middle line:84%
it comes to a
privatization issue.

00:54:54.130 --> 00:54:56.690 align:middle line:84%
The way this program
works is the government

00:54:56.690 --> 00:55:01.610 align:middle line:84%
said to banks, you loan money to
students at a certain interest

00:55:01.610 --> 00:55:02.250 align:middle line:90%
rate.

00:55:02.250 --> 00:55:06.250 align:middle line:84%
We will guarantee if
the students default. It

00:55:06.250 --> 00:55:09.450 align:middle line:84%
said to banks, essentially, we
are giving you a risk-free part

00:55:09.450 --> 00:55:11.410 align:middle line:90%
of your portfolio.

00:55:11.410 --> 00:55:17.010 align:middle line:84%
Now, the banks were like,
great, we'll make tons of money

00:55:17.010 --> 00:55:17.590 align:middle line:90%
on that.

00:55:17.590 --> 00:55:19.465 align:middle line:84%
Basically, why do banks
charge high interest?

00:55:19.465 --> 00:55:20.450 align:middle line:90%
Because of the risk.

00:55:20.450 --> 00:55:21.908 align:middle line:84%
Well, the government
was saying you

00:55:21.908 --> 00:55:25.530 align:middle line:84%
can charge your regular
interest rate with no risk.

00:55:25.530 --> 00:55:26.710 align:middle line:90%
The banks loved it.

00:55:26.710 --> 00:55:28.550 align:middle line:84%
Now, people realized
that was a problem.

00:55:28.550 --> 00:55:31.050 align:middle line:84%
And they passed a law which
said by a date certain,

00:55:31.050 --> 00:55:33.858 align:middle line:84%
the government had to reset the
interest rate for student loans.

00:55:33.858 --> 00:55:36.400 align:middle line:84%
That date certain was while I
was in the Treasury Department,

00:55:36.400 --> 00:55:38.180 align:middle line:84%
so I was the guy
in charge of this.

00:55:38.180 --> 00:55:40.638 align:middle line:84%
I was in charge of resetting
the interest on student loans.

00:55:40.638 --> 00:55:42.740 align:middle line:90%
This is 1998.

00:55:42.740 --> 00:55:46.540 align:middle line:84%
And we looked at
the data and decided

00:55:46.540 --> 00:55:49.260 align:middle line:84%
that banks were being
massively overpaid,

00:55:49.260 --> 00:55:51.020 align:middle line:90%
given the lack of risk.

00:55:51.020 --> 00:55:54.055 align:middle line:84%
And they should receive about
a percentage and a half less.

00:55:54.055 --> 00:55:55.180 align:middle line:90%
I forget the exact numbers.

00:55:55.180 --> 00:55:57.740 align:middle line:84%
It's about 1 and 1/2% less
in interest for these student

00:55:57.740 --> 00:55:58.240 align:middle line:90%
loans.

00:55:58.240 --> 00:55:59.900 align:middle line:90%
We should cut it.

00:55:59.900 --> 00:56:00.680 align:middle line:90%
We announced this.

00:56:00.680 --> 00:56:01.960 align:middle line:84%
I was there the day
they announced it.

00:56:01.960 --> 00:56:03.790 align:middle line:84%
Al Gore and I even
had the same tie on.

00:56:03.790 --> 00:56:05.040 align:middle line:90%
I was very excited about that.

00:56:05.040 --> 00:56:06.080 align:middle line:90%
There they announced it.

00:56:06.080 --> 00:56:08.262 align:middle line:84%
We're going to cut student
loan interest rates.

00:56:08.262 --> 00:56:09.720 align:middle line:84%
All the students
were very excited.

00:56:09.720 --> 00:56:11.252 align:middle line:90%
The banks were super-pissed.

00:56:11.252 --> 00:56:11.960 align:middle line:90%
Oh it's terrible.

00:56:11.960 --> 00:56:12.752 align:middle line:90%
We can't afford it.

00:56:12.752 --> 00:56:13.820 align:middle line:90%
We'll go out of business.

00:56:13.820 --> 00:56:16.860 align:middle line:84%
Well, it turns out the banks
have very good lobbyists.

00:56:16.860 --> 00:56:19.820 align:middle line:84%
And the lobbyists started really
putting pressure on Congress

00:56:19.820 --> 00:56:21.460 align:middle line:90%
to not approve this.

00:56:21.460 --> 00:56:25.590 align:middle line:84%
Well, meanwhile, the Clinton
administration, the student

00:56:25.590 --> 00:56:26.840 align:middle line:90%
groups were like, we love you.

00:56:26.840 --> 00:56:27.870 align:middle line:90%
You can't back off this.

00:56:27.870 --> 00:56:29.620 align:middle line:84%
So Congress and the
Clinton administration

00:56:29.620 --> 00:56:31.640 align:middle line:90%
were caught in a tough position.

00:56:31.640 --> 00:56:32.640 align:middle line:90%
They put this out there.

00:56:32.640 --> 00:56:34.980 align:middle line:84%
Student groups were excited
about paying lower interest.

00:56:34.980 --> 00:56:36.680 align:middle line:90%
But the banks were mad.

00:56:36.680 --> 00:56:39.760 align:middle line:84%
So here's the interesting,
depressing chapter 9 lesson.

00:56:39.760 --> 00:56:42.840 align:middle line:84%
Between an immovable force--
between an unstoppable force

00:56:42.840 --> 00:56:44.480 align:middle line:84%
and immovable object,
there's actually

00:56:44.480 --> 00:56:45.660 align:middle line:90%
something in between them.

00:56:45.660 --> 00:56:46.860 align:middle line:90%
It's called the deficit.

00:56:46.860 --> 00:56:48.000 align:middle line:90%
[LAUGHTER]

00:56:48.000 --> 00:56:49.380 align:middle line:90%
So what did the government do?

00:56:49.380 --> 00:56:50.880 align:middle line:84%
They said, OK, we'll
continue to pay

00:56:50.880 --> 00:56:52.380 align:middle line:90%
the banks who are paying them.

00:56:52.380 --> 00:56:53.340 align:middle line:90%
Students will pay less.

00:56:53.340 --> 00:56:55.160 align:middle line:84%
And the government will
pay the difference.

00:56:55.160 --> 00:56:57.120 align:middle line:84%
So let's be clear about
what they decided.

00:56:57.120 --> 00:56:59.920 align:middle line:84%
They decided the government
would send checks to the banks

00:56:59.920 --> 00:57:02.640 align:middle line:84%
to make profitable
loans to students.

00:57:02.640 --> 00:57:06.240 align:middle line:84%
That is one of the
saddest episodes

00:57:06.240 --> 00:57:08.760 align:middle line:90%
of my time in Washington.

00:57:08.760 --> 00:57:11.380 align:middle line:84%
Fortunately, under the
Obama administration,

00:57:11.380 --> 00:57:13.940 align:middle line:84%
they actually got rid of the
Guaranteed Student Loan program.

00:57:13.940 --> 00:57:15.523 align:middle line:84%
And now the government
makes the loans

00:57:15.523 --> 00:57:18.400 align:middle line:84%
directly under the Direct Loan
program from the government.

00:57:18.400 --> 00:57:22.360 align:middle line:90%
And these don't cost a ton.

00:57:22.360 --> 00:57:25.200 align:middle line:90%
These don't cost a ton.

00:57:25.200 --> 00:57:27.580 align:middle line:84%
We'll come back later to
the major issues with them.

00:57:27.580 --> 00:57:32.990 align:middle line:84%
Now let's look at this chart
and ask, how is the government

00:57:32.990 --> 00:57:35.240 align:middle line:84%
spending related to the
market failures we identified?

00:57:35.240 --> 00:57:37.020 align:middle line:84%
We identified two
market failures.

00:57:37.020 --> 00:57:40.320 align:middle line:84%
One is that there may
be positive spillovers.

00:57:40.320 --> 00:57:42.420 align:middle line:84%
Well, that would be about
the size of the pie.

00:57:42.420 --> 00:57:43.720 align:middle line:84%
It's not really about
how we divide it up.

00:57:43.720 --> 00:57:44.960 align:middle line:84%
That would be like the
bigger the spillovers,

00:57:44.960 --> 00:57:47.740 align:middle line:84%
the bigger the pie should
be of government spending.

00:57:47.740 --> 00:57:50.257 align:middle line:84%
The second is credit
market failures.

00:57:50.257 --> 00:57:52.340 align:middle line:84%
Well, that would suggest
that the big slice should

00:57:52.340 --> 00:57:55.780 align:middle line:90%
be loans, not state spending.

00:57:55.780 --> 00:57:58.580 align:middle line:84%
So in fact, just like
we talked about Tiebout

00:57:58.580 --> 00:58:01.180 align:middle line:84%
and talked about how the way
federal and local spending

00:58:01.180 --> 00:58:04.940 align:middle line:84%
lines up with the model, this
doesn't line up with the model.

00:58:04.940 --> 00:58:07.580 align:middle line:84%
The model would say we should
be making big loans, not just

00:58:07.580 --> 00:58:10.940 align:middle line:84%
spending tons of money to
provide this education for free.

00:58:10.940 --> 00:58:14.300 align:middle line:90%
So what is the justification?

00:58:14.300 --> 00:58:17.520 align:middle line:90%
Well, it's hard, to be honest.

00:58:17.520 --> 00:58:21.420 align:middle line:84%
I mean, to some extent,
some of the justification

00:58:21.420 --> 00:58:24.260 align:middle line:84%
is that students who
get loans may not

00:58:24.260 --> 00:58:26.200 align:middle line:84%
choose the socially
optimal career paths.

00:58:26.200 --> 00:58:28.810 align:middle line:90%
So some really cool studies--

00:58:28.810 --> 00:58:30.560 align:middle line:84%
because you also forget
the state schools.

00:58:30.560 --> 00:58:31.518 align:middle line:90%
Let's leave that alone.

00:58:31.518 --> 00:58:33.680 align:middle line:84%
Just look at the grants
versus loan size.

00:58:33.680 --> 00:58:36.740 align:middle line:84%
We spend almost 10 times as
much on grants and loans.

00:58:36.740 --> 00:58:39.073 align:middle line:84%
Whereas the credit market
failure, you want the reverse.

00:58:39.073 --> 00:58:40.657 align:middle line:84%
But there's actually
some cool studies

00:58:40.657 --> 00:58:43.320 align:middle line:84%
which have compared people who
randomly had grants versus loans

00:58:43.320 --> 00:58:44.960 align:middle line:84%
based on school
policies and stuff.

00:58:44.960 --> 00:58:47.280 align:middle line:84%
And they find that
when you get a loan,

00:58:47.280 --> 00:58:52.240 align:middle line:84%
you're much more likely to
pursue a higher-earning career,

00:58:52.240 --> 00:58:55.520 align:middle line:84%
as opposed to what we
might call a lower reward

00:58:55.520 --> 00:58:58.480 align:middle line:84%
or more socially valuable
relative to dollars career.

00:58:58.480 --> 00:59:02.020 align:middle line:84%
So for instance,
at NYU Law School,

00:59:02.020 --> 00:59:05.435 align:middle line:84%
they changed from grants
to loans, or vice versa.

00:59:05.435 --> 00:59:07.560 align:middle line:84%
And students stopped going
into public interest law

00:59:07.560 --> 00:59:10.000 align:middle line:84%
and start going
to corporate law.

00:59:10.000 --> 00:59:12.500 align:middle line:84%
Now, I don't want to diss
the corporate lawyers.

00:59:12.500 --> 00:59:13.760 align:middle line:90%
There's social value there.

00:59:13.760 --> 00:59:17.720 align:middle line:84%
I'm just saying that those
things do affect choice.

00:59:17.720 --> 00:59:19.720 align:middle line:90%
So that's one argument.

00:59:19.720 --> 00:59:21.960 align:middle line:84%
That still isn't really
a terrific argument

00:59:21.960 --> 00:59:25.100 align:middle line:84%
for why we spend so much on
state and local colleges.

00:59:25.100 --> 00:59:27.800 align:middle line:84%
And that is, I think, an open
and interesting question.

00:59:27.800 --> 00:59:30.152 align:middle line:84%
The return to college
is still high.

00:59:30.152 --> 00:59:31.860 align:middle line:84%
So there's been nice
randomized studies--

00:59:31.860 --> 00:59:34.670 align:middle line:84%
there's a really cool randomized
study recently super cool study.

00:59:34.670 --> 00:59:35.420 align:middle line:90%
What the guy did--

00:59:35.420 --> 00:59:36.380 align:middle line:90%
I saw it this summer.

00:59:36.380 --> 00:59:39.860 align:middle line:90%


00:59:39.860 --> 00:59:42.260 align:middle line:84%
Basically what he
did is said, there's

00:59:42.260 --> 00:59:44.420 align:middle line:90%
all these colleges in Texas.

00:59:44.420 --> 00:59:46.708 align:middle line:84%
And essentially, he
could look at the data.

00:59:46.708 --> 00:59:48.500 align:middle line:84%
And they each have
somewhat different rules

00:59:48.500 --> 00:59:50.960 align:middle line:84%
about the score you need to
get accepted-- your GPA cutoff.

00:59:50.960 --> 00:59:53.740 align:middle line:84%
And you can actually see
the GPA cutoff in the data.

00:59:53.740 --> 00:59:56.860 align:middle line:84%
So he did what's called--
we'll cover this later.

00:59:56.860 --> 00:59:59.995 align:middle line:84%
Valerie, did you do regression
discontinuity in chapter 3?

00:59:59.995 --> 01:00:00.620 align:middle line:90%
AUDIENCE: Yeah.

01:00:00.620 --> 01:00:01.340 align:middle line:90%
JON GRUBER: OK.

01:00:01.340 --> 01:00:03.460 align:middle line:84%
Basically, this is a
technique we'll spend

01:00:03.460 --> 01:00:04.840 align:middle line:90%
more time in the semester.

01:00:04.840 --> 01:00:07.580 align:middle line:84%
But essentially, the
idea is the following.

01:00:07.580 --> 01:00:11.500 align:middle line:84%
Let's say you have some score
distribution You have some score

01:00:11.500 --> 01:00:17.060 align:middle line:84%
distribution, and there's some
random cutoff put in here.

01:00:17.060 --> 01:00:21.180 align:middle line:84%
Well, these people are really
different than these people.

01:00:21.180 --> 01:00:23.880 align:middle line:84%
But these people aren't so
different from those people.

01:00:23.880 --> 01:00:27.500 align:middle line:84%
So if you know if
there's a random cutoff,

01:00:27.500 --> 01:00:29.300 align:middle line:90%
it's called a discontinuity.

01:00:29.300 --> 01:00:31.720 align:middle line:84%
You can compare people
right around that cutoff who

01:00:31.720 --> 01:00:33.500 align:middle line:90%
are pretty likely identical.

01:00:33.500 --> 01:00:35.520 align:middle line:90%
But one got in and one didn't.

01:00:35.520 --> 01:00:37.823 align:middle line:90%
So it's like the lottery.

01:00:37.823 --> 01:00:39.740 align:middle line:84%
But it doesn't come from
a randomized lottery.

01:00:39.740 --> 01:00:41.320 align:middle line:84%
It comes from a cutoff
and comparing people

01:00:41.320 --> 01:00:41.880 align:middle line:90%
right around that.

01:00:41.880 --> 01:00:43.422 align:middle line:84%
Now, it's not as
good as the lottery.

01:00:43.422 --> 01:00:45.088 align:middle line:84%
You can say, well,
people are different.

01:00:45.088 --> 01:00:46.040 align:middle line:90%
They're not identical.

01:00:46.040 --> 01:00:48.207 align:middle line:84%
We have methods to try to
see how identical they are

01:00:48.207 --> 01:00:50.320 align:middle line:84%
and there's lots of
statistical tests you can do.

01:00:50.320 --> 01:00:52.237 align:middle line:84%
But in principle, if you
get arbitrarily close

01:00:52.237 --> 01:00:54.648 align:middle line:90%
to this cutoff, it is random.

01:00:54.648 --> 01:00:56.440 align:middle line:84%
Literally, if you have
a million people who

01:00:56.440 --> 01:01:00.200 align:middle line:84%
score 3.49 and a million
people who score 3.51,

01:01:00.200 --> 01:01:03.560 align:middle line:84%
and the cutoff is 3.5, those
are pretty much the same people

01:01:03.560 --> 01:01:05.240 align:middle line:90%
and you can compare them.

01:01:05.240 --> 01:01:07.120 align:middle line:84%
And what this guy
did is, he found

01:01:07.120 --> 01:01:09.968 align:middle line:84%
that this line moved for
different schools around Texas.

01:01:09.968 --> 01:01:11.760 align:middle line:84%
There's all these little
tests he could do.

01:01:11.760 --> 01:01:13.540 align:middle line:84%
At every school, he
do a little test.

01:01:13.540 --> 01:01:14.560 align:middle line:84%
And what he found
doing that was,

01:01:14.560 --> 01:01:16.060 align:middle line:84%
there was a very
high rate of return

01:01:16.060 --> 01:01:17.460 align:middle line:90%
to public education in Texas.

01:01:17.460 --> 01:01:21.600 align:middle line:90%


01:01:21.600 --> 01:01:23.240 align:middle line:84%
That just says the
size of the circle

01:01:23.240 --> 01:01:24.780 align:middle line:90%
may be, if anything, too small.

01:01:24.780 --> 01:01:27.280 align:middle line:84%
It still doesn't say why it
should be public schools and not

01:01:27.280 --> 01:01:28.860 align:middle line:90%
more loans to private schools.

01:01:28.860 --> 01:01:32.180 align:middle line:84%
Now, the answer to
that, to come to that,

01:01:32.180 --> 01:01:35.800 align:middle line:84%
we turn to the last big
topic I want to cover,

01:01:35.800 --> 01:01:37.088 align:middle line:90%
which is student loans.

01:01:37.088 --> 01:01:38.880 align:middle line:84%
And why don't we just
all do student loans?

01:01:38.880 --> 01:01:41.088 align:middle line:84%
And here, we have the big
issue of student loan debt.

01:01:41.088 --> 01:01:44.300 align:middle line:90%
As you know, we have about--

01:01:44.300 --> 01:01:47.040 align:middle line:84%
I think it's currently
several trillion dollars.

01:01:47.040 --> 01:01:50.100 align:middle line:84%
I don't remember what the stock
of student loan debt is now.

01:01:50.100 --> 01:01:52.080 align:middle line:84%
It's $1.4 trillion as
of a few years ago.

01:01:52.080 --> 01:01:53.760 align:middle line:90%
It's bigger than that now.

01:01:53.760 --> 01:01:57.220 align:middle line:84%
It's a huge stock of debt
that students are bearing.

01:01:57.220 --> 01:02:00.260 align:middle line:84%
And a lot of students
aren't paying it back.

01:02:00.260 --> 01:02:03.020 align:middle line:84%
24% of students are delinquent
at least one student loan

01:02:03.020 --> 01:02:04.340 align:middle line:90%
payment.

01:02:04.340 --> 01:02:07.780 align:middle line:84%
5% have defaulted altogether
on student loan payments.

01:02:07.780 --> 01:02:12.180 align:middle line:84%
And 22% of workers have
student loan payments

01:02:12.180 --> 01:02:14.360 align:middle line:84%
that amount to more than
12% of their income.

01:02:14.360 --> 01:02:15.740 align:middle line:84%
That is, more than one
in eight of every dollar

01:02:15.740 --> 01:02:17.448 align:middle line:84%
is going to pay back
their student loans.

01:02:17.448 --> 01:02:19.180 align:middle line:90%
That's a huge loan burden.

01:02:19.180 --> 01:02:22.043 align:middle line:84%
So one argument for why we
should rely less on loans

01:02:22.043 --> 01:02:24.460 align:middle line:84%
and more on spending-- although
again, it doesn't tell you

01:02:24.460 --> 01:02:25.860 align:middle line:90%
the purple versus the green.

01:02:25.860 --> 01:02:28.373 align:middle line:84%
It's just the purple and
the green versus the orange.

01:02:28.373 --> 01:02:30.040 align:middle line:84%
Essentially, these
student loans, people

01:02:30.040 --> 01:02:32.080 align:middle line:90%
can't afford to pay them back.

01:02:32.080 --> 01:02:37.000 align:middle line:84%
And that has led to a big
debate over allowing people

01:02:37.000 --> 01:02:39.458 align:middle line:84%
to default on their student
loans, forgiving student loans.

01:02:39.458 --> 01:02:41.375 align:middle line:84%
This is something that
Elizabeth Warren really

01:02:41.375 --> 01:02:43.140 align:middle line:84%
raised people's
attention as a candidate.

01:02:43.140 --> 01:02:45.723 align:middle line:84%
And the Biden administration has
made a focus of their efforts

01:02:45.723 --> 01:02:47.505 align:middle line:90%
to forgive student loans.

01:02:47.505 --> 01:02:49.630 align:middle line:84%
They had a big plan to
forgive student loans, which

01:02:49.630 --> 01:02:51.547 align:middle line:84%
would have forgiven like
a huge share of them.

01:02:51.547 --> 01:02:53.320 align:middle line:84%
The Supreme Court
turned it down,

01:02:53.320 --> 01:02:54.900 align:middle line:84%
and then they put
in a smaller plan.

01:02:54.900 --> 01:02:56.200 align:middle line:84%
But still, they released
student loans of something

01:02:56.200 --> 01:02:57.680 align:middle line:90%
like four million people.

01:02:57.680 --> 01:03:02.560 align:middle line:84%
Four million people got
their student loans paid for.

01:03:02.560 --> 01:03:04.800 align:middle line:84%
They didn't have to pay
back their student loans.

01:03:04.800 --> 01:03:07.420 align:middle line:84%
So the question is, what
is the right strategy here?

01:03:07.420 --> 01:03:10.563 align:middle line:84%
There's a lot of arguments
against just allowing people

01:03:10.563 --> 01:03:11.980 align:middle line:84%
to default on their
student loans.

01:03:11.980 --> 01:03:14.000 align:middle line:84%
And one is the moral
hazard argument.

01:03:14.000 --> 01:03:15.260 align:middle line:84%
If you're going to let
some people to follow,

01:03:15.260 --> 01:03:16.843 align:middle line:84%
other people won't
pay because they'll

01:03:16.843 --> 01:03:18.560 align:middle line:90%
think they'll get to default.

01:03:18.560 --> 01:03:20.755 align:middle line:84%
There's also an equity
argument, which is,

01:03:20.755 --> 01:03:22.880 align:middle line:84%
what about people who paid
back their student loans

01:03:22.880 --> 01:03:24.630 align:middle line:84%
and struggled and worked
really hard to pay them back?

01:03:24.630 --> 01:03:27.090 align:middle line:84%
And someone else just had
the government pay them back.

01:03:27.090 --> 01:03:29.650 align:middle line:84%
That seems a little
bit inequitable.

01:03:29.650 --> 01:03:31.930 align:middle line:84%
So there's some
arguments against that.

01:03:31.930 --> 01:03:34.770 align:middle line:84%
The argument for it is,
a lot of these loans

01:03:34.770 --> 01:03:37.350 align:middle line:84%
are based on students
who are essentially

01:03:37.350 --> 01:03:38.630 align:middle line:90%
fraudulently educated.

01:03:38.630 --> 01:03:40.890 align:middle line:84%
I'm not just talking about
Trump University here.

01:03:40.890 --> 01:03:44.650 align:middle line:84%
But I'm talking about a broad
sector of for-profit colleges

01:03:44.650 --> 01:03:49.850 align:middle line:84%
that have actually shown to be
very bad actors in many cases.

01:03:49.850 --> 01:03:52.270 align:middle line:84%
For example, the ITT
Technical Institute--

01:03:52.270 --> 01:03:54.570 align:middle line:84%
do you guys ever see ITT
Technical Institute ads on TV?

01:03:54.570 --> 01:03:58.010 align:middle line:84%
They ran an aggressive
campaign ad in radio.

01:03:58.010 --> 01:04:00.230 align:middle line:84%
They found these
commercials were dishonest.

01:04:00.230 --> 01:04:02.530 align:middle line:84%
The government study--
were dishonest and targeted

01:04:02.530 --> 01:04:04.170 align:middle line:90%
low-income students.

01:04:04.170 --> 01:04:06.685 align:middle line:84%
Basically, ITT would
reach out to you and say,

01:04:06.685 --> 01:04:07.810 align:middle line:90%
we're going to educate you.

01:04:07.810 --> 01:04:09.268 align:middle line:84%
Here, it's going
to be free to you,

01:04:09.268 --> 01:04:12.230 align:middle line:84%
take out this big student
loan to pay for it.

01:04:12.230 --> 01:04:13.890 align:middle line:90%
And then they would give you--

01:04:13.890 --> 01:04:16.410 align:middle line:84%
and then they wouldn't give you
a really valuable education.

01:04:16.410 --> 01:04:20.050 align:middle line:84%
And basically, more
generally, if you

01:04:20.050 --> 01:04:22.710 align:middle line:84%
look at all students heading
to for-profit colleges,

01:04:22.710 --> 01:04:26.085 align:middle line:84%
one third graduate
within eight years.

01:04:26.085 --> 01:04:28.210 align:middle line:84%
So you define graduating
graduate with eight years.

01:04:28.210 --> 01:04:30.610 align:middle line:84%
2/3 don't even graduate within
eight years of attending.

01:04:30.610 --> 01:04:34.550 align:middle line:90%


01:04:34.550 --> 01:04:36.110 align:middle line:84%
A really cool study
looked at what

01:04:36.110 --> 01:04:38.190 align:middle line:84%
happened when for-profit
colleges closed

01:04:38.190 --> 01:04:40.350 align:middle line:84%
and the kids moved to
community colleges.

01:04:40.350 --> 01:04:44.310 align:middle line:84%
The graduation rates
went up from 34% to 60%.

01:04:44.310 --> 01:04:47.450 align:middle line:84%
So schools on average are
clearly doing a terrible job.

01:04:47.450 --> 01:04:49.920 align:middle line:84%
And there's fun
anecdotes like ITT.

01:04:49.920 --> 01:04:51.670 align:middle line:84%
But there's actually
the data, like I just

01:04:51.670 --> 01:04:53.962 align:middle line:84%
said to you, which is on
average for-profit schools are

01:04:53.962 --> 01:04:57.790 align:middle line:84%
doing a bad job, and in
particular, a misleading job.

01:04:57.790 --> 01:04:59.810 align:middle line:90%
Now, as always, it's not easy.

01:04:59.810 --> 01:05:01.310 align:middle line:84%
On the other hand,
there are studies

01:05:01.310 --> 01:05:04.190 align:middle line:84%
which show that many
disadvantaged students who

01:05:04.190 --> 01:05:07.510 align:middle line:84%
did not have the ability to
access traditional education

01:05:07.510 --> 01:05:09.500 align:middle line:84%
succeeded in
for-profit colleges.

01:05:09.500 --> 01:05:11.250 align:middle line:84%
So there are students
who succeeded there,

01:05:11.250 --> 01:05:12.630 align:middle line:84%
and it provided
a road to success

01:05:12.630 --> 01:05:15.590 align:middle line:84%
for some students who didn't
otherwise have access.

01:05:15.590 --> 01:05:19.550 align:middle line:84%
But on average, they don't seem
to be performing very well.

01:05:19.550 --> 01:05:24.470 align:middle line:84%
And so the argument was, these
people went to really scummy,

01:05:24.470 --> 01:05:26.450 align:middle line:84%
for-profit colleges who
misled them and made

01:05:26.450 --> 01:05:27.830 align:middle line:90%
them take big student loans.

01:05:27.830 --> 01:05:30.250 align:middle line:84%
They now have this
big student loan debt.

01:05:30.250 --> 01:05:32.810 align:middle line:84%
We shouldn't make
them pay it back.

01:05:32.810 --> 01:05:39.370 align:middle line:90%
Now, that is an argument.

01:05:39.370 --> 01:05:40.810 align:middle line:84%
But it turns out
nobody's talking

01:05:40.810 --> 01:05:42.650 align:middle line:84%
about forgiving loan debt
just for those students,

01:05:42.650 --> 01:05:43.990 align:middle line:84%
forgiving loan
debt for everyone.

01:05:43.990 --> 01:05:45.823 align:middle line:84%
So it's hard to explain,
that's the minority

01:05:45.823 --> 01:05:47.290 align:middle line:90%
of students with debt.

01:05:47.290 --> 01:05:49.770 align:middle line:84%
So the question is, are there
better things we can do?

01:05:49.770 --> 01:05:52.470 align:middle line:84%
And the Obama administration
tried to do some better things.

01:05:52.470 --> 01:05:56.550 align:middle line:84%
For example, they increased the
quality available to students,

01:05:56.550 --> 01:05:59.690 align:middle line:84%
so you understood what
you're getting into.

01:05:59.690 --> 01:06:01.890 align:middle line:84%
Also, a more
aggressive strategy was

01:06:01.890 --> 01:06:05.090 align:middle line:84%
to basically deny
eligibility for student loans

01:06:05.090 --> 01:06:08.027 align:middle line:84%
to schools that didn't show a
good enough graduation rate.

01:06:08.027 --> 01:06:10.610 align:middle line:84%
Basically, unless your schools
showed a good enough graduation

01:06:10.610 --> 01:06:12.310 align:middle line:84%
rate, you couldn't
get student loans.

01:06:12.310 --> 01:06:13.970 align:middle line:90%
This is an interesting example.

01:06:13.970 --> 01:06:16.570 align:middle line:84%
We talked here
about a disadvantage

01:06:16.570 --> 01:06:19.910 align:middle line:84%
of vouchers as excessive
specialization,

01:06:19.910 --> 01:06:22.035 align:middle line:90%
or bad performance in this case.

01:06:22.035 --> 01:06:23.910 align:middle line:84%
This is a way you could
try to regulate that.

01:06:23.910 --> 01:06:27.350 align:middle line:84%
You say, look, we are going
to regulate it to make sure

01:06:27.350 --> 01:06:30.150 align:middle line:84%
that you're a decent school by
only giving you only-- we're not

01:06:30.150 --> 01:06:31.552 align:middle line:90%
going to shut you down.

01:06:31.552 --> 01:06:33.010 align:middle line:84%
We're going to let
the market work.

01:06:33.010 --> 01:06:34.760 align:middle line:84%
But you can't get
student loans unless you

01:06:34.760 --> 01:06:37.710 align:middle line:90%
can show you're decent.

01:06:37.710 --> 01:06:40.350 align:middle line:84%
The Trump administration
killed that regulation.

01:06:40.350 --> 01:06:44.390 align:middle line:84%
And it never, as far as I
know, never went into effect.

01:06:44.390 --> 01:06:46.670 align:middle line:90%
So that's one approach.

01:06:46.670 --> 01:06:48.670 align:middle line:84%
Another approach
that I like a lot is

01:06:48.670 --> 01:06:52.790 align:middle line:84%
to do what the UK
and Australia do,

01:06:52.790 --> 01:06:54.310 align:middle line:84%
which is to replace
our current loan

01:06:54.310 --> 01:06:59.050 align:middle line:84%
program with what's called an
income-contingent loan program.

01:06:59.050 --> 01:07:02.030 align:middle line:84%
Basically, we'll loan you
money and you pay it back

01:07:02.030 --> 01:07:04.670 align:middle line:90%
as a fraction of your income.

01:07:04.670 --> 01:07:08.150 align:middle line:84%
So if you end up not making much
money, you don't owe much back.

01:07:08.150 --> 01:07:10.550 align:middle line:84%
You get rich, you
owe a lot back.

01:07:10.550 --> 01:07:13.390 align:middle line:84%
And just the way it works
in the UK is basically,

01:07:13.390 --> 01:07:17.290 align:middle line:84%
they exempt the first, like,
15,000 pounds of your earnings.

01:07:17.290 --> 01:07:21.850 align:middle line:84%
And every pound above 15,000,
you pay 9% back in student loan

01:07:21.850 --> 01:07:26.310 align:middle line:84%
payments until you've paid back
your loan or until 20 years,

01:07:26.310 --> 01:07:29.142 align:middle line:90%
at which point it just stops.

01:07:29.142 --> 01:07:31.350 align:middle line:84%
Basically, the government
is still losing some money.

01:07:31.350 --> 01:07:32.850 align:middle line:84%
They're not making them
pay back enough to make up

01:07:32.850 --> 01:07:35.130 align:middle line:84%
if people default. But
it's not nearly as much

01:07:35.130 --> 01:07:36.670 align:middle line:90%
as just paying for college.

01:07:36.670 --> 01:07:39.170 align:middle line:84%
And it's doing it in a more
equitable way because people pay

01:07:39.170 --> 01:07:41.850 align:middle line:90%
back a share of their earnings.

01:07:41.850 --> 01:07:46.650 align:middle line:84%
Now, the US has a
program like this.

01:07:46.650 --> 01:07:49.370 align:middle line:84%
And in fact, it's
fairly popular.

01:07:49.370 --> 01:07:52.450 align:middle line:84%
The problem is that basically,
people are still defaulting

01:07:52.450 --> 01:07:53.890 align:middle line:90%
on it, not paying back.

01:07:53.890 --> 01:07:56.130 align:middle line:84%
So one change the Biden
administration made

01:07:56.130 --> 01:07:57.850 align:middle line:84%
was to make the
income-contingent loan

01:07:57.850 --> 01:08:00.050 align:middle line:90%
program much more generous.

01:08:00.050 --> 01:08:02.950 align:middle line:84%
Basically, it used to be you had
to pay up to 10% of your income.

01:08:02.950 --> 01:08:04.810 align:middle line:84%
Now it's 5% of your income
or something like that.

01:08:04.810 --> 01:08:06.190 align:middle line:84%
I don't know exactly
what they did.

01:08:06.190 --> 01:08:07.982 align:middle line:84%
But they made the
income-contingent program

01:08:07.982 --> 01:08:12.530 align:middle line:84%
much more generous to try
to encourage use of it.

01:08:12.530 --> 01:08:15.210 align:middle line:84%
There's two problems
with this program.

01:08:15.210 --> 01:08:17.310 align:middle line:84%
Once again, you'll get
used to me saying that.

01:08:17.310 --> 01:08:20.710 align:middle line:84%
Harry Truman once said, I wish I
had a one-handed economist so he

01:08:20.710 --> 01:08:22.790 align:middle line:84%
couldn't say "on
the other hand."

01:08:22.790 --> 01:08:25.810 align:middle line:84%
The problem with
this is twofold.

01:08:25.810 --> 01:08:28.750 align:middle line:84%
First of all, as we'll
learn later in the semester,

01:08:28.750 --> 01:08:31.370 align:middle line:84%
taxes have distortionary
consequences.

01:08:31.370 --> 01:08:33.870 align:middle line:84%
And if you're going to have to
pay an extra 9% in everything

01:08:33.870 --> 01:08:36.830 align:middle line:84%
you earn, you might decide
not to work as hard.

01:08:36.830 --> 01:08:37.850 align:middle line:90%
I have a paper on that.

01:08:37.850 --> 01:08:38.683 align:middle line:90%
We looked in the UK.

01:08:38.683 --> 01:08:39.810 align:middle line:90%
There's no effect there.

01:08:39.810 --> 01:08:42.350 align:middle line:84%
It's meaningless in terms
of people don't really

01:08:42.350 --> 01:08:44.430 align:middle line:90%
respond to that.

01:08:44.430 --> 01:08:47.510 align:middle line:84%
The second concern
is, does this really

01:08:47.510 --> 01:08:49.590 align:middle line:90%
work when it's not mandatory?

01:08:49.590 --> 01:08:51.990 align:middle line:84%
After all, if you're
going to college

01:08:51.990 --> 01:08:53.689 align:middle line:84%
and you're anticipating
your earnings,

01:08:53.689 --> 01:08:55.981 align:middle line:84%
who's going to want to take
the income-contingent loan?

01:08:55.981 --> 01:08:58.024 align:middle line:90%


01:08:58.024 --> 01:08:59.649 align:middle line:84%
And who's going to
not want to take it?

01:08:59.649 --> 01:09:00.149 align:middle line:90%
Steven.

01:09:00.149 --> 01:09:01.053 align:middle line:90%
AUDIENCE: [INAUDIBLE]

01:09:01.053 --> 01:09:02.470 align:middle line:84%
JON GRUBER: Yeah,
people are going

01:09:02.470 --> 01:09:04.210 align:middle line:84%
to want to take it
those of lower income.

01:09:04.210 --> 01:09:05.710 align:middle line:84%
The ones who aren't
going to take it

01:09:05.710 --> 01:09:06.918 align:middle line:90%
are the ones who participate.

01:09:06.918 --> 01:09:08.830 align:middle line:90%
They're going to go to get rich.

01:09:08.830 --> 01:09:11.229 align:middle line:84%
This is a problem that
we'll discuss next lecture

01:09:11.229 --> 01:09:13.470 align:middle line:84%
called adverse selection,
a common problem

01:09:13.470 --> 01:09:15.210 align:middle line:90%
in insurance markets.

01:09:15.210 --> 01:09:17.649 align:middle line:84%
Basically, the problem is
that if only the people who

01:09:17.649 --> 01:09:19.566 align:middle line:84%
know they're going to
have low income take it,

01:09:19.566 --> 01:09:21.729 align:middle line:84%
you'll lose a lot of
money on the program.

01:09:21.729 --> 01:09:24.271 align:middle line:84%
So the other problem is it's
hard to have a program like this

01:09:24.271 --> 01:09:28.729 align:middle line:84%
be successful unless it's
mandatory, as it is in the UK

01:09:28.729 --> 01:09:30.290 align:middle line:90%
and in Australia.

01:09:30.290 --> 01:09:32.729 align:middle line:90%
You cannot take a loan.

01:09:32.729 --> 01:09:35.069 align:middle line:84%
We're not saying you
could not take a loan.

01:09:35.069 --> 01:09:37.915 align:middle line:84%
But if you want to take a loan,
it has to be income-contingent.

01:09:37.915 --> 01:09:40.290 align:middle line:84%
So it wouldn't fully solve
the adverse selection problem,

01:09:40.290 --> 01:09:41.529 align:middle line:84%
because people who
knew they were rich,

01:09:41.529 --> 01:09:43.810 align:middle line:84%
who were already rich,
could just not take loans.

01:09:43.810 --> 01:09:45.630 align:middle line:84%
But they probably, by and
large, already don't take loans.

01:09:45.630 --> 01:09:46.350 align:middle line:90%
So it's OK.

01:09:46.350 --> 01:09:46.850 align:middle line:90%
Yeah.

01:09:46.850 --> 01:09:49.441 align:middle line:84%
AUDIENCE: [INAUDIBLE] are people
allowed to [INAUDIBLE] take

01:09:49.441 --> 01:09:52.149 align:middle line:84%
private loans if they think they
will [? have ?] a higher income?

01:09:52.149 --> 01:09:54.250 align:middle line:84%
JON GRUBER: No, you cannot take
a loan to pay back your college,

01:09:54.250 --> 01:09:55.930 align:middle line:90%
unless it's from this program.

01:09:55.930 --> 01:09:57.972 align:middle line:84%
And also private loans,
they wouldn't loan to you

01:09:57.972 --> 01:09:59.748 align:middle line:90%
because there's no collateral.

01:09:59.748 --> 01:10:02.290 align:middle line:84%
I mean, the private market can't
exist, and probably wouldn't

01:10:02.290 --> 01:10:04.050 align:middle line:90%
exist, otherwise.

01:10:04.050 --> 01:10:06.190 align:middle line:90%
OK, other questions about that.

01:10:06.190 --> 01:10:07.890 align:middle line:90%
Yeah, Enoch.

01:10:07.890 --> 01:10:10.970 align:middle line:84%
AUDIENCE: You mentioned use
of colleges and basically

01:10:10.970 --> 01:10:12.710 align:middle line:90%
giving you useless education.

01:10:12.710 --> 01:10:17.150 align:middle line:84%
Is there anything about useless
degrees or degree paths that--

01:10:17.150 --> 01:10:19.050 align:middle line:84%
JON GRUBER: It's a
fantastic question.

01:10:19.050 --> 01:10:21.790 align:middle line:84%
So in some
Scandinavian countries,

01:10:21.790 --> 01:10:24.473 align:middle line:84%
where they had a certain number
of slots in higher education,

01:10:24.473 --> 01:10:26.390 align:middle line:84%
they would actually
change the number of slots

01:10:26.390 --> 01:10:27.765 align:middle line:84%
to reflect where
they felt people

01:10:27.765 --> 01:10:30.610 align:middle line:84%
should be educated-- more STEM
slots, fewer English slots.

01:10:30.610 --> 01:10:32.790 align:middle line:84%
I mean, I'm preaching
to the choir here.

01:10:32.790 --> 01:10:37.110 align:middle line:84%
But basically, that is a
really deep and hard question,

01:10:37.110 --> 01:10:40.430 align:middle line:84%
which is fundamentally, what
is the nature of the education

01:10:40.430 --> 01:10:41.790 align:middle line:90%
being delivered?

01:10:41.790 --> 01:10:44.265 align:middle line:84%
So the Obama
administration said,

01:10:44.265 --> 01:10:45.890 align:middle line:84%
we'll target loans
on graduation rates.

01:10:45.890 --> 01:10:47.030 align:middle line:90%
You could go further.

01:10:47.030 --> 01:10:48.990 align:middle line:84%
You could target loans
on who's ending up

01:10:48.990 --> 01:10:50.470 align:middle line:90%
in a successful career.

01:10:50.470 --> 01:10:52.972 align:middle line:84%
The problem is, you have
to define "success."

01:10:52.972 --> 01:10:54.430 align:middle line:84%
And in some sense,
the problem with

01:10:54.430 --> 01:10:56.055 align:middle line:84%
the income-contingent
system is that it

01:10:56.055 --> 01:10:57.710 align:middle line:90%
has the opposite incentive.

01:10:57.710 --> 01:10:59.950 align:middle line:84%
If you really think there's
a lot of education that's

01:10:59.950 --> 01:11:00.950 align:middle line:90%
useless--

01:11:00.950 --> 01:11:03.790 align:middle line:84%
education leads to useless jobs,
then you don't want to do that.

01:11:03.790 --> 01:11:06.630 align:middle line:84%
Once again, do you think wages
reflect social marginal value

01:11:06.630 --> 01:11:09.050 align:middle line:84%
product or private
marginal value product?

01:11:09.050 --> 01:11:12.200 align:middle line:84%
We think wages reflect social
value marginal product,

01:11:12.200 --> 01:11:14.400 align:middle line:84%
then we should basically
reward education leads

01:11:14.400 --> 01:11:16.040 align:middle line:90%
to the highest wages.

01:11:16.040 --> 01:11:19.060 align:middle line:84%
If we think wages reflect
private value marginal product,

01:11:19.060 --> 01:11:21.820 align:middle line:84%
but that there's externalities
that are aside from wages,

01:11:21.820 --> 01:11:23.460 align:middle line:84%
we shouldn't
necessarily target it.

01:11:23.460 --> 01:11:26.640 align:middle line:84%
So that's a really
interesting and hard question.

01:11:26.640 --> 01:11:28.960 align:middle line:90%
Other questions?

01:11:28.960 --> 01:11:32.840 align:middle line:84%
OK, there's a cool study
which tried to decide,

01:11:32.840 --> 01:11:35.280 align:middle line:90%
is going to MIT worth it?

01:11:35.280 --> 01:11:38.160 align:middle line:84%
Is going to better
schools worth it

01:11:38.160 --> 01:11:39.980 align:middle line:84%
compared to going
to worse schools?

01:11:39.980 --> 01:11:42.605 align:middle line:90%
How would you test that?

01:11:42.605 --> 01:11:44.480 align:middle line:84%
I mean, obviously, you're
different than kids

01:11:44.480 --> 01:11:45.647 align:middle line:90%
who go to different schools.

01:11:45.647 --> 01:11:46.977 align:middle line:90%
How would you test?

01:11:46.977 --> 01:11:48.060 align:middle line:90%
How would you set that up?

01:11:48.060 --> 01:11:50.890 align:middle line:84%
Let's say you wanted to
test, is going to school

01:11:50.890 --> 01:11:52.140 align:middle line:90%
A better than going to school?

01:11:52.140 --> 01:11:52.680 align:middle line:90%
B?

01:11:52.680 --> 01:11:53.220 align:middle line:90%
Yeah.

01:11:53.220 --> 01:11:55.582 align:middle line:84%
AUDIENCE: You take
a look at a sample

01:11:55.582 --> 01:11:57.540 align:middle line:84%
of people that have been
accepted to [? MIT. ?]

01:11:57.540 --> 01:11:58.582 align:middle line:90%
JON GRUBER: There you go.

01:11:58.582 --> 01:12:00.960 align:middle line:84%
There you have one of the
most famous education studies,

01:12:00.960 --> 01:12:02.960 align:middle line:90%
the Dale-Krueger study.

01:12:02.960 --> 01:12:04.785 align:middle line:90%
What they did is exactly that.

01:12:04.785 --> 01:12:07.160 align:middle line:84%
They found a bunch of people
accepted to multiple schools

01:12:07.160 --> 01:12:08.660 align:middle line:84%
and asked, if you
went to the better

01:12:08.660 --> 01:12:11.300 align:middle line:84%
school you were accepted to do,
did you end up doing better?

01:12:11.300 --> 01:12:14.860 align:middle line:84%
And the answer was
actually remarkably little.

01:12:14.860 --> 01:12:17.473 align:middle line:90%
A lot of it is screening.

01:12:17.473 --> 01:12:19.140 align:middle line:84%
The answer is, the
students who are good

01:12:19.140 --> 01:12:21.660 align:middle line:84%
did pretty well
wherever they went.

01:12:21.660 --> 01:12:24.380 align:middle line:84%
And indeed, there's a
really cool study done

01:12:24.380 --> 01:12:26.180 align:middle line:90%
by [? Rothschild ?] at Harvard.

01:12:26.180 --> 01:12:30.540 align:middle line:84%
They got data on parental income
and subsequent children income

01:12:30.540 --> 01:12:33.540 align:middle line:84%
and ranked schools by
their income mobility.

01:12:33.540 --> 01:12:35.580 align:middle line:84%
That is, how much did
schools improve your rank

01:12:35.580 --> 01:12:37.268 align:middle line:90%
in the income distribution?

01:12:37.268 --> 01:12:38.060 align:middle line:90%
And the answer is--

01:12:38.060 --> 01:12:39.310 align:middle line:90%
I don't remember what MIT did.

01:12:39.310 --> 01:12:40.727 align:middle line:84%
But the answer is
the best schools

01:12:40.727 --> 01:12:43.340 align:middle line:84%
are schools like CCNY in New
York-- the City College of New

01:12:43.340 --> 01:12:45.360 align:middle line:84%
York, which takes a lot
of disadvantaged kids,

01:12:45.360 --> 01:12:46.818 align:middle line:84%
gives them a really
good education,

01:12:46.818 --> 01:12:49.500 align:middle line:84%
and promotes them up
the income distribution.

01:12:49.500 --> 01:12:53.140 align:middle line:84%
Of the major universities,
Berkeley was the best.

01:12:53.140 --> 01:12:56.220 align:middle line:84%
And I don't remember
who did badly,

01:12:56.220 --> 01:12:58.032 align:middle line:84%
but I'm sure MIT
didn't do that well.

01:12:58.032 --> 01:12:59.240 align:middle line:90%
I don't know how well we did.

01:12:59.240 --> 01:13:01.120 align:middle line:84%
We probably did better
than a lot of the Ivies,

01:13:01.120 --> 01:13:02.537 align:middle line:84%
because once again,
we're training

01:13:02.537 --> 01:13:04.700 align:middle line:90%
in high-wage professions.

01:13:04.700 --> 01:13:08.360 align:middle line:84%
So anyway, bottom line-- higher
education, fascinating topic,

01:13:08.360 --> 01:13:10.840 align:middle line:84%
lots of work to be done, very
relevant to all of your lives

01:13:10.840 --> 01:13:11.500 align:middle line:90%
right now.

01:13:11.500 --> 01:13:14.660 align:middle line:84%
A-- The bottom line
is the government

01:13:14.660 --> 01:13:15.660 align:middle line:90%
should clearly be in it.

01:13:15.660 --> 01:13:17.220 align:middle line:90%
There's positive externalities.

01:13:17.220 --> 01:13:19.240 align:middle line:90%
How much is still unclear.

01:13:19.240 --> 01:13:23.200 align:middle line:84%
B-- it's really unclear why we
spend our money the way we do,

01:13:23.200 --> 01:13:24.502 align:middle line:90%
as opposed to more loans.

01:13:24.502 --> 01:13:25.960 align:middle line:84%
But C, if we rely
more on loans, we

01:13:25.960 --> 01:13:27.335 align:middle line:84%
need to think
about the structure

01:13:27.335 --> 01:13:30.020 align:middle line:84%
of who gets those loans
and how they're paid back.

01:13:30.020 --> 01:13:31.960 align:middle line:90%
Any other questions on that?

01:13:31.960 --> 01:13:32.880 align:middle line:90%
Yeah, Enoch,

01:13:32.880 --> 01:13:33.880 align:middle line:90%
AUDIENCE: Why don't we--

01:13:33.880 --> 01:13:37.080 align:middle line:84%
I know a couple years back,
they did free college.

01:13:37.080 --> 01:13:39.280 align:middle line:84%
JON GRUBER: Free
college is another idea.

01:13:39.280 --> 01:13:41.040 align:middle line:84%
Once again, first of
all, the main reason,

01:13:41.040 --> 01:13:43.720 align:middle line:84%
it would be
unbelievably expensive.

01:13:43.720 --> 01:13:46.260 align:middle line:84%
And second of all comes
to your earlier question,

01:13:46.260 --> 01:13:49.440 align:middle line:84%
which is not obvious college is
the right thing for everyone.

01:13:49.440 --> 01:13:50.960 align:middle line:84%
There's a big debate
right now about

01:13:50.960 --> 01:13:52.860 align:middle line:84%
whether people are wasting
their money in college,

01:13:52.860 --> 01:13:55.382 align:middle line:84%
getting needlessly in debt to
something that isn't actually

01:13:55.382 --> 01:13:57.840 align:middle line:84%
making them do any better than
not going to college at all.

01:13:57.840 --> 01:14:01.440 align:middle line:84%
So I think that's an
interesting debate to be had.

01:14:01.440 --> 01:14:03.950 align:middle line:90%
All right, let's stop there.

01:14:03.950 --> 01:14:08.000 align:middle line:90%
