Macroeconomic Theory II

Readings

There are no textbooks for the course. Material will come from several sources. Readings by session are given below.

Covers most bases, but is aging:

Buy at MIT Press [BF] Blanchard, O., and S. Fischer. Lectures on Macroeconomics. Cambridge, MA: MIT Press, 1989. ISBN: 9780262022835.

Focuses more on open economy issues:

Buy at MIT Press [OR] Obstfeld, M., and K. Rogoff. Foundations of International Macroeconomics. Cambridge, MA: MIT Press, 1996. ISBN: 9780262150477.

Focuses more on nominal rigidities, and the role of monetary policy:

[MW] Woodford, M. Interest and Prices: Foundations of a Theory of Monetary Policy. Princeton, NJ: Princeton University Press, 2003. ISBN: 9780691010496.

Macroeconomics is a rapidly changing field. To get a sense of the geography, you might find it useful to read two surveys (which are already on the verge of obsolescence…):

Blanchard, O. “What Do We Know About Macroeconomics that Fisher and Wicksell Did Not?” Quarterly Journal of Economics 115, no. 4 (November 2000): 1375-1410.

Woodford, M. “Revolution and Evolution in Twentieth-Century Macroeconomics.” Paper presented at Frontiers of the Mind in the Twenty-First Century, U.S. Library of Congress, Washington, DC, June 1999.

For two more recent and more polemical, pieces, you may also want to read:

Chari, V. V. “Modern Macroeconomics in Practice: How Theory is Shaping Policy.” Journal of Economic Perspectives 20, no. 4 (2006): 3-28.

Mankiw, N. G. “The Macroeconomist as Scientist and Engineer.” Journal of Economic Perspectives 20, no. 4 (2006): 29-46.
