This half-semester course provides an introduction to microeconomic theory designed to meet the needs of students in the economics Ph.D. program. Some parts of the course are designed to teach material that all graduate students should know. Others are used to introduce methodologies. Topics include consumer and producer theory, markets and competition, general equilibrium, and tools of comparative statics and their application to price theory. Some topics of recent interest may also be covered.
Prerequisites for this course include 14.04 Intermediate Microeconomic Theory, 18.02 Multivariable Calculus, and 18.06 Linear Algebra.
Enrollment in this course is limited and permission of the instructor is required. Permission can be obtained by attending the first class meeting and providing information about previous coursework in mathematics and economics. The course assumes that students have taken undergraduate intermediate microeconomics classes. It also assumes that students are comfortable with multivariable calculus and linear algebra and have had some exposure to real analysis. Historically, many students from outside the economics department have had difficulty with the course. The enrollment limit may result in well-qualified students being turned away.

Some students have also found the following books helpful:

The course will be graded on the basis of six problem sets and a final exam.
Problem sets will be due in class on assigned lecture dates. They will be graded on a check-, check, check+ basis. The grades are intended primarily to give you an idea of how you are doing in the course and will affect course grades only for students with borderline scores on the exam. You may work in groups, but please do the write-ups individually. We do not expect to see identical answers from different students. An optional seventh problem set will be distributed.
The final exam will be held two days after the last lecture.
