Lecture Notes

Syllabus

Course Overview

This course is part of the economics department field sequence in microeconomic theory. The course is designed to provide a rigorous treatment of the tools of contract theory, focusing in particular on models with hidden actions and
hidden information. Topics include moral hazard, adverse selection, mechanism design (with a special focus on auction theory), incomplete contracts, and financial contracting.

The course is highly required for students who intend to do theoretical research in microeconomic theory or any of the applied microeconomic fields. The tools developed in the course have become standard for economic modeling in many areas.

Prerequisites and Enrollment

This class is intended primarily for PhD students in the economics department and Sloan school PhD students intending to do formal economic theory in their dissertations. Due to its rigor and intensity, it will probably not serve the needs of master's students or undergraduates very well.

The prerequisite for the course is 14.121, but students with only that background may find the course too difficult. 14.122 and especially 14.124 (which treats many of these topics at an introductory level) are highly recommended.

Course Requirements

There will be approximately six to eight problem sets, which will be graded and will count 20% of the grade. There will also be a final exam. Details will be arranged in class.
