Econ 204B  Advanced Microeconomics II // Prof. Dan Friedman
Announcements
Solutions to the final exam are now posted...
Advanced Microeconomic Theory II, the second quarter of the Ph.D. microeconomics sequence, covers the fundamentals of information and decision theory, game theory and imperfect competition. There will be biweekly problem sets, an inclass midterm and an inclass final.
Students should own (or have regular access to) the principal text, Microeconomic Theory by MasColell, Whinston and Green (Oxford, 1995, ISBN=0195073401, denoted MWG below). They also should have at least occasional access to two secondary texts: The Analytics of Uncertainty and Information, by Hirshleifer and Riley (Cambridge University Press, 1992, denoted HR below) for information and decision theory, and Strategy: An Introduction to Game Theory, Second Edition by J. Watson (WW Norton, 2008, ISBN13=9780393929348 denoted W08 below) for game theory. It will be useful on occasion to consult the alternative texts: A Course in Microeconomic Theory by David M. Kreps (Princeton University Press, 1990) and Microeconomic Analysis, 3rd Edition, by Hal R. Varian (Norton, 1992). All these books will be on reserve in the Science Library.
Lecture notes and supplemental readings will be posted below. Each student is expected to help prepare the answer key to one problem set, which then will also be posted below.
The class meets Tu Th 8:00 – 9:35am in 169 JBE.
Section meets Wed 3:30  4:30pm in 499 Engineering 2.
Office hours are W 1:303:30pm in 417 Engineering 2, and by appointment.

Ten Treasures plus ten empirical NE counterexamples // Posted on Jan. 30, 2020

Continuous Dilemma paper // Posted on Feb. 11, 2014
Students interested in repeated game theory and applications may find the introduction and concluding discussion of this paper worth reading. The math appendix is not for everyone, but does touch on epsilon equilibria and begins to formalize some new intuition.
The paper won the Exeter Prize for the best paper published anywhere in 2012 on decision theory, behavioral or experimental economics.
