Announcements
Answers to final exam are now posted. Top score = 94, median = 81.
Pick up your corrected exam at your convenience when Dan is in the office: at latest 1:303:30pm Wednesday April 11, but preferably before that!
Advanced Microeconomic Theory II The second quarter of the Ph.D. microeconomics sequence, this course covers the fundamentals of information and decision theory, game theory and imperfect competition. There will be biweekly problem sets, a midterm and a 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 11:40am – 1:15PM in 319 Kresge.
Section meets Wednesdays 3:304:30 in 499 Engineering 2.
Office hours are W 1:302:30pm in 417 Engineering 2, and by appointment.

Continuous Dilemma // Posted on Feb. 15, 2018
A repeated game in continuous time. Optional material, will not be on exams.
Some of the article is technical, but it makes two points that might be worth a thought. Cooperation rates are quite high in a finite horizon prisoner's dilemma game played out in essentially continuous time. And these can be explained by an extension of Radner's 1986 analysis, which introduces epsilon equilibria.

Proof that Nash Equilibrium exists in finite NFGs. // Posted on Feb. 1, 2018
Streamlined, selfcontained proof by Adam Brandenberger. Note that it works for all sorts of games that are not finite. Here is a challenge: find a game that has no NE even in mixed strategies. Easier: what can we say about the payoff function of such a game?
