In this course, we examine important topics in microeconomics. The topics for this year are games of asymmetric information and their applications in auctions, mechanism design, and contracts. We first discuss game theory concepts, such as Nash equilibrium, subgame-perfect equilibrium, Bayesian equilibrium, perfect Bayesian equilibrium, and then apply them to auctions, optimal auctions, signaling, adverse selection, moral hazard, and incentive contracts. Course materials consist of lecture notes and papers from the literature.
