This course is designed as an introduction to theories and applications of games with asymmetric information. We start with an introduction to the modeling of such games and then introduce the fundamental problem of adverse selection. We then analyze the most popular communication games including signaling games, disclosure games, and cheap talk games. We then consider the mechanism design approach. We finish with applications to auctions and to various aspects of reputation.
