### Updated A.Y. 2020-2021

Static games of complete Information: main solution concepts. Existence theorems. Applications: models of imperfect competition. Dynamic games of complete information. Representation through extensive form and backward induction. Subgame perfection. Introduction to repeated games. Applications: bargaining models. Games of incomplete information and bayesian equilibria. Adverse selection. Applications: Competitive screening and signalling in the labor market. Moral hazard. Application: Strategic default in financial markets.

### Updated A.Y. 2019-2020

The first objective of this course is to make students familiar with strategic thinking. The

second one is to introduce them to the theoretical analysis of incentive problems, and on their

implications for our understanding of competitive markets. The course is based on standard

textbooks, but I will also refer to a few journal articles. No background beyond undergraduate

microeconomics is required, although familiarity with analytical reasoning is assumed.

A) Game theory: a general introduction

The course starts with an introduction to game theory. The distinction between normal form

and extensive form is introduced. The corresponding equilibrium concepts are presented and

discussed. Specifically, we plan to cover the following issues:

1. Static games of complete Information: main solution concepts. Existence theorems. Applications:

models of imperfect competition.

2. Dynamic games of complete information. Representation through extensive form and

backward induction. Subgame perfection. Introduction to repeated games. Applications:

bargaining models.

3. Games of incomplete information and bayesian equilibria.

Textbook: R. Gibbons “A Primer in Game Theory”, 1992, Chapters 1-3.

B) Markets with Private Information

This part of the course analyzes the role of asymmetric information and contracting in market settings. We plan to cover the following issues:

1. Adverse selection. Applications: Competitive screening and signalling in the labor market.

2. Moral hazard. Application: Strategic default in financial markets.Textbook: Mas Colell, A., Whinston M., and J Green “Microeconomic Theory” , 1995; Chapter 13.

B) Social Choice and Mechanism Design

This part of the course presents an introduction to the theories of optimal allocation of resources

in strategic contexts. We plan to cover the following issues:

1. A General Mechanism Design Setting. Vicrey-Clarke-Groves and Bayesian mechanisms.

2. Application: Auction Theory.
