The goal of the course is to study a number of important results of the Theory of Contracts and Incentives. We focus mainly on the classical static models at the beginning and introduce dynamic theories at the end. The first part is devoted to Principal-Agent Theory in various contexts: under pure moral hazard; in the pure adverse selection case. In the second part we study multi-agent models: incentives in teams; yardstick competition; tournaments. The third part is an introduction to dynamic theories: implicit contracts under complete information; relational contracts; repeated principal-agent relationships.
