Economics of Risk

Objectifs

The course is divided into 2 parts. In the first part, we will study choices in a context of risk, and apply the theoretical results to several fields of application: insurance, finance and public decision-making. In the second part, we will extend our analysis to choices in an uncertain context, with an introduction to strategic uncertainty.
