Sélection adverse et aversion pour le risque

  • Bernard SALANIE

The purpose of this paper is to study a simple example of an adverse selection problem in a Principal-Agent relationship, where uncertainty is not resolved at the time the contract is signed. It is shown that the agent's risk-aversion then plays a critical role in determining the shape of the optimal contract; more precisely, a bunching phenomenon will occur for large (but finite) values of the agent's absolute index of risk-aversion. Since this phenomenon is absent in the two extreme cases of zero or infinite risk-aversion, it is argued that one would miss important points in focussing on these (simpler) cases, as is usually done.
