Using a common agency framework, we characterize possible equilibria when annuities contracts are not exclusive. We discuss theoretical and empirical implications of these equilibria. First, we show that at equilibrium prices are not linear. Then we characterize an equilibrium. We provide...

In this note we show that the equilibrium characterized by Biais, Martimort and Rochet (Econometrica, 2000) could have been characterized by direct mechanisms even if the Revelation Principle does not apply in their setting. The use of more sophisticated mechanisms, such as menus, was not necessary.

In multiple-principal multiple-agent models of moral hazard, we provide sufficient conditions for the outcomes of pure-strategy equilibria in direct mechanisms to be preserved when principals can offer indirect communication schemes. The conditions include strong robustness in the direct...

In this note we argue that in Common Agency games, the restriction to deterministic menus is crutial.We give an simple example (complete information, no moral hazard) in which an equilibrium is not robust to the introduction of stochastic menus.

In common agency games, one cannot characterize all equilibria by considering only direct mechanisms. In an attempt to overcome this difficulty, Peters [Econometrica, 2001] and Martimort and Stole [Econometrica, 2002] identified a class of indirect mechanisms (namely, menus) which are able to...

We study the relations between compensation schemes and risk aversion of managers in a strategic framework. We first show that the use of relative performance evaluation (RPE) in compensation contracts reduces the equilibrium profits of Cournot firms if managers are not too risk averse. Second,...

It is argued that the revelation principle in multi-principal multi-agent games cannot be generalized. In other words, one cannot restrict attention to incentive compatible mechanisms, even if the concept of information is enlarged.

A the present paper we show that messages may improve efficiency even in model of complete information. Messages are useful two main reasons. First, if the principal is not allowed to use stochastic mechanisms, mechanisms with messages can induced mixed strategies and hence indirectly a...
