We study how optimal contracts are modified when the agent has the possibility to acquire information before the contract is offered to him. We consider a situation in which this information is always available to the agent just before producing. Therefore, prior information acquisition is...

This paper proposes a model which intends to analyse the alternative between discrimination and mutualisation in insurance. We suppose there exists an observable (but initially hidden)variable, that predicts the level of risk of an individual. This variable can be observed through a testing...

We examine an important class of decision problem under uncertainty that entails the standarrd portfolio problem and the demand for coinsurance. The agent faces a controllable risk -his demand for a risky asset for example- and a background risk. We determine how a change in the distribution in...

Cet article traite des relaions entre un principal, quie veut se procurer un bien, et les deux agents impliques dans le processus de production de ce bien. Les couts des agents constituent une information privee. Le principal confie la production du bien fini a l'un des agents, qui en...

In three-tier principal-agent models, there is foten concern about the risk of collusion between the supervisor hired by the principal to deal with the agent, and the agent. A collusion-proof contract is often optimal, altough the literature has produced some situations in which collusion is...

This paper studies to what extent economic integration, or globalization, influences the accountability of politicians, In a framework the politicians are only controled through reelection rules, we study the effect of economic integration on the reelection rules chosen by the voters and try to...

In this paper we show how the order of Linear Stochastic Dominance proposed by Gollier (1995) can be applied to situations with dependent risky assets.

L'objet de cet article est de presenter une synthese de la litterature theorique concernant les interactions entre strategies financieres et strategies de production.

We investigate in this paper the attitude towards risk of bettors in British horce races. The model we use allows us to go beyond the expected utility framework and to explore various alternative proposals by estimating a multinomial model on 34443-race dataset. We find that rank-dependant...
