This paper proposes an equilibrium approach to belief manipulation and deception in which agents only have coarse knowledge of their opponent s strategy. Equilibrium requires the coarse knowledge available to agents to be correct, and the inferences and optimizations to be made on the basis of...

The article shows how Jean-Francois Mertens contributed to the development of game theory and microeconomics as we know them today. Along with about 80 articles, Mertens's topics go from the formulation of Bayesian decision making in games with incomplete information to the foundations of cost...

We are given a list of tasks Z and a population divided into several groups X j of equal size. Performing one task z requires constituting a team with exactly one member x j from every group. There is a cost (or reward) for participation: if type x j chooses task z, he receives p j (z);...

Contrary to most countries, the recruitment of assistant professors in France is centralized: recruitment committees submit a ranking of candidates to the Ministry of Education, the candidates submit their own ranking over the faculties that rank them and the Ministry compute the final match...

We consider the asymptotic value of two person zero sum repeated games with general evaluations of the stream of stage payoffs. We show existence for incomplete information games, splitting games and absorbing games. The technique of proof consists in embedding the discrete repeated game into a...

The present paper contributes to the body of knowledge on search frictions in credit markets by demonstrating their ability to explain why the net interest margins of banks behave countercyclically. During periods of expansion, a fall in the net interest margin proceeds from two mechanisms: (i)...

We study a first price auction preceded by a negotiation stage, during which bidders may form a bidding ring. We prove that in the absence of external effects the all-inclusive ring forms in equilibrium, allowing ring members to gain the auctioned object for a minimal price. However, identity...
