We study a duopoly on a market with horizontal differentiation where firms compete in catalog : firms choose a price and a location in the consumer? space. Whereas there is no equilibrium in pure strategy for the simultaneous game, we show that an equilibrium always exists in a sequential...

This paper reexamines the issue of relative versus joint incentive schemes in a multi-agent moral-hazard framework. The model allows a full analysis of the information and dependence structure. An important result is that the widespread notion that greater correlation in outcomes calls for more...

We study the stockholder-manager relationship in a firm when an illicit strategy can be followed. We derive the optimal compensation offered by the firm and examine how it affects the ceo?s action. We then discuss the optimality of stock-options or free-stocks. Moreover, we analyze the link...

In a Hotelling's duopoly with a general transportation cost function, we study competition through catalog: each firm chooses at the same time a price and a location. With simultaneous catalog offers, there is no equilibrium in pure strategies for high valuations of the consumers, while a...

Nous étudions un duopole sur un marché où les produits sont différenciés horizontalement. Les firmes se font concurrence en catalogue dans le sens où elles choisissent simultanément un produit et un prix. Nous montrons alors qu'il n'existe pas d'équilibre de Nash en stratégie pure en...

It has been shown by Maskin and Tirole (1990, proposition 11) that with quasi-linear preferences and private values, an informed principal neither gains nor loses if her private information is revealed before contracting takes place. The note shows that this result may not hold when the agent...

This paper studies communication mechanisms for two players with symmetric single-peaked preferences. The peaks are privately known and drawn from a uniform distribution before the agents take a collective decision. While for the general setting Moulin (1980) characterized all strategy-proof...
