The paper analyzes the efficiency of extended producer responsibility (EPR) for waste management. We consider a vertically differentiated duopoly where endogenous market quality affects waste disposal costs. Each producer has to meet a take-back requirement that forces it to collect and treat...

En adoptant le point de vue du régulateur, nous cherchons à répondre aux questions suivantes : quel est le rôle des AV aujourd'hui dans un contexte où les firmes s'engagent dans la RSE ? RSE et AV sont-ils des substituts ou des compléments du point de vue de la puissance publique ? Quelle...

Does self-regulation improve social welfare? We develop a policy game featuring a regulator and a firm that can unilaterally commit to better environmental or social behavior in order to preempt future public policy. We show that the answer depends on the set of policy instruments available to...

Are Corporate Social Responsibility and Voluntary Agreements Complementary ? Voluntary agreements between regulators and firms have been in use for at least two decades. In recent years, however,firms have tended to commit to better environmental or social behavior in a more unilateral fashion....

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...

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...
