We provide a new price-quantity mechanism to implement the Lindahl allocations as Nash equilibria. We show that it satisfies the property of forthrightness, introduced by Saijo et al. [1996]. Thus, at a Nash equilibrium, each player reports directly and honestly his personal price and his demand...

This paper deals with the existence of anonymous mechanisms to realize the Lindahl correspondence. We consider, in turn, constant and decreasing returns to scale technologies for producing public goods. In each case, we provide a continuous (but not smooth) and weakly balanced mechanism, which...

We study the management of a multispecies fishery, exploited under a non-selective harvesting technology. We construct an economic mechanism to regulate the fishery. Under a large class of models, capable of accounting for imperfect competition, congestion externalities, pro-social motivations...

This paper considers the issue of a catastrophic environmental collapse and the way one should deal with it. In the model used here, one faces the choice to cross or not a critical threshold of pollution, which consequences are a definitive destruction of some environmental characteristic. The...

In this note, we discuss the existence of anonymous and balanced mechanisms to implement the Lindahl allocations. We obtain an impossibility result for the class of mechanisms defining an homeomorphism between the message space and the allocation space.

This paper presents a new economic mechanism, such that the associated game form implements Lindahl equilibria as Nash equilibria. Each player sends a 2-dimensional message, in order to tell his marginal propensity to pay and his demand for the public good. At a Nash equilibrium, the players...

This note provides an additional argument in favour of the use of a negligence rule in tort law. When the probability of suit varies among injurers and is not observable by the judge, the judge will fail to implement the socially optimal level of care using a strict liability rule (for this...

[fre] La politique du climat nécessite une décision en situation d'incertitude radicale. Ce document illustre ce débat en supposant l'existence d'un risque de catastrophe irréversible au-delà d'un seuil critique de pollution connu. Sans apprentissage, la décision optimale consiste à...

Climate policy claims a reflexion about public decisions under uncertainty. This work focuses on the case where a risk of catastrophe of unknown range is anticipated for pollution levels greater than a certain critical threshold. If constrained by the initial information, the best decision is to...
