This paper presents an overlapping generations model of environmental externalities with a depollution technology. each agent concerned by the environmental degradation can volutary contribute in order to reduce it. Contributing to the environmental quality means financing depollution activities...

Cet article presente les principaux resultats d'une mise en oeuvre critique de la methode d'evaluation contingente, realisee dans le cadre d'un programme de recherche engage par le GIP-hydrosystemes en 19995. Il s'appuie sur une enquete d'evaluation contingente menee aupres d'un certain type...

Lorsque le question de valorisation utilisee dans la methode d'evaluation contingente prend la forme d'une question fermee, le modele econometrique adequat est un modele a choix binaire. Dans cet article, nous presentons un modele a choix binaire tenant compte d'une heterogeneite par groupes de...

We analyze the effect of a constant debt policy on capital accumulation and provide an indepth treatment of the dynamics in the economy of Diamond. We derive the conditions for avoiding a debt crisis in both the short-run and the long-run and provide geometrical tools to analyze the issue of...

This paper provides sufficient conditions for the existence of pure strategy Nash equilibrium in a class of games of group formation. The use of potential allows for a characterisation of such an equilibrium.

This paper constructs an overlapping generations model of pollution externality wherein individuals are altruistically linked to their offspring as in Barro (1974). It is shown that steady state consumption may be a decreasing function of the intergenerational degree of altruism. Despite...

This paper studies within a dynamical model how decentralized individuals happen to elect non-proprietary standard. The issue is coordination because the individual benefit of adoption depends on whether other agents elect to adopt the same standard. It shows that whenthere are increasing...
