Cet article etudie la question des permis de pollution dans le cadre d'un modele a generations imbriquees: la pollution resulte de l'utilisation de l'environnement dans le processus de production et constitue un externalite negative qui vient diminuer l'utilite des agents.

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 develops a two-sector overlapping generations model in which one sector produces an externality on the environmental quality and the other has no effect. We assume that environmental quality degradation results from production activity of one sector. Then, we characterize the...

Kimball [1990] developps a theory of prudence isomorphic to Pratt [1964] and Arrow [1965] theory of risk aversion. Nevertheless, if the Arrow-Pratt risk aversion index determines behavior in risk, it is not always the case for prudence. Moreover, concept of prudence and precautionary behavior...

This paper presents an overlapping generations model of environmental externalities with a depollution technology. We show that if an agent is sufficiently risk averse, voluntary contribution is a decreasing function of average efficiency of depollution technology. If on the contrary, the...

En considerant que l'une des caracteristiques des problemes environnementaux est le niveau d'incertitudequi les accompagne, nous proposons d'etudier les effets de ces incertitudes sur les comportements de choix de portefeuille et d'epargne des agents. Nous montrons alors qu'a l'equilibre...

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...
