We consider an overlapping generations model with environment, where we introduce an elastic labor supply. In this framework, consumers have to choose between consumption, environmental quality and leisure. We establish that several steady states can coexist, even under a Cobb-Douglas...

We consider an overlapping generations model with environment and an elastic labor supply. In this framework, consumers have to choose between consumption, environmental quality, and leisure. We show the existence of both deterministic cycles and indeterminacy. In contrast to previous results,...

Nous étudions expérimentalement le comportement de sujets confrontés, dans une population, à une multiplicité de jeux du dilemme du prisonnier, suivant que les interactions sont bilatérales ou multilatérales. Nous observons, (i), une coopération significativement supérieure en cas de...

In this article, we study the question of intergenerational equity in a framework that displays two kinds of agents distinguished by their non dynastic intergenerational altruism. The more altruist agents regarding the transmitted environment are qualified of ecologists, whereas the others, less...

Since the publication of the Brundtland Report more than 20 years ago, sustainable development became always more popular. If it is probably necessary to operationalize it more effectively in order to foster its daily perception by people, sustainable development remains a soft concept since the...

[fre] Bien que la France ait écarté jusqu’ici l’idée de recourir à des instruments incitatifs pour réduire la pollution diffuse aux nitrates, cet article revient sur le potentiel de ces instruments tels qu’ils ont été employés par certains de nos voisins européens ou, à défaut,...

[eng] Based upon a critical review of various works about nitrate NPS pollution, we show that in the debate opposing price vs. quantity instruments to regulate pollution, it is possible to refine — and even more to go past — the measures which fail to reduce pollution, but at a significantly...

Nous présentons un modèle "prospectif" avec deux économies à générations imbriquées : L'une, riche, a stabilisé son stock de gaz à effet de serre dans un passé récent, alors que l'autre, pauvre, entâme une phase d'émissions croissantes sans moyen de lutter contre. Ces externalités...
