This paper provides general theorems about the control that maxi- mizes the mixed Bentham-Rawls (MBR) criterion for intergenerational justice, which was introduced in Alvarez-Cuadrado and Long (2009). We establish sufficient concavity conditions for a candidate trajectory to be optimal and...

This paper offers a new mechanism in order to Nash-implement a Pareto optimal level of ambient pollution. As usual in the literature on non point source pollution, the proposed scheme is not conditional on individual emissions, since they are not observable; rather it is conditional on aggregate...

Qu’est-ce qu’un économiste ? Un cynique, aurait pu répondre Oscar Wilde, « qui connaît le prix de tout mais la valeur de rien ». Vraie ou fausse, cette affirmation résume assez bien une opinion générale qui s’est exprimée encore récemment lors de la parution en 2010 du rapport...

Chichilnisky's criterion for sustainability has the merit to be, so far, the unique explicit, complete and continuous social welfare criterion that combines successfully the requirement of Weak Pareto with an instrumental notion of intergenerational equity (no dictatorship of the present and no...

Cet article utilise un exemple simple pour passer en revue les concepts de mesure de la biodiversité, avec un effort pour expliciter leurs fondements axiomatiques. L'article offre ensuite un aperçu des concepts développés pour sa protection, et il s'achève sur une dicussion de quelques...

This paper develops a two-country general equilibrium model with endogenous growth where governments behave strategically in the provision of productive infrastructure. The public capitals enter both national and foreign production as an external input, and they are …nanced by a at tax on...

In this paper we test the effectiveness of a compensation mechanism when a negative externality is produced. It allows agents suffering from the negative externality to compensate those who reduce its production. Transfers are implemented via a two-stage design which is an adaptation of...

Bioprospection is, largely, meant to help reducing deforestation and, the other way around, stopping deforestation enhances the prospects of bioprospection. The need for a global agreement to the problem of tropical deforestation has led to the REDD (Reducing Emissions from Deforestation and...

L’objectif de cet article est de montrer comment la recherche en économie aborde et analyse le concept de développement durable, ses significations et ses conséquences. A cette fin, nous avons privilégié un fil directeur qui peut être résumé sous la forme de deux questions : Comment la...
