Ce papier aborde la question de la subsidiarité dans le cadre de la Politique Agricole Commune. L'instrument privilégié est ici un contrat de gel de terre dont la définition relève soit directement des instances de l'Union Européenne, soit des instances nationales. Dans ce dernier cas, dit...

Dans le cadre d'un modèle à générations imbriquées, nous supposons que la gestion d'une ressource renouvelable correspond à l'émission de quotas d'exploitation transférables. Chaque agent a la possibilité d'utiliser les quotas dans la production ou de les vendre à la génération...

We study a model with an exhaustible resource and a substitute which is not a backstop technology. We focuse our attention on the optimal policy of consumption which is described by a Ramsey's rule as in the seminal paper of Dasgupta and Heal [1974] but with a discount rate which is not always...

We consider a model of regulation for nonpoint source water pollution through non-linear taxation/subsidization of agricultural production. Farmers are heterogenous along two dimensions, their ability to transform inputs into final production and the available area they possess. Asymmetric...

This model deals with the greenhouse effect, that is to say with a problem of international pollution. Through a description of the bargaining process, it aims to determine the different forms that may be taken by cooperation agreements between the countries involved. We demonstrate, in...

Endogenous growth is generally built on a positive externality hypothesis which is the opposite of a negative externality caused by pollution. We study a linear technology with simple assumption: an aggregate capital stock which represents a learning by doing effect and a pollution flow...

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...

We study, in a simple model, the partial equilibrium of an industry with n firms endowed by different technologies which have different pollution effects. The price of input (labour) and the demand curve to the industry are given. Pollution is restricted by a tradable market of permits in the...
