Recent surveys report the increasing number of muddy flows in many areas, and point out the fact that agricultural practices (among others) influence significantly the risk and severity of muddy flows. In this paper, we investigate the economic incentives that can be given to the farmer to adopt...

Through the Water Framework Directive, the European Commission urges its Member states to reach a level of "good status" of water for 2015. This level can be different from the regional first-best. Neither the supra-regional regulator (European Commission) nor the regional regulator (Member...

Prévention et précaution sont deux concepts bien différents, même si le premier peut être considéré comme un cas particulier du second lorsqu'aucune nouvelle information ne doit arriver dans le futur. Néanmoins, les deux concepts se rejoignent lorsqu'il s'agit d'envisager les problèmes...

In this paper, we investigate an audit policy that allows a regulator to control past declarations of an agent who is caught to fraud in the current period or to adopt an action that is not desirable for Society. Coupled with redistribution effects due to the production of a public good, we show...

Compte tenu de l'information incomplète dont on dispose quant aux pratiques culturales des exploitants agricoles, il n'est pas toujours optimal de baser les politiques de lutte contre la pollution d'origine agricole exclusivement sur un mode de taxation. Symétriquement, un système...

The current international regime that regulates maritime oil transport calls for financial contributions by oil firms once an oil spill has occurred. Their percentage contribution to the International Oil Pollution Compensation Fund depends only on their level of activity. In this paper, we show...

In this paper, a manager borrows external funds in order to invest in production and also in prevention. The latter action must reduce the environmental risk driven by the activity of the firm. Prevention is observable neither by outside lenders nor by institutions such as environmental agencies...

The maritime oil transport is regulated by the 1992 Civil Liability Convention for Oil Damage and the 1992 Oil Pollution Compensation Fund. In this compensation regime, contributions of oil firms are based on the aggregate risk of the Fund and are assessed each time an oil spill is registered....

Dans cet article nous construisons un système de contrôle des émissions polluantes qui combine permis d’émission et taxes sur la base du modèle de Roberts et Spence (1976). Nous relâchons l’hypothèse de linéarité de la fonction de transferts monétaires entre le régulateur et les...

This article offers some economic insights for the debate on the reversible geological disposal of radioactive waste. Irreversibility due to large sunk costs, an important degree of flexibility and several sources of uncertainty are taken into account in the decision process relative to the...
