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....

We consider a firm under strict liability that must choose between two risky technologies, one being safer but costlier than the other one. The total potential level of damage increases with the level of activity. We show that, under limited liability, technological change is welfare improving...

Through the Water Framework Directive, the European Commission urges its Mem- ber 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...

How people develop beliefs about themselves (self-theories) plays an important role on motivation and achievement as shown by Carol Dweck’s life-long research. In this paper, we conduct a field experiment to investigate whether self-theories impact overconfidence and risk taking. Self-theories...

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...

In this paper, we analyze the choice of primary prevention made by individuals who bear a risk of being in bad health and an additive risk (of complications) that occurs after a disease has been diagnosed. By considering a two argument utility (depending on wealth and health), we show that the...

In this paper, we focus on the adverse selection issue that prevails in an economy when the regulator is not able to observe the type of the abate- ment costs of the firms. The regulator decides the total level of emission that minimizes the total social cost and he sells them to the firms at...
