The paper studies the setting of optimal fiscal policy in a second-best world with environmental externalities. The optimal second-best pollution tax is shown to lie below the first-best Pigovian tax, particularly if substitution between labor and polluting intermediate inputs is easy, the labor...

Jaffe and Palmer (1997) present three distinct variants of the so-called Porter Hypothesis. The “weak” version of the hypothesis posits that environmental regulation will stimulate certain kinds of environmental innovations. The “narrow” version of the hypothesis asserts that flexible...

Il est de coutume d'associer à la protection de l'environnement l'idée que l'intervention des pouvoirs publics représente uniquement des coûts supplémentaires pour les agriculteurs. Cependant, depuis quelques années, ce paradigme est remis en cause par de nombreuses études. Par exemple,...

This paper examines the choice between alternative trade-based approaches to reducing global environmental damage, such as trade-related process standards and tariff-based approaches. Estimates of the effects of alternative policies are presented, using a calibrated global trade model with...

"The global environment is a matter of great importance to all nations.... Yet differences of opinions prevail about the main problems, and about the institutions to manage cooperation....The problem of finding carbon abatement policies is complicated by the scientific uncertainty about the...

Total factor productivity growth (TFPG) has been traditionally associated with technological change. We show that when a factor of production, such as energy, generates an environmental externality in the form of CO₂ emissions which is not internalized because of lack of environmental policy,...

We provide a new formulation of the Porter hypothesis that we feel is in the spirit of the hypothesis. Under this formulation we find that the Porter hypothesis need not hold universally, and identify conditions under which it may or may not hold. We first consider the case where the abatement...
