This paper considers the welfare and policy implications of a merger between environment fi rms (i.e., firms managing environmental resources or supplying pollution abatement goods and services). The traditional analysis of mergers in Cournot oligopolies is extended in two ways. First, we show...

L’auteur étudie les conflits d'objectifs entre une agence environnementale et une autorité de la concurrence dans un duopole asymétrique. Il examine les cas où l'autorité de la concurrence peut s'opposer à une taxe environnementale afin d'éviter la position dominante d'une firme et pour...

The aim of this paper is to compare different environmental policies for cost-effective habitat conservation on agricultural lands, when the desired spatial pattern of reserves is a random mosaic. We use a spatially explicit mathematical programming model which studies the farmers' behavior as...

The paper aims to study the effects of reducing pesticide use by farmers in the arable sector in France and the feasibility of a policy target of reducing pesticide use by half. The originality of the approach is to combine statistical data and expert knowledge to describe low-input alternative...

We model environmental interaction among countries as a policy game where governments in each country use quotas or taxes as strategy variables. The environmental policy has a triple role to play: targeting domestic emissions, providing strategic advantages for domestic firms and targeting...

We study the welfare-theoretic consequences of diverging social and private time-preference rates and time-to-build for the transition to a low-carbon energy industry. We show that time-to-build, a prevalent characteristic of capital accumulation in the energy sector, amplifies the distortion...

Face aux puissants mécanismes de marché poussant à la concentration spatiale des filières animales, les mesures environnementales peinent à réduire les excès d’azote dans les territoires à forte densité animale. La montée du prix de l’énergie et la dérèglementation des...

The Green and Blue infrastructure (Trame verte et bleue ?TVB) is a new conservation policy tool based on the notions of ecological network and corridor. The TVB's implementation process establishes the connection of multi and nested decisional and action levels and needs permanent adjustment to...

A three-stage game of production technology, signal and price competition is developed to study the impact of eco-labeling, in a duopoly model of vertical product differentiation. The production technology and the subsequent pollution level are non-observable by consumers. The only way to inform...

This paper extends the literature on the taxation of polluting exhaustible resources by taking international heterogeneities and national tax-setting into account. We propose a two-country Romer model of endogenous growth in which the South is endowed with the stock of an essential polluting...
