Natural areas are essentially multifunctional, contributing in multiple ways to human well-being. Ecosystem goods and services are provided through ecosystem func- tions (regulation, habitat, production and information). Among the multiple services provided by natural areas, recreational...

This paper re-examines environmental regulation, under the assumption that pollution abatement technologies and services are provided by an imperfectly competitive environment industry. It is shown that each regulatory instrument (emission taxes and quotas; design standards; and voluntary...

This paper considers the environmental policy and welfare implications of a merger between environment firms (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....

Les auteurs reconsidèrent la réglementation environnementale, sous l'hypothèse que les technologies et services de réduction de la pollution sont offerts par des entreprises spécialisées formant un oligopole. On y montre que chaque approche réglementaire (taxes et quotas sur les...

Depuis une dizaine d'années, les grandes entreprises polluantes ont été de plus en plus nombreuses à adopter une attitude active face à la protection de l'environnement. Ces initiatives des industriels en matière d'environnement ont pris le nom d'approches volontaires. Le recours croissant...

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...

This paper examines the effect of emission taxes on pollution abatement and social welfare, when abatement goods and services are provided by a Cournot oligopoly with free-entry. We point out initially that a higher tax not only increases demand for abatement; it also makes polluters less...

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...

This paper re-considers environmental subsidies in the context where polluting firms procure their abatement goods and services from a specialized oligopoly. In order to maximize social welfare, a regulator must then simultaneously alleviate two distortions: one that comes from pollution and the...
