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...

To comply with laws, regulations and social demands, polluting increasingly purchase the needed means from specialized suppliers. This paper analyzes this relatively recent phenomenon. We show how environmental regulation, the size of the output market, the elasticity of demand for abatement...

The objective of this paper is to examine the joint effect of the board of directors and the auditor on the severity of sanctions imposed by the financial authority. Based on a theoretical model and using a unique dataset, we find that the board of directors and its audit committee play a...

This article examines the relationship between the enforcement strategy chosen by an Environmental Protection Agency and the organization of a firm. Under plausible assumptions it is shown that if the Agency ignores the firm's incentive system, then the firm cannot be decentralized. Cet article...

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...

We propose a dynamic graph-theoretic model for ecosystem management as a control over networked system composed of target nodes and unmarked nodes. The network is represented by a complete graph, in which all vertices are connected by a unique edge. Target nodes are attracted by the objective...
