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....

We first point out that, using any of the current criteria for comparing information systems in principal-agent models with moral hazard (such as Kim (1994)'s criterion), it is often impossible to contrast the value of information obtained from different policies of contingent audits that bear...

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...

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...

We examine the e®ect of an emission tax when the abatement good or service is supplied by an imperfectly competitive eco-industry with free entry. We show that a higher tax always increases the number of ¯rms in the eco-industry whereas it has an ambiguous e®ect on indi- vidual and total...

The welfare implications of a merger in an environment industry (i.e. the industry that supplies abatement goods and services) are considered in a Cournot-Nash context. The traditional analysis of mergers is extended in two ways. First, we examine how the environmental policy may affect the...

Cet article étudie avec un regard nouveau la subvention environnementale lorsque les pollueurs achètent leur bien ou service de dépollution auprès d’une industrie spécialisée, dite éco-industrie. L’éco-industrie est ici oligopolistique. Le régulateur est donc confronté à une...

The objective of this paper is to highlight some of the most important implementation issues associated with the greening of global value chains (GVCs). Special attention is given to how public policies and business strategies can support each other in meeting the challenge, particularly in...

La responsabilité sociale et environnementale de l'agriculture et des entreprises agro-alimentaires est aujourd'hui largement remise en question. Ce secteur économique est à la croisée des chemins compte tenu des nombreuses externalités environnementales de l'activité du secteur, des...

Most governments acknowledge nowadays the strategic importance of the environmental goods and services industry (or eco-industry), in the new economy centered on knowledge, innovation and environmental protection. However, the underlying dynamics of this booming sector is still poorly...
