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...

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...

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...

To comply with laws, regulations and social demands, polluting firms 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...

Pollution abatement goods and services are now largely being delivered by a specialized "eco-industry." This note reconsiders Pigouvian taxes in this context. We find that the optimal emission tax will depart from the marginal social cost of pollution according to the polluters' and the...
