This paper presents an analysis of environmental policy in imperfectly competitive markets. We investigate how environmental taxes should be optimally levied in a precommitment policy game and their e§ects on social welfare. The paper also examines the potential impacts of the regulatorís environmental conscience on policy setting. We start the analysis with a benchmark model where all players are environmentally dirty in themarketplace. We then extend the model to the case in which the market is composed of a mix of dirty and clean strategic players. We show that, in both cases, the regulator must necessarily trade o§ between regulation of environmental quality and the industry production ine¢ ciency problems. Furthermore, the results show how higher levels of concern for environmental issues outweigh the under taxation problem that arises in order to avoid further reductions in welfare. Finally, we show that the existence of clean players produces positive social externalities. Under an ex ante environmental policy game, higher social welfare outcomes are possible.
