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...

To comply with laws, regulations and social demands, polluting firms increasingly purchase the needed means from specialized suppliers. This paper an- alyzes 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...
