The efficiency of the Pigouvian tax suggests that price-based regulation is the proper benchmark for efficient regulation. However, results due to Carlton and Loury (1980, 1986) question this; when harm depends on scale effects a pure Pigou tax is inefficient regulation in the long run. In this...

It seems popular to teach that a Pigouvian tax is efficient. This strongly suggests that price-based regulation is the proper benchmark for efficient regulation. However, results due to Carlton and Loury (1980, 1986) question this; when harm depends on scale effects a pure Pigou tax is...

In this paper we analyze a simple environmental tax in Edgeworth-Bertrand duopoly with soft capacity constraints and argue that the mode of strategic interaction is co-determined by taxation. Although the capacity constraint gives rise to a non-convexity it is possible to find efficient taxes....

In this paper we investigate environmental regulation by taxes and quotas in the context of a monopolistically competitive industry. Firstly, we find the combination of a quota and a tax supporting the first best solution. Secondly, we explain why the allocative equivalence between the two...
