Mixed Taxation and Transboundary Externalities

Abstract

This article concerns income taxation and commodity taxation in a multijurisdiction framework with transboundary environmental damage. The decision problem facing the government in each such jurisdiction is represented by a two-type model (with asymmetric information between the government and the private sector). We show how the possibility to influence the world market producer price adds mechanisms of relevance for redistribution and externality correction which, in turn, affect the domestic use of taxation. Finally, with the noncooperative Nash equilibrium as a reference case, we consider the welfare effects of policy coordination.
