Free trade and the greening of domestic industry

In this paper we present an example where a domestic import-competing industry can benefit from a pollution tax borne by its consumers. We show that this pollution tax can be similar to a traditional trade barrier (such as a tariff) and can raise the price received by the domestic industry. Given an open economy, we highlight conditions under which domestic producers prefer a higher consumption-based pollution tax than is socially optimal. In contrast, when the economy is closed, we find that producers prefer a pollution tax that is lower than socially optimal. Domestic producers turn ‘green’ only when faced with import competition.
