Trade Sanctions and Green Trade Liberalization

Abstract

This paper studies the impact of a WTO withdrawal of trade concessions against countries that fail to respect globally recognized environmental standards. We show that a punishing tariff can be effective when environmental and trade policies are endogenous. When required standards lie within a reasonable range, compliance along with free trade as a reward is the unique equilibrium outcome. A positive optimal tariff in the case of non-compliance prevents pollution-motivated delocation, but only works as a successful credible threat and does not emerge in equilibrium. Results are consistent with broad empirical evidence that disputes the pollution haven hypothesis and suggests capital movements to be non-pollution related.Environmental Policy, WTO, Delocation, Tariffs, Credible Threat
