Changing Economic Openness for Environmental Policy Convergence: When Can Bilateral Trade Agreements Induce Convergence of Environmental Regulation?

Abstract

Citizens’ concerns about (international) environmental protection standards are of increasing importance to governments in industrially advanced, high-regulating countries. In almost any proposal for a trade agreement, countries with low environmental regulation standards are required to introduce higher policy standards in exchange for high-regulating countries dismantling their trade barriers and granting access to their domestic markets. Low-regulating countries often act as required and introduce legislation aimed at reducing pollution. This leads to declaratory or de jure policy convergence. But such legislative action is not always associated with de facto or actual policy convergence, since policies are not always enforced. To analyze the strategic aspect of this potential “slippage,” we set up a game-theoretic model with imperfect information. In the model, a high-regulating and a low-regulating country negotiate a bilateral free trade agreement with environmental provisions. We show how potential gains from trade, policy enforcement, and reputation costs, as well as domestic demands for environmental protection affect the occurrence of environmental policy convergence through conditional trade agreements. This study thereby advances our understanding of the relationship between bilateral trade and convergence of environmental policies.
