Contesting an international trade agreement

Abstract

We develop a new theoretical political economy framework called a ‘parallel contest’ that emphasizes the political fight over trade agreement (TA) ratification within countries. TA ratification is inherently uncertain in each country because anti- and pro-trade interests contest each other to influence their own government's ratification decision. As in the terms-of-trade theory of TAs, the TA removes terms-of-trade externalities created by unilateral tariffs. But, a TA also creates new terms-of-trade and local-price externalities in our framework due to endogenous ratification uncertainty combined with the requirement that each country ratify the TA for it to go ahead. Thus, reciprocal TA liberalization fails to eliminate all terms-of-trade externalities.
