How Preferential Trade Agreements (PTAs) Affect Non-Members.

Since the conclusion of the Uruguay Round in 1994, participation in preferential trade agreements (PTAs) has proliferated rapidly. In 1990, there were only about 70 PTAs in force. By 2010 the number of PTAs increased to almost 300. On one hand we have known since Viner (1950) that PTA formation could potentially reduce world welfare. More recently, concerns have arisen in the literature specifically about implications for the welfare of nonmembers. Chang and Winters (2002) was the first paper to provide empirical evidence of the adverse effects of PTAs on the welfare of excluded countries through the terms-of-trade effects that are generated. On the other hand there is also evidence that PTAs can lead to further unilateral liberalization by governments particularly in developing countries. The following papers contribute to this debate.
