This article discusses analytical developments in the literature on the economics and politics of preferential trade agreements (PTAs). It describes results obtained in the traditional theory that demonstrate the ambiguous welfare outcomes of preferential trade liberalization. Theoretical approaches to designing necessarily welfare-improving PTAs are also discussed. Finally, this article sets out recent analyses in the literature concerning the dynamic expansion of trade blocs, the endogenous determination of policy (relating to preferences within a PTA and to extra-union trade), and the effects of preferential agreements on the multilateral trade system.
