New Regionalism

Three decades ago regionalism and free trade arrangements swept developing countries, but expectations of economic development through regional integration were not realized and these arrangements were judged a failure. As the GATT process falters many countries are turning again towards bilateralism, but the success of trade liberalization under the GATT and by many developing countries acting unilaterally has weakened the case for regionalism. In Discussion Paper No. 715, Research Fellows Jaime de Melo and Dani Rodrik, with Arvind Panagariya, assess whether regionalism can accomplish more than unilateral trade liberalization (UTL) and whether such integration may be a step towards freer world trade. They find that a Free Trade Area (FTA) will be more trade-creating, the higher the initial tariff, the lower the post-union tariff on third countries and the greater the complementarities in partners' import demands. Quantitative restrictions always allow the design of an FTA that is welfare- improving for members with no net effect on non-members, but the intra-bloc compensation schemes this requires have often been distortionary in past FTAs. With high protection between blocs, a small country may prefer to join a bloc, but scale economies do not provide a rationale for regionalism in themselves.

The authors consider three channels through which regional integration affects decision-making to examine the costs and benefits to countries of surrendering autonomy to supranational authorities: `preference-dilution', where a regional arrangement reduces the role of lobbying and enhances efficiency; `preference-asymmetry', because members' different preferences and economic structures have indeterminate effects on efficiency; and enhanced efficiency if integration allows the design of institutions from scratch. De Melo, Panagariya and Rodrik find no statistical evidence of higher growth among countries that integrated during the first wave of regionalism, but history need not repeat itself, provided countries delegate real authority to well-designed new regional institutions that do more than respond to pressure groups.
