Abstract

In this article we integrate two topics in international trade policy that have received (separately) a lot of attention: the effects of regional trade blocs, and export pessimism regarding poorer countries. The specific issue that allows us to bring together these questions is whether regional integration adversely affects non-members. We use quarterly data on bilateral trade flows for the period 1990 through 1997 to examine U.S. imports from its NAFTA partners as well as from non-NAFTA trade partners, and more specifically, those countries expected to be hurt by NAFTA. Two measures are used: "import penetration" or imports from a particular source as a share of US GDP, and the income elasticity of expenditure on imports from a particular source. Both "import penetration" and the income elasticity of expenditure affect the export earnings of U.S. trade partners, a matter of particular concern for developing countries.The broadest pattern observed in the income-expenditure elasticities is clear evidence of increased penetration by non-oil developing countries. This is in marked contrast to the stable GDP share and expenditure elasticity for developed country imports. Regional results suggest that the Caribbean and the East Asian NICs were the only area groupings that experienced a reduction in income-expenditure elasticity. But overall on the basis of U.S. income-expenditure elasticities it appears that the first four years of NAFTA were associated with trade expansion rather than trade diversion.
