Paper presented at the Northeastern Agricultural and Resource Economics Association's Annual Meeting, Bar Harbor, ME, June 10-12, 2001 Data for 1989-99 indicate that U.S.-Mexico trade has increased substantially under NAFTA. Regression analyses do not provide strong evidence that NAFTA has been an mportant factor since the data indicate a continuation of previous trends. NAFTA resulted in trade under TRQs for previously prohibited products and enabled other trade to continue increasing.
