This publication presents results of a year-long research program initiated by the National Commission for Employment Policy to research and discuss the employment effects of the North American Free Trade Agreement (NAFTA). It contains the letter to the President in which the Commission endorses NAFTA because of its positive employment-creating effects and makes recommendations on worker adjustment assistance programs that address the adverse employment effects of NAFTA and on migrant and seasonal farmworker programs that address the short-term increases in Mexican immigration likely to result from NAFTA. Three commission-sponsored studies are appended. "A U.S.-Mexico-Canada Trade Agreement: Sectoral Employment Effects and Regional/Occupational Employment Realignments in the United States" (Robert Stern and others) reports a study to estimate changes in employment that will be required across sectors, occupations, and locations within the U.S. economy. Sectoral effects and employment changes are illustrated in 44 tables. "The Impact of the NAFTA on U.S. Regional and Sectoral Labor Markets" (DRI/McGraw-Hill) presents results of three simulation exercises designed to measure the potential impact of NAFTA on the U.S. economy and on employment levels within 9 U.S. geographical regions and 19 manufacturing and 6 nonmanufacturing industry sectors. Net impacts of gradual and nongradual scenarios are depicted in 94 tables. "NAFTA, Migration, and U.S. Labor Markets" (Philip Martin) reports an analysis of effects of NAFTA based on a qualitative assessment of three major factors responsible for Mexico to U.S. migration: demand-pull, supply-push, and network of friends and family.
