The United States-Mexico-Canada Agreement (USMCA), a modified and modernized version of the North American Free Trade Agreement (NAFTA), will continue to govern most economic relationships in North America, including the more than $1.3 trillion in annual regional trade in goods and services, for the foreseeable future. USMCA preserves the bulk of the NAFTA structures that permit North American manufacturers to compete effectively with their European and Asian counterparts in North American and foreign markets. Once in effect, USMCA should largely resolve the chilling effect on investment and new hiring generated by three years of uncertainty over NAFTA’s future. This book provides a detailed analysis and critique of the provisions of the USMCA and the USMCA’s relation to NAFTA. It is designed to assist lawyers and non-lawyers alike, including law, economics and public policy scholars, business professionals and governmental officials who require an understanding of one of the worlds’ most economically and politically significant regional trade agreements.
