In September 1993, the United States Congress formally ratified the North American Free Trade Agreement (NAFTA) in conjunction with the legislatures of Canada and Mexico. NAFTA phases out tariff barriers between the United States, Canada, and Mexico over a period of several years. The primary purpose of this study is to provide an empirical tool for evaluating the effects of NAFTA on beef trade between Canada, Mexico, and the United States. Trends were identified in U.S. beef exports and imports to Canada and Mexico over a period of several years. From the data on import/export quantities and prices, relevant elasticities were estimated for the the three trading partners using a partial adjustment modeling technique. Given the elasticities, relevant statistical tests were performed to determine the significance of price and quantity changes. This was done to determine whether changes in trading practices were consistent. Finally, policy recommendations were developed based on the assessment of NAFTA on U.S. beef trade. An overall direction of trade among the three countries was determined. Policies and implications based on economic theory were developed.
