It identifies demand elasticities by developing a difference in differences based method that exploits the fact that the additional wedge driven between consumption patterns in a liberalizing versus a non-liberalizing country is directly related to the tariff reduction. Supply elasticities are identified by using tariffs as instruments for observed quantities. Analysis of world-wide trade data for 5,000 commodities shows that NAFTA and CUSFTA have had a substantial impact on international trade volumes, but a modest effect on prices and welfare. NAFTA and CUSFTA increased North American output and prices in many highly-protected sectors by driving out imports from non-member countries. ER -
