Tariff Liberalization and Trade Integration of Emerging Countries

This paper investigates how tariff liberalization has affected exporting in emerging countries. We use a highly disaggregated (6 digit level of the harmonized system – HS – classification) bilateral measure of market access to compare tariffs applied in 1996 and 2006, which includes the timing of the Uruguay Round and episodes of bilateral liberalization. Our econometric estimations consider impacts on both the extensive and intensive margins of trade. The reduced tariffs imposed on emerging countries have contributed to growth in their exports of differentiated goods at the intensive margin; they have not affected the probability of recording new flows. Growth in emerging countries’ exports at the extensive margin of trade has been due mainly to an upward shift in their comparative advantage and improvements to their infrastructure.
