Regional Trade Integration and Multinational Firm Strategies

Abstract

This paper analyzes the e¤ects of the formation of a regional trade agreement on the level and nature of multinational …rm activity. We examine aggregate data that captures the response of U.S. multinational …rms to the formation of the ASEAN free trade agreement. Observed patterns guide the development of a model in which heterogeneous …rms from a source country decide how to serve two foreign markets. Following a reduction in tari¤s on trade between the two foreign countries, the model predicts growth in the number of source-country …rms engaging in foreign direct investment, growth in the size of a¢ liates that are active in reforming countries both before and after the tari¤ reduction, and an increase in the extent to which the sales of a¢ liates in reforming countries are directed towards other reforming countries. Analysis of …rm-level responses to the creation of the ASEAN free trade agreement yields results that are consistent with these predictions.
