討論提要

This paper develops a model with heterogeneous firms to analyze the intra-industry effects of international trade. The model shows how the exposure to trade will induce only the more productive firms to enter the export market and will simultaneously force the least productive firms to exit. It then shows how further increases in the industry’s exposure to trade lead to additional inter-firm reallocations towards more productive firm. The paper also shows how the aggregate industry productivity growth generated by the reallocations contributes to a welfare gain, thus highlighting a benefit from trade that has not been examined theoretically before.
