  • STAY OR LEAVE? CHOICE OF PLANT LOCATION WITH COST HETEROGENEITY Reviewed

    Using a two-country model, we examine location choices by two domestic firms when they serve only the domestic market and their cost structures differ. The findings indicate that whether the firm that has a greater incentive for foreign direct investment is more or less efficient depends on the differences in domestic and foreign marginal costs, trade costs, and the presence of fixed costs. Plant locations may not be uniquely determined. In particular, a small change in trade costs may reverse plant location. Moreover, a decrease in transport costs in the presence of foreign direct investment may deteriorate domestic welfare.

    This paper explores the effects of transport costs, tariffs, and foreign wage rates on the domestic economy in the presence of reverse imports, with special emphasis on inter-firm cost asymmetry in an international oligopoly model. To serve the domestic market, a foreign firm produces in the foreign country, while two domestic firms produce either at home or abroad. Surprisingly, an increase in the foreign wage rate may increase the profits of a firm producing in the foreign country. Even if all firms produce in the foreign country, an increase in the foreign wage rate may improve domestic welfare.

    In this research project, we reexamined the effects of trade policies, such as regional trade agreements and transfer pricing taxation, which have become more important in recent years. In particular, we reassessed the effects of trade policy, taking into account corporate behavior that affects demand such as product differentiation, intra-industry trade that has been increasing in recent years, and the existence of technology licenses. The results have shown that firms' product differentiation and transfer pricing change the impact of various trade policies.

    It is theoretically shown that both countries participating in a bilateral regional trade agreement can improve economic welfare by including an agreement on movement of natural person. By solving a policy-making game by the governments of the two countries, it also theoretically showed the possibility that trade liberalization and investment liberalization can be substantially realized at the same time. These results must be an academic support in deciding to which level of liberalization and/or cooperation should be included in Japan’s economic partnership agreements.
    Empirical analysis could not be finished. However, I came to the conclusion that it is possible to empirically analyze the impact of movement of natural person on trade and foreign direct investment by focusing on APEC Business Travel Card and/or US H-1B visa.
