Abstract:In this paper, we examine the effects of liberalization on industrial location and national welfare in a framework of new economic geography. Specifically, we explicitly incorporate arbitrary trade costs in both differentiated-good and homogeneous-good sectors into a two-country model, and clarify the effects of trade-barrier reduction in each sector. We show that their impacts on welfare levels in the two countries are different, and, if an industry is liberalized while the other is protected, a conflict between the countries might occur. Therefore, appropriate liberalization in both sectors is effective to alleviate such a conflict.
