| Summary: | Adapting our earlier model of multinationals, we address policy issues involving wages and labor skills. Multinational firms may arise endogenously, exporting their firm-specific knowledge capital to foreign production facilities, and geographically fragmenting production into skilled and unskilled-labor-intensive activities. Multinationals thus alter the nature of trade, from trade in goods (produced with both skilled and unskilled labor) to trade in skilled-labor-intensive producer services. Results shed light on several policy questions. First, multinationals increase the skilled/unskilled wage gap in the high income country and, under some circumstances, in the low income country as well. Second, there is a sense in which multinationals export low skilled jobs to the lower income country. Third, trade barriers do not protect unskilled labor in the high income countries. By inducing a regime shift to multinationals, trade barriers protect the abundant factor, at least in the high income country and possibly in both countries. Fourth, a convergence in country characteristics induces the entry of multinationals and raises the skilled-unskilled wage gap in the initially large and skilled-labor-abundant country, and possibly in the small skilled-labor-scarce country as well.
