The paper empirically explores the international economic effects of gender discrimination, namely the linkages of gender inequality with comparative advantage (trade) and foreign direct investment flows. It discusses different forms and the extent of gender discrimination across countries and presents the results of empirical tests of those linkages. The results indicate that gender inequality is positively associated with comparative advantage in unskilled-labour-intensive goods, that is, commodities where the impact of gender bias is likely to be felt most strongly. In contrast, foreign direct investment is negatively linked with gender inequality. These results even hold for relatively poor developing countries.
