AbstractIncrease in trade has an asymmetric impact on emigration by skill types for a developing country. Cost of migration is a dynamic function of the type of emigration, and it determines a complementary relation between emigration of skilled workers and expansion of trade. Emigration of unskilled workers is a substitute, however, and these outcomes coexist with endogenously determined emigration rates that depend crucially on wage responses among the own skill types at the source. Additionally, asymmetric emigration patterns increase wage inequality.
