We present a North-South model with labor market frictions and labor migration to study the dynamic implications of workers mobility on employment, capital accumulation and welfare. In the baseline model, the Northern country is able to control immigration flows by setting a cap on the number of foreign workers. We find that, despite an increase in migration displaces native employment in the short-run, a permanent raise of the migration cap stimulates capital accumulation, improves labor market conditions and increases social welfare in the long run. In an extension of the model, we also test the long-run effects of a pro-employment protectionist policy consisting in imposing a distortionary tax on immigrant employment. We find that the protectionist policy in North, while increasing national welfare, damages the macroeconomic performance of the domestic economy and is not effective in improving native employment.
