Are your wages determined by what you know, or where you are? This paper estimates how the wages of workers in 42 developing countries would change if the same people could work in the United States. It uses a rich new database on over two million workers around the world. A worker from the median country would earn about 2.7 times as much in the US as at home. This means that (1) for many countries, the wage gaps caused by barriers to movement across international borders are among the largest known forms of wage discrimination; (2) these gaps represent one of the largest remaining price distortions in any global market; and (3) simply allowing labor mobility can reduce a given household’s poverty to a much greater degree than most known antipoverty interventions inside developing countries.
International migration has long been a central tool in the battle against global poverty and inequality, but the recent heated political debate over immigration reform has largely failed to recognize how migration shapes the development process. In this essay, research fellow Michael Clemens and co-author Sami Bazzi outline five major reasons why migration is a development issue in today’s world, and they suggest an agenda for the next U.S. administration to make U.S. migration policy work for the United States, for countries of origin, and for the migrants themselves.
