Abstract:
We compare the wages of workers inside the United States to the wages of observably identical workers outside the United States—controlling for country of birth, country of education, years of education, work experience, sex, and rural-urban residence. This is made possible by new and uniquely rich microdata on the wages of over two million individual formal-sector wage-earners in 43 countries. We then use five independent methods to correct these estimates for unobserved differences between the productivity of migrants and non-migrants, as well as for the wage effects of natural barriers to international movement in the absence of policy barriers. We also introduce a selection model to estimate how migrants' wage gains depend on their position in the distribution of unobserved wage determinants both at the origin and at the destination, as well as the relationship between these positions. For example, in the median wage gap country, a typical Bolivian-born, Bolivian-educated, prime-age urban male formal-sector wage worker with moderate schooling makes 4 times as much in the US as in Bolivia. Following all adjustments for selectivity and compensating differentials we estimate that the wages of a Bolivian worker of equal intrinsic productivity, willing to move, would be higher by a factor of 2.7 solely by working in the United States. While this is the median, this ratio is as high as 8.4 (for Nigeria). We document 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) these gaps imply that imply allowing labor mobility can reduce a given household's poverty to a much greater degree than most known in situ antipoverty interventions.

Abstract:
Does the emigration of highly-skilled workers deplete local human capital? The answer is not obvious if migration prospects induce human capital formation. We analyze a unique natural quasi-experiment in the Republic of the Fiji Islands, where political shocks have provoked one of the largest recorded exoduses of skilled workers from a developing country. Mass emigration began unexpectedly and has occurred only in a well-defined subset of the population, creating a treatment group that foresaw likely emigration and two different quasi-control groups that did not. We use rich census and administrative micro data to address a range of concerns about experimental validity. This allows plausible causal attribution of post-shock changes in human capital accumulation to changes in emigration patterns. We show that high rates of emigration by tertiary-educated Fiji Islanders not only raised investment in tertiary education in Fiji; they moreover raised the stock of tertiary educated people in Fiji—net of departures.

23. Do Visas Kill? Health Effects of African Health Professional Emigration

Abstract:
The emigration of highly skilled workers can in theory lower social welfare in the migrant-sending country. If such workers produce a good whose consumption conveys a positive externality—such as nurses and doctors in a very poor country—the loss can be greater, and welfare can even decline globally. Policies to impede emigration thus have the potential to raise sending-country and global welfare. This study uses a new database of health worker emigration from Africa to test whether exogenous decreases in emigration raise the number of domestic health professionals, increase the mass availability of basic primary care, or improve a range of public health outcomes. It identifies the effect through two separate natural quasi-experiments arising from the colonial division of the African continent. These produce exogenous changes in emigration comparable to those that would result from different immigration policies in principal receiving countries. The results suggest that Africa's generally low staffing levels and poor public health conditions are the result of factors entirely unrelated to international movements of health professionals. A simple model proposes that such results would be explained by segmentation of health workforce labor markets in the sending countries. The results further suggest that emigration has caused a greater production of health workers in Africa.
