Skill Flow: A Fundamental Reconsideration of Skilled-Worker Mobility and Development

Large numbers of doctors, engineers, and other skilled workers from developing countries choose to move to other countries. Do their choices threaten development? The answer appears so obvious that their movement is most commonly known by the pejorative term “brain drain.” This paper reconsiders the question, starting from the most mainstream, explicit definitions of “development.” Under these definitions, it is only possible to advance development by regulating skilled workers’ choices if that regulation greatly expands the substantive freedoms of others to meet their basic needs and live the lives they wish. Much existing evidence and some new evidence suggests that regulating skilled-worker mobility itself does little to address the underlying causes of skilled migrants’ choices, generally brings few benefits to others, and often brings diverse unintended harm. The paper concludes with examples of effective ways that developing countries can build a skill base for development without regulating human movement. The mental shift required to take these policies seriously would be aided by dropping the sententious term “brain drain” in favor of the neutral, accurate, and concise term “skill flow.”brain drain; migration; development; labor; education; developing; labor mobility; circular migration; higher education; university; training; skilled; high skill; talent; globalization; health workers; high tech; technology transfer

Do Visas Kill? Health Effects of African Health Professional Emigration

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.emigration, health professionals, visas, africa, highly skilled workers, public health

A Labor Mobility Agenda for Development

Rich countries have made efforts for half a century to help people in poor countries catch up to rich-country standards of living. Those efforts have included giving foreign aid, encouraging overseas investment, dismantling trade barriers, and spreading ideas and institutions. That is, their international development policy has been to encourage the globalization of almost all factors of production—except labor. So far, this policy has failed to cause the living standards of most people in most developing countries to converge with living standards in rich countries. But the globalization of labor—greater mobility for workers across borders—quickly and massively raises migrants’ living standards toward those of rich countries. This paper argues that every rich country should consider its immigration policy to be part of its international development policy, and vice versa. A development policy that includes migration will be more effective; an immigration policy that includes development will better serve rich countries’ ideals and interests. The paper also gives a non-technical review of new research on several common objections to unifying development policy and migration policy. One concrete way forward is for rich countries to greatly open up legal pathways for temporary labor movement.international development; immigration policy; labor; migration

Time-Bound Labor Access to the United States: A Four-Way Win for the Middle Class, Low-Skill Workers, Border Security, and Migrants

The US economy needs low-skill workers now more than ever, and that requires a legal channel for the large-scale, employment-based entry of low-skill workers. The alternative is what the country has now: a giant black market in unauthorized labor that hinders job creation and harms border security. A legal time-bound labor-access program could benefit the American middle class and low-skill workers, improve US border security, and create opportunities for foreign workers

Ghost of 0.7%: Origins and Relevance of the International Aid Target

The international goal for rich countries to devote 0.7% of their national income to development assistance has become a cause célèbre for aid activists and has been accepted in many official quarters as the legitimate target for aid budgets. The origins of the target, however, raise serious questions about its relevance. First, the 0.7% target was calculated using a series of assumptions that are no longer true, and justified by a model that is no longer considered credible. When we use essentially the same method used to arrive at 0.7% in the early 1960s and apply today’s conditions, it yields an aid goal of just 0.01% of rich-country GDP for the poorest countries and negative aid flows to the developing world as a whole. We do not claim in any way that this is the 'right' amount of aid, but only that this exercise lays bare the folly of the initial method and the subsequent unreflective commitment to the 0.7% aid goal. Second, we document the fact that, despite frequent misinterpretation of UN documents, no government ever agreed in a UN forum to actually reach 0.7%—though many pledged to move toward it. Third, we argue that aid as a fraction of rich country income does not constitute a meaningful metric for the adequacy of aid flows. It would be far better to estimate aid needs by starting on the recipient side with a meaningful model of how aid affects development. Although aid certainly has positive impacts in many circumstances, our quantitative understanding of this relationship is too poor to accurately conduct such a tally. The 0.7% target began life as a lobbying tool, and stretching it to become a functional target for real aid budgets across all donors is to exalt it beyond reason. That no longer makes any sense, if it ever did.aid, foreign aid, development, mdg, mdgs, millennium development goals, oda, united nations, un, overseas development assistance, africa

Skilled Emigration and Skill Creation: A quasi-experiment

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 microdata 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.migration, human capital, fiji

A Lack of Resolved Near-Infrared Polarization Across the Face of M51

The galaxy M51 was observed using the Mimir instrument on the Perkins telescope to constrain the resolved H-band (1.6 $\mu$m) polarization across the galaxy. These observations place an upper limit of $P_H<0.05$ on the $H$-band polarization across the face of M51, at 0.6 arcsecond pixel sampling. Even with smoothing to coarser angular resolutions, to reduce polarization uncertainty, the $H$-band polarization remains undetected. The polarization upper limit at $H$-band, when combined with previous resolved optical polarimetry, rules out a Serkowski-like polarization dependence on wavelength. Other polarization mechanisms cannot account for the observed polarization ratio ($P_H/P{VRI} \lesssim 0.05$) across the face of M51.Comment: 4 pages, 2 figures, Accepted for publication in ApJ

H II Region Driven Galactic Bubbles And Their Relationship To The Galactic Magnetic Field

The relative alignments of mid-infrared traced Galactic bubbles are compared to the orientation of the mean Galactic magnetic field in the disk. The orientations of bubbles in the northern Galactic plane were measured and are consistent with random orientations-no preferential alignment with respect to the Galactic disk was found. A subsample of H II region driven Galactic bubbles was identified, and as a single population they show random orientations. When this subsample was further divided into subthermal and suprathermal H II regions, based on hydrogen radio recombination linewidths, the subthermal H II regions showed a marginal deviation from random orientations, but the suprathermal H II regions showed significant alignment with the Galactic plane. The mean orientation of the Galactic disk magnetic field was characterized using new near-infrared starlight polarimetry and the suprathermal H II regions were found to preferentially align with the disk magnetic field. If suprathermal linewidths are associated with younger H II regions, then the evolution of young H II regions is significantly affected by the Galactic magnetic field. As H II regions age, they cease to be strongly linked to the Galactic magnetic field, as surrounding density variations come to dominate their morphological evolution. From the new observations, the ratios of magnetic-to-ram pressures in the expanding ionization fronts were estimated for younger H II regions.NSF AST 06-07500, 09-07790NASAW. M.
