Migration and development, economic growth, aid effectiveness, economic history
Michael Clemens is director of migration, displacement, and humanitarian policy and a senior fellow at the Center for Global Development, where he studies the economic effects and causes of migration around the world. He has published on migration, development, economic history, and impact evaluation, in peer-reviewed academic journals including the American Economic Review, and his research has been awarded the Royal Economic Society Prize. He also serves as a Research Fellow at the IZA Institute of Labor Economics in Bonn, Germany, and has served as an Associate Editor of the Journal of Population Economics and World Development. He is the author of the book The Walls of Nations, forthcoming from Columbia University Press. Previously, Clemens has been an Affiliated Associate Professor of Public Policy at Georgetown University, a visiting scholar at New York University, and a consultant for the World Bank, Bain & Co., the Environmental Defense Fund, and the United Nations Development Program. He has lived and worked in Colombia, Brazil, and Turkey. He received his PhD from the Department of Economics at Harvard University, specializing in economic development, public finance, and economic history.
The arrival of more than a million refugees and migrants in Europe has brought widespread concern they will become an economic drain on the countries that welcome them. When economists have studied past influxes of refugees and migrants they have found the labor market effects, while varied, are very limited, and can in fact be positive.
Do immigrants from poor countries hurt native workers? A study by an influential immigration economist at Harvard University recently found that a famous flood of Cuban immigrants into Miami dramatically reduced the wages of native workers. But there’s a problem. The Borjas study had a critical flaw that makes the finding spurious.
When opportunities for corrupt earnings rise, is there more corruption? This fundamental question is the subject of new, frontier-pushing research by two young stars of development economics: CGD alumnus Sandip Sukhtankar and his co-author Paul Niehaus.
For decades, migration economics has stressed the effects of migration restrictions on income distribution in the host country. Recently the literature has taken a new direction by estimating the costs of migration restrictions to global economic efficiency. In contrast, a new strand of research posits that migration restrictions could be not only desirably redistributive, but in fact globally efficient. This is the new economic case for migration restrictions: empirically, a case against the stringency of current restrictions.
Using data collected by the North Carolina Growers’ Association (NCGA), the leading employer of workers with H-2 visas, Michael Clemens shows that foreign workers have almost no direct effect on the employment prospects of US workers in H-2 occupations. Instead, they actually a large and positive indirect effect on US employment by contributing to North Carolina’s economy.
It was a big deal when various media outlets declared last week that the evidence to support mass deworming had been “debunked.” The debate now is not about whether children sick with worms should get treated (everyone says yes), but whether the mass treatment of all kids — including those not known to be infected — is a cost-effective way to raise school attendance. The healthiest parts of the debate have been about the need for transparency, data sharing, and more replication in science. Here, we’re going to focus here on the narrower question of the evidence for mass deworming specifically, which is where some journalists have gotten things quite wrong.
‘Guest workers’ earn higher wages overseas on temporary low-skill employment visas. This wage gap can be used to measure gaps in the productivity of workers due to where they are, not who they are. This paper estimates the effects of guest work on Indian applicants to a construction job in the United Arab Emirates, where an economic crisis allocated guest work opportunities as-good-as-randomly among several thousand families. Guest work raised the return to poor families' labor by a factor of four, with little evidence of systematic fraud.
There are over 25 million refugees in the world today and most of them—especially those in developing countries—do not have formal labor market access (LMA). Granting refugees formal LMA has the potential to create substantial benefits for refugees and their hosts.
Workers from poor countries can find enormous economic opportunity by working temporarily in a rich country. But agencies that fight global poverty do little to facilitate guest work. This may be because guest workers are perceived to typically suffer negative side effects that outweigh the benefits. This paper uses a natural experiment to test several perceptions of harmful side-effects on Indian guest workers in the Gulf. The research shows little evidence that the harmful side-effects often ascribed to guest work are typical and systematic, though this does not contradict the occurrence of many individual cases of harmful side-effects.
This paper studies the relationship between violence in the Northern Triangle and child migration to the United States. It finds that one additional homicide per year in the region, sustained over the six-year period of study—that is, a cumulative total of six additional homicides—caused a cumulative total of 3.7 additional unaccompanied child apprehensions in the United States. The explanatory power of short-term increases in violence is roughly equal to the explanatory power of long-term economic characteristics like average income and poverty.
An influential strand of research has tested for the effects of immigration on natives’ wages and employment using exogenous refugee supply shocks as natural experiments. Several studies have reached conflicting conclusions about the effects of noted refugee waves such as the Mariel Boatlift in Miami and post-Soviet refugees to Israel. As a whole, the evidence from refugee waves reinforces the existing consensus that the impact of immigration on average native-born workers is small, and fails to substantiate claims of large detrimental impacts on workers with less than high school.
