In this episode, Owen talks to fellow CGD Senior Fellow Michael Clemens about the relationship between migration and development.

Michael talks about the impact of migration on migrants themselves, and how micro-data has been used to expose a significant inequality of opportunity based on location. He then responds to various criticisms of migration from a receiving country perspective, focusing on the costs and benefits of the economic, communal and cultural effects of migration. At the end of the podcast, Michael discusses the impact of migration from the perspective of the migrants’ countries of origin. 

After the 2010 Haitian earthquake flattened Port-au-Prince, the United States responded with an outpouring of money, food, and medicine for Haiti. But a more effective form of assistance -- the powerful tool of migration and labor mobility -- was at first overlooked in relief and recovery efforts.

CGD senior fellow Michael Clemens led a two-year research and policy engagement effort that reached a milestone in January when the U.S. government added Haiti to the list of more than 50 countries eligible for temporary worker visas, the H-2 visa program.  Michael calculated at the time that if just 2,000 Haitians worked as H-2 workers in the United States each year (just 2% of total H-2s) over the course of 10 years they would earn $400 million in additional, new income for Haitian families—an amount equal to the entire U.S. post-earthquake budget for reconstruction in Haiti.

If you found a trillion-dollar bill on the sidewalk, would you pick it up? Michael Clemens thinks he has found a bunch of such bills—huge gains to the poor people and the world economy that could be achieved by easing restrictions on cross-border labor mobility.  He has written a working paper that sets forth a new research agenda on migration and is urging economists to pay more attention to the benefits of increased labor mobility for the people who move, the people and countries that receive them, and those who remain at home. In this week’s Wonkcast we discuss his four-point research agenda, and explore why some important questions about labor mobility are so rarely investigated.  

Take the topic of so-called “brain drain.” While plenty of research has gone into documenting the exodus of skilled workers from developing countries, Michael says, little research has examined the actual effects of these departures on those left behind—and even less has considered the welfare gains to those who move. “When people talk about migration at the international level, they tend to only focus on the costs,” says Michael. “This negative labeling happens to such a degree that they eventually define the movement with a pejorative little rhyme, brain drain.”

In development, it's good to try new, innovative ideas-- but even better to know whether or not they work. My guests this week are Michael Clemens, senior fellow at the Center for Global Development, and Gabriel Demombynes, a senior economist at the World Bank, based in Nairobi, Kenya. They have written a new paper in which they argue that one very high profile development program, the Millennium Villages Project, isn’t being evaluated in a way that would provide clear evidence of its impacts. They propose a better way to evaluate the project.
