Migration and the Trillion Dollar Bills on the Sidewalk: Michael Clemens

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.”
U.S. Disaster Assistance and Migration Policy: Michael Clemens

When a catastrophic earthquake struck Haiti last year the U.S. government and public moved quickly to aid the survivors. The response was swift and compassionate. But America did not do something simple and low-cost that could have helped the survivors of this horrible event. It did not crack open the door and admit a small number of them to the United States.
On this week’s Wonkcast, I’m joined by senior fellow Michael Clemens to discuss why US immigration policy should be part of the United States’ official humanitarian response to natural disasters. Michael, who leads CGD’s work on migration and development, recently commissioned a working paper to figure out what if anything can be done to open a channel for limited numbers of disaster refugees to enter the United States.
Paul Romer’s Bold New Idea for Charter Cities
The planet's population will swell by two to three billion people over the next few decades. Where will all those people live? My guest on this week's Global Prosperity Wonkcast has a bold new idea. Paul Romer is a senior fellow at the Stanford Institute for Economic Policy Research, a non-resident fellow here at the Center for Global Development, and one of the world’s leading growth economists. He is proposing brand new cities—he calls them ‘charter cities’—built from the ground up with sound rules designed to promote swift development.
The two ideas at the heart of Paul's proposal are, first, that good rules are fundamental to development and, second, that new cities might be able to draw their rules, people, and land from different sources. He argues that inadequate property rights, legal systems, and other types of rules hold back development in poor countries. If the residents of a poor country could choose to live in a new city, governed by the rules of a well-functioning country, they might benefit enormously. If good rules are in place, Paul says, where that city is located doesn’t matter much.
Last week, a bipartisan g
