Talent is the most precious resource for today's knowledge-based economy, and a significant share of the U.S. skilled workforce in technology fields is foreign born. The United States has long held a leading position in attracting global talent, but the gap to other countries is weakening....

Migration outflows, especially of young people, may deprive an economy of entrepreneurial energy and innovative ideas. We exploit exogenous variation in emigration from Italian local labor markets to show that between 2008 and 2015 larger emigration flows reduced firm creation. The decline...

Migration and pollution are two defining features of China's impressive growth performance over the last 30 years. In this paper we study the migration response to pollution in Chinese cities, and its consequences for productivity and welfare. We document a robust pattern in which skilled...

We introduce international mobility of knowledge workers into a model of Nash equilibrium IPR policy choice among countries. We show that governments have incentives to use IPRs in a bidding war for global talent, resulting in Nash equilibrium IPRs that can be too high, rather than too low, from...

The development prospects of a poor country depend in part on its capacity for innovation. The productivity of its innovators depends in turn on their access to technological knowledge. The emigration of highly skilled individuals weakens local knowledge networks (brain drain), but may also help...

Recent theoretical and empirical studies have emphasized the fact that the prospect of international migration increases the expected returns to skills in poor countries, linking the possibility of migrating (brain drain) with incentives to higher education (brain gain). If emigration is...

We consider the welfare effects of the emigration of workers who produce a public good (knowledge). We distinguish between the knowledge diversion and knowledge creation effects of such emigration, and show that the remaining residents of a country can gain from emigration, even when tastes for...

In the first global century before 1914, trade and especially migration had profound effects on both low-wage, labor abundant Europe and the high-wage, labor scarce New World. Those global forces contributed to a reduction in unskilled labor scarcity in the New World and to a rise in unskilled...
