This paper studies the impact of U.S. immigration barriers on global knowledge production. We present four key findings. First, among Nobel Prize winners and Fields Medalists, migrants to the U.S. play a central role in the global knowledge network—representing 20-33% of the frontier knowledge...

For decades, migration economics has stressed the effects of migration restrictions on income distribution in the host country.

Economists recognize that nations can gain from trade through not only the free movement of goods across national boundaries but also the free movement of services, capital, and labor across national boundaries. Despite the presumption that economic theory raises in favor of international labor...

This paper estimates conditional demand models and, using a joint approach for the period 2008-2017, examines the impact of immigration and different measures of offshoring on the labour demand and demand elasticities of native workers in four different types of occupational groups:...

International migration of people is a momentous and complex phenomenon. Research on its causes and consequences, requires sufficient data. While some datasets are available, the nature of migration complicates their scientific use. Virtually no existing dataset captures international migration...

Over roughly the last ten years, there has been an explosion of scholarship on transnational labour law, as commentators attempt to come to terms with the shifting labour law paradigm in the new economy. Most of the work has filled law review pages. Fortunately, Sir Bob Hepple has led the way in...

We examine how variation in antisemitism across countries can be explained by economic freedom. We propose two mechanisms. First, the more economic freedom, the greater the scope of market activities. If people perceive the consequences of the market economy as detrimental, they will be more...

In this study we provide evidence that historical migration flows impact present-day global health differences. The underlying theory is based on three physiological facts. First, vitamin D deficiency is directly associated with increased risk of premature death. Second, the ability of humans to...
