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...

We estimate the impact of the income earned in the host country on return migration of labor migrants from developing countries. We use a three-state correlated competing risks model to account for the strong dependence of labor market status and the income earned. Our analysis is based on...

Migration has manifested itself to historic highs, creating divisive views among politicians, policy makers, and individuals. The present paper studies the Europeans' attitudes toward immigration, focusing particularly on the role of social capital. Based on 267,282 respondents from 22 countries...

Using census data for 1996, 2001 and 2007 we study the labor market effect of immigration to South Africa. The paper contributes to a small but growing literature on the impact of South-South migration by looking at one of the most attractive destinations for migrant workers in Sub-Saharan...

We estimate differences in innovation behavior between foreign versus U.S.-born entrepreneurs in high-tech industries. Our data come from the Annual Survey of Entrepreneurs, a random sample of firms with detailed information on owner characteristics and innovation activities. We find uniformly...

I examine the effect of immigrant inflows in Europe on natives' individual attitudes towards redistribution and immigration policy over the last decade. Unlike previous studies, I analyze the evolution over time of these two types of attitudes in a joint empirical framework. Using migration data...

This paper examines the causality relationship between immigration, unemployment and economic growth of the host country. We employ the bootstrap panel Granger causality testing approach of Kónya (2006) that allows to test for causality on each individual country separably by accounting for...

Using a dataset of science and engineering graduates from 12 European countries, we analyse the determinants of labour migration after graduation. We find that not only wage gains are driving the migration decision, but also differences in labour market opportunities, past migration experience,...

The U.S. limits work visas for low-skill jobs outside of agriculture, with a binding quota that firms access via a randomized lottery. We evaluate the marginal impact of the quota on firms entering the 2021 H-2B visa lottery using a novel survey and pre-analysis plan. Firms exogenously...

Whether Europe will be able to stand up to its internal and external challenges crucially depends on its ability to manage its internal mobility and inflows of international migrants. Using a unique expert opinion survey, we document that Europe needs skilled migrants, and skill mismatch is to...
