On February 5, 1917, the United States passed the Immigration Act of 1917, which included a test for all migrants arriving to the U.S. to prove they were literate. The Literacy Test was one of the first and few times the U.S. used a broad 'skill-based' immigration policy in an attempt to limit...

Why were the poorer countries of the European periphery latecomers to the Age of Mass Migration? We test the diffusion hypothesis, which argues that mass emigration was delayed because it was primarily governed by a gradual process of spatial diffusion of migration networks. We propose a model...

We estimate spillovers from public funding for health research in the context of the NIH's Fogarty International Center's AIDS International Training and Research Program, which aims to strengthen scientific capacity in AIDS endemic countries by providing African researchers with training...

Seit dem Jahr 2017 wird im Mikrozensus erfasst, welche Motive im Ausland geborene Personen für ihren Zuzug hatten. Daraus lassen sich neue Erkenntnisse darüber gewinnen, in welchen Kontexten die Zuwanderung nach Deutschland erfolgt. So zeigt eine eigene Auswertung, dass im Jahr 2017 rund 1,06...

This essay provides a broad and in-depth account of the effects of the post-enlargement migration flows on the receiving as well as sending countries in three broader areas: labour...

This paper is based on recently collected and rich survey data of a representative sample of entrants into unemployment in Germany. Our data include a large number of migration variables, allowing us to adapt a recently developed concept of ethnic identity: the ethnosizer. To shed further light...

Economic reasons along with cultural affinities and the existence of networks have been the main determinants explaining migration flows between home and host countries. This paper reconsiders these approaches combined with the gravity model and empirically tests the hypothesis that ex-colonial...

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...

Das ökonomische Potenzial ethnischer und kultureller Vielfalt wird häufig verkannt. Die Ergebnisse neuerer Studien, die in diesem Beitrag zusammengefasst werden, zeigen jedoch, dass sich "weiche" Faktoren wie etwa Einstellungen, Wahrnehmungen und Identitäten, hier insbesondere ethnische...

This paper empirically analyzes the relationship between migration and human trafficking inflows into Germany during the period between 2001 and 2010. My results suggest that migrant networks, measured by migrant stocks from a specific source country, have a causal linkage with the illicit,...
