There is abundant evidence that immigrant networks are associated with larger exports from the country where they settle to their countries of origin. The direction of causality of this association is less clearly established. Also, we do not know to what extent these increased exports are due...

Though globalisation of the world economy is currently a powerful force, people’s international mobility appears to still be very limited. The goal of this book is to improve our knowledge of the true effects of migration flows. It includes contributions by prominent academic researchers...

In this paper, we estimate the effect of increasing the share of foreign-born Master graduates on the creation of innovative start-ups in the US. We combine information on international students graduating from Master's programs by university cohort with data on start-ups created in the US...

Children of refugees are among the most economically disadvantaged youth in several European countries. They are more likely to drop out of school and to commit crime. We show that a reform in Denmark in 1999, that expanded language training for adult refugees and improved their economic...

US universities have attracted hundreds of thousands of international students each year for the last decade. Some of these remain in the US after graduating and contribute to the high skilled labor supply in US labor markets. In this paper, we identify and estimate by how much one more...

In this study, we first evaluate the effect of a significant increase in low-skilled immigration in Korean municipalities from 2010-2015 on the internal migration of natives.

We analyze whether second-generation immigrants have different political preferences relative to observationally identical children of citizens in the host countries. Using data on individual voting behavior in 22 European countries between 2001 and 2017, we characterize each vote on a...

From the beginning of the Covid-19 pandemic to late 2021, international immigration flows to the US decreased significantly. We document the timing and the characteristics of these significant changes in flows, their evolution until late 2022 and their geographic and sector distribution. We...

This paper estimates, within a common framework, the effects of four types of integration polices on the employment probability and earnings of refugees in Denmark during the last three decades. We first review the studies that use a credible identification strategy to evaluate the causal...
