We show that the Roy model has more precise predictions about the self-selection of migrants than previously realized. The same conditions that have been shown to result in positive or negative selection in terms of expected earnings also imply a stochastic dominance relationship between the...

About 1.4 million refugees and irregular migrants arrived in Europe in 2015 and 2016. We model how refugees and irregular migrants are self-selected. Using unique datasets from the International Organization for Migration and Gallup World Polls, we provide the first large-scale evidence on...

Integration of immigrants is a two-way process, the success of which depends both on immigrants and on natives. We provide new evidence on the determinants of individual attitudes towards immigration, using data from the 2005 and 2010 waves of the German Socio-Economic Panel. In particular, we...

We study the effects of immigration on native welfare in a general equilibrium model featuring two skill types, search frictions, wage bargaining, and a redistributive welfare state. Our quantitative analysis suggests that, in all 20 countries studied, immigration attenuates the effects of...

Immigration has become one of the most divisive political issues in the United States, the United Kingdom, France and several other Western countries. We estimate the impact of immigration on voting for far-left and far-right candidates in France, using panel data on presidential elections from...

We analyze self-selection and sorting of emigrants from Finland, using full-population administrative data from Statistics Finland. We analyze emigration events lasting at least five years and decompose migrant self-selection into education, occupation, and unobserved abilities. Our analysis...

Immigration is one of the most divisive political issues in many countries today. Competing narratives, circulated via the media, are crucial in shaping how immigrants' role in society is perceived. We propose a new method combining advanced natural language processing tools with dictionaries to...

We examine how cultural norms shape attitudes toward immigration. Our causal identification relies on comparing students who moved across the East-West border after German reunification with students who moved within former East Germany. Students who moved from East to West became more positive...

Manufacturing accounts for more than three-quarters of U.S. corporate patents. The competitive shock to this sector emanating from China's economic ascent could in theory either augment or stifle U.S. innovation. Using three decades of U.S. patents matched to corporate owners, we quantify how...

It has been argued that in the absence of altruism, intergenerational transfers can survive only if the old are net recipients. I prove that this need not hold in an over-lapping generations model with a fixed factor. For example, the middle-aged owning land may gain by providing public...
