Immigration policies in western democracies have often been contrary to the policies predicted by the mainstream theory of international economics. In particular, political parties that, according to economic theory, should adopt policies beneficial for lower-income voter-constituencies, have...

This article studies the impact of immigration restriction policies on technology adoption in sending countries. From 1920 to 1921, the number of Italian immigrants to the United States dropped by 85% after Congress passed the Emergency Quota Act, a severely restrictive immigration law. In a...

Using data from two representative and large-scale population surveys with more than 4000 participants, we investigate the effect of randomized priming interventions on attitudes towards immigrants. We document robust null effects of these interventions under two experimental settings, across...

Does the emigration of skilled individuals necessarily result in losses for source countries due to the brain drain? Combining industry-level patenting and migration data from 32 European countries, we show that emigration in fact positively contributes to innovation in source countries. We use...

This paper sheds light on the apparent paradox, wherein populations adversely affected by climatic conditions fail to migrate as much as would otherwise be expected. Drawing on Hirschman's treatise on Exit, Voice and Loyalty, we develop a simple model, which highlights the theoretical case for a...

Are natural resources a 'curse' or a 'blessing'? The empirical evidence suggests either outcome is possible. The paper surveys a variety of hypotheses and supporting evidence for why some countries benefit and others lose from the presence of natural resources. These include that a resource...

Existing migrant networks play an important role in explaining the size and structure of immigration flows. They affect the net benefits of migration for future migrants by lowering assimilation costs ('self-selection' channel) and increase the probability of potential migrants to obtain a visa...

We study immigration policy in a small receiving economy under self-selection of migrants. We show that a non-discriminatory immigration policy choice affects and is affected by the migratory decisions of skilled and unskilled foreign workers. From this interaction multiple equilibria may arise,...
