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,...

International migration is maybe the single most effective way to alleviate global poverty. When a given host country allows more immigrants in, this creates costs and benefits for that particular country as well as a positive externality for individuals and governments who care about world...

We provide an overview of the integration of refugees into the labor markets of a number of high-income countries. Discussing the ways in which refugees and economic migrants are differently selected and so might be expected to perform differently in a host country's labor market, we examine...

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...

Denmark has accepted refugees from a large variety of countries and for more than four decades. Denmark has also frequently changed policies and regulations concerning integration programs, transfer payments, and conditions for permanent residency. Such policy variation in conjunction with...

Did recent technological change, in the form of automation, affect immigration policy in the United States? I argue that as automation shifted employment from routine to manual occupations at the bottom end of the skill distribution, it increased competition between natives and immigrants,...

We study the extent to which migrant inflows to the United States affect the political polarization of campaign donors and the ideology of politicians campaigning for the House of Representatives in the 1992-2016 period. Implementing various polarization measures based on ideology data derived...

Low-skilled immigrants indirectly affect public finances through their effect on native wages & labor supply. We operationalize this general-equilibrium effect in the workhorse labor market model with heterogeneous workers and intensive and extensive labor supply margins. We derive a closed-form...

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...
