Over the last decades, the United States has become increasingly integrated in the world economy. Very low trade barriers and comparatively liberal migration policies have made these developments possible. What drove US congressmen to support the recent wave of globalization? While much of the...

We study the migration policy set by a welfare maximizing government in a model where immigrant workers differ in their skills and are imperfectly matched with heterogenous occupations. The policy fixes a minimum skill level for legal migrants, and foreign workers that fall below it can only...

In 2008, approximately 12 million immigrants lived illegally in the United States, and large numbers of undocumented foreigners resided also in other advanced destination countries. Hence, attempts at controlling immigration flows seem to often fail. If governments are not enforcing their...

This chapter begins by documenting that temporary migrations are not only very common, but that outmigration of immigrants is selective both in terms of migrants’ individual characteristics and their economic outcomes. We then examine the problems that arise when estimating immigrants’...

There is strong public opposition to increased immigration throughout Europe. Given the modest economic impacts of immigration estimated in most studies, the depth of antiimmigrant sentiment is puzzling. Immigration, however, does not just affect wages and taxes. It also changes the composition...

This paper develops a model and derives novel testable implications of referral-based job search networks in which employees provide employers with information about potential job market candidates that they otherwise would not have. Using unique matched employeremployee data that cover the...

Sjaastad (1962) viewed migration in the same way as education: as an investment in the human agent. Migration and education are decisions that are indeed intertwined in many dimensions. Education and skill acquisition play an important role at many stages of an individual’s migration....

In this paper, we investigate how changes in the skill mix of local labor supply are absorbed by the economy. We distinguish between three adjustment mechanisms: through factor prices, through an expansion in the size of those production units that use the more abundant skill group more...

This paper starts with a brief historical overview of immigration in Europe. We then provide a comprehensive analysis of the skill structures of immigrants and their labor market integration in the different European countries, their position in the wage distribution, and the situation of their...

This paper investigates the educational achievements of second generation immigrants in several OECD countries in a comparative perspective. We first show that the educational achievement (measured as test scores in PISA achievement tests) of children of immigrants is quite heterogeneous across...
