Theoretical arguments and previous country-level evidence indicate that immigrants are more fluid than natives in responding to changing labor shortages across countries, skill-groups or industries. The diversity across EU member states enables us to test this hypothesis across various...

The H-1B program allows firms in the United States to temporarily hire high-skilled foreign citizens. H-1B workers are highly concentrated among a small number of firms. We develop a theoretical model demonstrating that this phenomenon is an artifact of policy design: When the government...

The paper provides an analysis of the recent immigration history of New Zealand and Australia. It starts with a description of the quantitative dimension of immigration: how many immigrants entered the two countries, and what was the contribution of external migration to population growth. Next,...

Canonical models of migration feature border enforcement as a strategy to contain undocumented immigration by effectively exacting a mobility cost. This paper revisits the role of border enforcement policy in a task-based model of the labor market where employers simultaneously hire circular...

The economic literature starting with Borjas (2001) suggests that immigrants are more flexible than natives in responding to changing sectoral, occupational, and spatial shortages in the labor market. In this paper, we study the relative responsiveness to labor shortages by immigrants from...

In this paper, I estimate the fiscal impact of immigrants on the German pension insurance (PI) and unemployment insurance (UI) systems when return migration is an endogenous choice. For this purpose, I develop a dynamic stochastic model of joint return migration and saving decisions that...

We review developments in research on within-country migration, focusing on internal migration in the U.S. We begin by describing approaches to modelling individuals' migration decisions and equilibrium outcomes across local areas. Next, we summarize evidence regarding the impact of migration on...

The 1986 US Immigration Reform and Control Act (IRCA) was directed at tackling the problem of growing unauthorized migration through legalization of unauthorized immigrants, increasing border security and sanctioning employers who hired unauthorized immigrants. Our paper investigates how the...

Attracting skilled immigrants is emerging as an important policy goal for immigrant receiving countries. This article first discusses the economic rationale for immigrant selection. Selection mechanisms of receiving countries are reviewed in the context of deteriorating labor market outcomes for...

Poland has traditionally been treated as an emigration country. Since recently Poland has been changing into an emigration-immigration country. The latter, namely immigration, was boosted by the European Union membership and by stable and strong growth of the country. In the last years,...
