Diasporas are global communities of migrants who retain a sense of connection with their homeland. The concept is ancient but has only recently become an important area of research in economics. Due to their unique transnational characteristics, diasporas can have significant influence over...

Canada's immigration system is currently undergoing significant change driven by several goals that include (1) a desire to improve the economic outcomes of entering immigrants; (2) an attempt to better respond to short-term regional labor market shortages often associated with commodity booms,...

In 2007, the State of Arizona passed the Legal Arizona Workers Act (LAWA) which required all employers to verify the legal status of all prospective employees. Replicating existing results from the literature, we show that LAWA displaced about 40,000 Mexican-born people from Arizona. About 25%...

The European Union aims at a stronger participation by its population in work to foster growth and welfare. There are concerns about the attachment of immigrants to the labour force, and discussions about the necessary policy responses. Integrated labour and migration policies are needed. The...

Based on the current European discussion about immigration policy, this paper gives an overview of central economic consequences of immigration for a host country's labor market. The most important theoretical arguments are presented and evaluated against the available empirical evidence. The...

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 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...

This paper presents a methodology to identify net demand shocks as well as wage rigidities in heterogeneous labor markets on the basis of nonparametric regression. We show how this approach can be used to make suggestions for immigration policy in economies with labor market rigidities. In an...

Among all European countries, Germany absorbs by far the largest number of immigrants. But to date, the German government has yet to adopt a system that will effectively control the influx of foreigners. The immigration of Ethnic Germans from Eastern Europe, which is due to historical events and...

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...
