Academia and the public media have emphasized the link between STEM majors and innovation, as well as the need for STEM graduates in the U.S. economy. Given the proclivity of international students to hold STEM degrees, immigration policy may be used to attract and retain high-skilled STEM...

The eastern enlargements of the European Union (EU) and the extension of the free movement of workers to the new member states' citizens unleashed significant east-west migration flows in a labor market with more than half a billion people. Although many old member states applied transitional...

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...

This paper examines the determinants of long-term international migration to the UK; we explore the extent to which migration is driven by macroeconomic variables (GDP per capita, unemployment rate) as well as law and policy (the existence of "free movement" rights for EEA nationals). We find a...

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 end of free movement and the introduction of the post-Brexit migration system represents a major structural change to the UK labour market. We provide a descriptive assessment of the impact on a sectoral basis. We examine how overall labour force growth has differed between sectors, both...

We investigate the impact of immigration on productivity in the UK, using newly published ONS data on employees of non-UK origin by region and sector. Consistent with earlier research, we find some evidence of a positive association between non-EU migration and productivity, and some weaker...

The end of free movement and the introduction of the post-Brexit migration system represent the most important changes to the UK migration system in half a century. Coinciding with the aftereffects of the pandemic, the result has been very large changes both to the numbers of those coming for...

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...
