This paper explores the impact of undocumented as opposed to documented immigration in a model featuring search frictions and non-random hiring that is consistent with novel empirical evidence presented. In this framework, undocumented immigrants' wages are the lowest of all workers due to their...

We analyze the impact of the immigration influx that took place during the years 2000-2007 in Greece on labor market outcomes. We employ a search and matching framework that allows for skill heterogeneity and differential unemployment income (search cost) between immigrants and natives. Within...

This paper analyzes the impact of immigration on Germany's labor market in the context of the recent 2004 and 2007 EU enlargements. In order to measure the effect of immigration supply shocks on individuals' labor outcomes, this paper uses economist George Borjas's "Skill-Group" approach, which...

This paper analyzes the impact of the skill composition of migration flows on the host country’s labor market in a specific factors two-sector model with heterogeneous labor (low-, medium-, and highly-skilled) and price- and wage-setting behavior. The low- and medium-skilled labor markets are...

It documents that immigrant workers initially earn on average 20 percent less than native workers with otherwise identical characteristics. The gap is smaller for...

The effect of foreign labor on native employment within an occupation depends on native labor supply to that occupation – which is rarely directly measured – even if native and foreign labor are perfect substitutes in production. This paper uses two natural quasi-experiments to directly...
