Stephen Lee’s Monitoring Immigration Enforcement offers a promising prescription for resolving the long-standing tension between the workplace enforcement priorities of the Department of Homeland Security (“DHS”) and the efforts by the Department of Labor (“DOL”) to protect the rights...

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...

This paper provides a comprehensive description of the nature and extent of ethnic segregation in Germany. Using matched employer-employee data for the universe of German workers over the period 1975 to 2008, I show that there is substantial ethnic segregation across both workplaces and...

This paper investigates the effects of the introduction of a statutory minimum wage in Germany on the wages and employment of migrants. Migrants are an overrepresented group in the low-wage sector and can be expected to particularly benefit from a minimum wage. We combine a "differential trend...

The assumption that all migrations are permanent, which pervaded the early microdata-based research on immigrant career profiles, is not supported by the empirical evidence. Rather, many - if not most - migrations appear to be temporary. In this paper, therefore, we illustrate the estimation...
