The 2004 and 2007 enlargements of the European Union were unprecedented in a number of economic and policy aspects. This essay provides a broad and in-depth account of the effects of the post-enlargement migration flows on the receiving as well as sending countries in three broader areas: labour...

This paper outlines the importance of labor mobility for the improvement in allocating and distributing economic resources. We are faced with an increasing lack of skilled workers and a growing tendency of unemployment amongst the low-skilled. A central political objective for the future will...

The economic literature has largely overlooked the importance of repeat migration. This paper studies repeat or circular migration as it is manifested by the frequency of exits of migrants living in Germany, and by the number of years being away from the host country using count data models....

This paper analyzes the reservation wages of first and second generation migrants. Based on recently collected and rich survey data of a representative inflow sample into unemployment in Germany, we empirically test the hypothesis that reservation wages increase from first to second generation...

This paper is based on recently collected and rich survey data of a representative sample of entrants into unemployment in Germany. Our data include a large number of migration variables, allowing us to adapt a recently developed concept of ethnic identity: the ethnosizer. To shed further light...

In this paper we study the economic effects of risk attitudes, time preferences, trust and reciprocity while we compare natives and second generation migrants. We analyze an inflow sample into unemployment in Germany, and find differences between the two groups mainly in terms of risk attitudes...

Whether Europe will be able to stand up to its internal and external challenges crucially depends on its ability to manage its internal mobility and inflows of international migrants. Using a unique expert opinion survey, we document that Europe needs skilled migrants, and skill mismatch is to...

While the literature has established that there is substantial and highly selective return migration, the growing importance of repeat migration has been largely ignored. Using Markov chain analysis, this paper provides a modeling framework for repeated moves of migrants between the host and...

Upon arrival in the host country, immigrants undergo a fundamental identity crisis. Their ethnic identity being questioned, they can be classified into four states - assimilation, integration, separation and marginalization. This is suggested by the ethnosizer, a newly established measure to...
