We exploit rules of class formation to identify the causal effect of increasing the number of immigrants in a classroom on natives test scores, keeping class size constant (Pure Composition Effect). We explain why this is a relevant policy parameter although it has been neglected so far. We show...

Non-cognitive skills programs may be an important policy option to improve the academic outcomes of adolescents. In this paper, we evaluate experimentally the EPIS program, which is based on bi-weekly individual or small-group non-cognitive mediation short meetings with low-performing students....

Using data from the 1997 and 2002 waves of the German Socio-Economic Panel and from official statistics, I study whether natives are less supportive of state help for the unemployed in regions where the share of foreigners among the unemployed is high. Unlike previous studies, I use...

We extend the Altonji and Card (1991) framework for analysing the impact of immigrants on natives' wages from two to three labour types and estimate reduced form wage equations for The Netherlands, United Kingdom and Norway. We find very small effects on natives' wages and no dominant robust...

This paper assesses estimates of immigrant intergenerationa l mobility that are based on aggregate data sources. We show that aggregation bias strongly inflates estimates of the relationship between immigrants' educational attainment and the educational attainment of their children. Compared to...

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...

Using longitudinal employment register data this study analyzes the development of outcomes of male foreign workers from all important sending countries across time. Cohort analyses on persons entering the German labour market between 1995 and 2000 show significant differences in the...

In 2011, German police accidentally stumbled upon a previously unknown right-wing extremist group called the National Socialist Underground (NSU). Further investigations implicated the group in previously unexplained murders of mostly ethnically Turkish individuals and in other crimes targeting...
