Ethnic groups tend to agglomerate and assemble, mostly in urban areas. While ethnic clustering is critically debated in societies and the consequences for economic outcomes are under debate in research, the process is not yet well understood. A separate literature has also examined the cultural...

Does granting citizenship at birth help immigrant children to integrate in the host country's educational system and thus, to promote their educational success? Our identification strategy is based on a reform of the German naturalization law in 2000. We exploit this natural experiment and use a...

This paper evaluates the effect of becoming citizen of the host-country at birth on educational outcomes of immigrant children in Germany. We exploit the introduction of birthright citizenship for newborn children in Germany starting on the 1st of January, 2000, to obtain...

Using an epidemiological approach, we study the cultural influence on fertility outcomes of first- and second-generation female immigrants based on a 1% sample of the German population. We proxy for culture in the country of origin using total fertility rates from the year of migration, survey...

In this paper, we provide a quantitative answer to the question what types of active labour market programmes (ALMPs) work for immigrants. From the existing literature, we identify 24 research papers estimating 79 short-run treatment effects of ALMPs on immigrants. We perform a meta-analysis of...

Using results from dynamic multinomial logit models, we calculate transition matrices between...

This paper investigates the degree of monoposony power of German employers in different industries, using a semi-structural approach based on a dynamic model of monopsonistic competition. The empirical analysis is based on a linked employer-employee data set which allows us to control for...
