Does a high regional concentration of immigrants of the same ethnicity affect immigrant children's acquisition of host-country language skills and educational attainment? We exploit the exogenous placement of guest workers from five ethnicities across German regions during the 1960s and 1970s in...

Building on a new data set which is combined from national micro-data bases, we highlight differences in the structure of migrants to four countries, viz. France, Germany, the UK and the US, which receive a substantial share of all immigrants to the OECD world. Looking at immigrants by source...

For a long time, migration has been subject to intensive economic research. Nevertheless, empirical evidence regarding the determinants of migration still appears to be incomplete. In this paper, we analyze the effects of socio-economic and institutional determinants, especially labor-market...

We provide evidence that the robust association between cognitive skills and economic growth reflects a causal effect of cognitive skills and supports the economic benefits of effective school policy. We develop a new common metric that allows tracking student achievement across countries, over...

We analyse how institutional and political decisions are intertwined. Citizens who differ in their mobility and ability vote first on labour market integration and afterwards on education policy. The institutional decision on integration influences the succeeding education policy. More...

We conduct a survey experiment on the effect of information provision on attitudes towards immigration in Germany. The focus lies on two theory-based economic channels, labor market and welfare state concerns, and immigration policy preferences. Using probability-based representative survey...

We investigate the link between biased beliefs about immigrants, economic concerns and policy preferences. Conducting representative survey experiments with more than 8000 respondents, we first document substantial biases in respondents' beliefs about the immigrant population in various domains....

We examine the relationship between beliefs about and attitudes towards immigrants and intergroup contact between natives and migrants in eastern Germany, a region characterized by anti-immigrant sentiment. Using probability-based survey data, we randomly vary respondents' access to a signal...

We analyze a general search model with on-the-job search and sorting of heterogeneous workers into heterogeneous jobs. This model yields a simple relationship between (i) the unemployment rate, (ii) the value of non-market time, and (iii) the max-mean wage differential. The latter measure of...

We argue in favor of the shareholder model of the firm for three main reasons. First, serving multiple stakeholders leads to ill-defined property rights. What sounds like a fair compromise between stakeholders can easily evolve in a permanent struggle about the ultimate goal of the company....
