Low-skilled immigrants indirectly affect public finances through their effect on native wages & labor supply. We operationalize this indirect fiscal effect in various models of immigration and the labor market. We derive closed-form expressions for this effect in terms of estimable statistics....

We characterize intergenerational mobility in Germany using census data on educational attainment and parental income for 526,000 children. Our measure of educational attainment is the A-Level degree, a requirement for access to university. A 10 percentile increase in the parental income rank is...

Germany has become the second-most important destination for migrants worldwide. Using all waves from the microcensus, we study their labor market integration over the last 50 years, and document key differences to the US case. While the employment gaps between immigrant and native men decline...

We investigate the hypothesis of failed integration and low social mobility of immigrants. For this purpose, an intergenerational assimilation model is tested empirically on household survey data and validated against administrative data provided by the Italian Embassy in Germany. In line with...

We discuss the impacts of the Russian invasion on Ukrainian science. Using newly collected data, we show that the war has already had significant effects on science in Ukraine: research papers produced by Ukrainian scientists declined by about 10%, approximately 5% of the most prolific...

We apply a monopoly trade union model and analyze employment, wage and budgetary effects of (i) an inflow of migrant workers and (ii) an increase in the labor market participation rate of migrants. Per assumption, natives and migrants solely differ with respect to the level of benefit claims in...

Estimating the returns to migration from East to West Germany, this paper focuses on pre-migration employment dynamics, earnings uncertainty, and job change in the source region. Migrants are found to be negatively selected with respect to labor market outcomes, with a large drop in earnings and...

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...

The internationalization of cities and the constitution of a new international space of power involves a much more expressive number of cities than the usual global cities. Nowadays, dozens of international organizations are composed of regional capitals, medium, and even small cities. With...
