We investigate international migration choices of high-skilled individuals and measure migrant selection using predicted earnings. High-skilled migrants select to destinations as predicted by Borjas' (1987) model of migration choices. Migrants to less equal countries are positively selected,...

We measure selection of high-skilled migrants from Germany using predicted earnings. Migrants to less equal countries are positively selected relative to non-migrants, while migrants to more equal countries are negatively selected, consistent with the prediction in Borjas (1987). Positive...

We investigate the effect of studying abroad on international labor market mobility later in life for university graduates. As a source of identifying variation, we exploit the introduction and expansion of the European ERASMUS student exchange program, which significantly increases a student's...

I investigate whether faculty quality and department size affect the productivity of scientists. The endogeneity problems related to estimating these effects are addressed by using the dismissal of science professors by the Nazi government as a source of exogenous variation. While local faculty...

Large-scale increases in discrimination can lead to dismissals of highly qualified managers. We investigate how expulsions of senior Jewish managers, due to rising discrimination in Nazi Germany, affected large corporations. Firms that lost Jewish managers experienced persistent reductions in...

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 study how performance metrics affect the allocation of talent. We exploit the introduction of a new measure of scientific performance: citation metrics. For technical reasons, the first citation database only covered citations from certain journals and years. Thus, only a subset of citations...

We study the role of professional networks in facilitating emigration of Jewish academics dismissed from their positions by the Nazi government. We use individual-level exogenous variation in the timing of dismissals to estimate causal effects. Academics with more ties to early émigrés...
