Welcome!

I am a postdoctoral researcher at the Institute for Applied Microeconomics at the University of Bonn. I am also a research associate in the research group of the director at the Institute for Employment Research (IAB), and a visiting research affiliate at the IZA.

I am a member of the Collaborative Research Center Transregio 224 and of the Cluster of Excellence ECONtribute: Markets & Public Policy.

My main field is labor economics, with a focus on immigration and economics of gender. My research is motivated by understanding what happens to workers’ careers if they are hit by labor market shocks.

The Gender Gap in Earnings Losses after Job Displacement

Abstract

We compare men and women who are displaced from similar jobs by applying an event study design combined with propensity score matching and reweighting to administrative data from Germany. After a mass layoff, women’s earnings losses are about 35% higher than men’s, with the gap persisting five years after displacement. This is partly explained by women taking up more part-time employment, but even women’s full-time wage losses are almost 50% higher than men’s. Parenthood magnifies the gender gap sharply. Finally, displaced women spend less time on job search and apply for lower-paid jobs, highlighting the importance of labor supply decisions.

Crossing Borders: Labor Market Effects of European Integration

Abstract

This paper studies the labor market effects of out- and in-migration in the context of cross-border commuting. It investigates an EU policy reform that granted Czech citizens full access to the German labor market beginning in 2011, resulting in a Czech commuter outflow across the border to Germany. Exploiting the fact that this migrant flow affected the Czech and German border regions in particular, I combine a difference-in-differences approach with propensity score matching to estimate the labor market effects of the policy reform in both countries. Using a novel dataset on Czech regions, I show that municipalities in the Czech border region experienced a decline in unemployment rates as a result of the worker outflow, while vacancies increased. For German municipalities, I find no aggregate effects on native employment and wages. At the establishment level, my results suggest small shifts in the workforce composition and an increase (decrease) in establishment entries (exits). Finally, my analysis of a cohort of native German workers reveals few effects on their employment and wages.

Job Displacement and Migrant Labor Market Assimilation

Abstract

This paper sheds new light on the barriers to migrants’ labor market assimilation. Using 1997-2016 linked employer-employee data for Germany, we estimate dynamic difference-in-differences regressions and show that migrants have about 40% higher earnings losses from job displacement than natives. Differences in pre-displacement characteristics explain most of the migrant-native gap in wage losses but only about half of the gap in re-employment success. While migrants search for different types of jobs, differences in search behavior cannot fully account for differences in realized labor market outcomes. One explanation for this is that migrants are less successful in taking advantage of favorable local labor market conditions.

Hiring and the Dynamics of the Gender Gap

Abstract

To understand how the gender wage gap interacts with job mobility, we examine the internal and external labor market responses to exogenous hiring shocks by gender. Using matched employer-employee data from Germany, our empirical strategy leverages 50,000 unexpected worker deaths to characterize how firms respond to exogenous vacancies of positions formerly held by male or female workers. We find that female replacement workers take up positions with lower average existing wages regardless of the gender of their predecessors. Furthermore, female replacement workers have significantly lower starting wages than male replacement workers, by between 15 to 19 log points, and their wages grow much more slowly over time.
