The Gender Gap in Earnings Losses after Job Displacement


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.

Who Suffers the Greatest Loss? Costs of Job Displacement for Migrants and Natives


We are the first to provide empirical evidence on differences in the individual costs of job loss for migrants compared to natives in Germany. Using linked employer-employee data for the period 1996-2017, we compute each displaced worker’s earnings, wage, and employment loss after a mass layoff in comparison to a matched, nondisplaced, control worker. We find that migrants face substantially higher earnings losses than natives due to both higher wage and employment losses. Differences in individual characteristics and differential sorting across industries and occupations can fully explain the gap in wage losses but not the employment gap after displacement.

Crossing Borders: Labor Market Effects of European Integration


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.
