I am a researcher in the field of empirical labor economics mostly working on minimum wages, labor demand and females in managerial positions.
Currently, I am an Acting Professor for Labor Economics at the Julius Maximilian University of Wuerzburg. In addition, I am a senior economist at the Institute for Employment Research (IAB), a Research Fellow at IZA, and a Research Associate at the Labor and Socio-Economic Research Center (LASER) of the University of Erlangen-Nuremberg.
Wage inequality in Germany
after the minimum wage introduction
(with Thorsten Schank)
We show that the German minimum wage led to a significant reduction in monthly wage inequality (see graph above). The decrease in inequality already started to emerge in the years prior to the minimum wage introduction, which is mostly explained by compositional changes in the types of jobs (full-time, part-time, minijobs).
Measurement error in bite-dependent minimum wage evaluations
(with Christian Westermeier)
We assess the role of measurement error in wage data, which leads to contaminated treatment assignment in bite-dependent minimum wage evaluations. As a consequence, treatment effects attenuate (see graph above). However, when the analysis is conducted at an aggregated level (firms or regions), measurement error can even lead to an overestimation of the true treatment effect.
Labor Demand on a Tight Leash
(with Martin Popp)
We show that labor market tightness has a significantly negative impact on firms' labor demand. The graph above shows the consequences for employment growth in Germany during the 2010s, when labor market tightness doubled in course of a rising demand for workers. Employment would have grown by an additional 1.1 million jobs if tightness had not increased during the period of analysis.
