I am a research economist at the Halle Institute for Economic Research (IWH) heading the research group "Firm Dynamics and Employment". I am a Junior Research Associate at the Centre for European Economic Research (ZEW) in Mannheim and a Research Affiliate at the New Zealand Work Research Institute (NZWRI) at Auckland University of Technology.

During January to April 2022, I was visiting the University of Chicago as a Visiting Research Scholar.

I received my PhD from the University of Mannheim. Before joining IWH, I worked as a researcher at ZEW, the Institute for Employment Research (IAB) in Nuremberg, and the German Council of Economic Experts.

Many countries consolidate their police forces by closing down local police stations. Police stations represent an important and visible aspect of the organization of police forces. We provide novel evidence on the effect of centralizing police offices through the closure of local police stations on crime outcomes. Combining matching with difference-in-differences specification, we find an increase in reported car theft and burglary in residential properties. Our results are consistent with a negative shift in perceived detection risks and are driven by heterogeneous station characteristics. We can rule out alternative explanations such as incapacitation, crime displacement, and changes in police employment or strategies at the regional level. We argue that criminals are less deterred due to a lower visibility of the local police.
