About Me

I am Junior-Professor for personnel economics at the University of Cologne and research affiliate of CEPR. 

I study how firms can find the right HR (method: matching experimental and field data; field experiments in firms),  the causal effects of HR practices on performance (method: field experiments in firms), and the effects of downsizing. I analyze downsizing from different perspectives. Depending on the perspective, I apply different empirical methods and datasets. Using large hand-collected and accounting datasets, I study how media report on downsizing and how firms perform after downsizing. I utilize detailed internal data from one firm to investigate how workplaces perform after downsizing announcement, and analyze using field and lab experiments how non-fired workers respond to layoff.
