About Me

I am Associate Professor for Strategy at the University of Cologne and research affiliate of CEPR and the Max Planck Institute for Research on Collective Goods. 
In my research, I study the causal effects of management practices (e.g., bonus schemes, employee referral programs or managerial attention) on firm performance in field experiments in firms. Moreover, I study the effects of downsizing. I analyze downsizing from different perspectives, applying 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 perform after witnessing a co-worker’s layoff.
