Assar Lindbeck and Denis Snower investigate the effects of multitasking and teamwork on the viability of centralised bargaining. They emphasize that workers likely have private information concerning their task mix when multitasking plays a significant role in the production process. They try to...

We exploit regional differences in labour market density to conduct a simple empirical test of dynamic monopoly and selection wage theories. According to selection wage theories employers offer above-average wages in order to attract more applicants. This allows them to be choosier and to select...

Arent and Nagl (2013) use the BA Employment panel 1998-2007 to identify effects of the German Hartz reform. Their findings suggest that the reform caused a considerable reduction of wages. Our replication of their study suggests that their clear and strong conclusions are driven by a too coarse...

This papers describes an estimator for a standard state-space model with coefficients generated by a random walk that is statistically superior to the Kalman filter as applied to this particular class of models. Two closely related estimators for the variances are introduced: A maximum...

This article analyzes the impact of five major expansions in maternity leave coverage in Germany on mothers’ labor market outcomes after childbirth. To identify the causal impact of the reforms, we use a difference-in-difference design that compares labor market outcomes of mothers who give...
