In this paper we are studying a multiple player two-armed bandit model with two risky arms in discrete time. Players have to find the superior arm and can learn from others' history of choices and successes. In equilibrium, there is no con?ict between individual and social rationality. If agents...

This paper investigates the effects of neighborhood size and network structure on strategic experimentation. We analyze a multi-arm bandit game with one safe and two risky alternatives. In this setting, risk taking produces a learning externality and an opportunity for free riding. We conduct a...

Gender-specific patterns of self-selection into competitive and cooperative environments may have multiple reasons. One of the most prominent explanations to this point is, that there are inherent differences between men and women when it comes to preferences regarding competition. We take a...

Small firms are seen as important drivers of dynamics and innovation. They need to be particularly flexible and be able to react quickly to new challenges. This paper uses the latest change in dismissal protection legislation in Germany as a natural experiment and tries to find causal effects on...

Public child care is expected to assist families in reconciling work with family life. Yet, empirical evidence for the relevance of public child care to maternal employment is inconclusive. We exploit the introduction of a legal claim to a place in kindergarten in Germany, which was contingent...

There is widespread concern that major cities and their inhabitants are highly vulnerable to transit strikes. Governments in many countries have addressed this concern by limiting the right of transit workers to strike. Whether or not this can be justified depends, in turn, on whether strikes by...

Sick-pay is a common provision in labor contracts. It insures workers against a sudden loss of income due to unexpected absences and helps them smooth consumption. Therefore, many governments find sick-pay socially desirable and choose to mandate its provision. But sick-pay is not without its...

Germany has the lowest birth rate among all OECD countries. To encourage fertility, the federal government has recently introduced a set of reforms that led to a substantial expansion of public child care for under three year old children. Using administrative county-level data, we exploit...

What role does affordable and widely available public child care play for fertility? We exploit a major German reform generating large temporal and spatial variation in child care coverage for children under the age of three. Our precise and robust estimates on birth register data reveal that...
