We experimentally investigate behavior and beliefs in a sequential prisoner’s dilemma. Each subject had to choose an action as first-mover and a conditional action as second-mover. All subjects also had to state their beliefs about others’ second-mover choices. We find that subjects’...

We explore network effects on generosity for different network dimensions. To this end we elicit multiple network dimensions (friendship, social support, economic exchange, etc.) in a rural village in the Southern hemisphere and measure generosity with a sequence of dictator games conducted in...

Situations where independent agents need to align their activities to achieve individually and socially beneficial outcomes are abundant, reaching from everyday situations like fixing a time for a meeting to global problems like climate change agreements. Often such situations can be described...

This paper studies gender differences in strategic situations. In two experimental guessing games - the beauty contest and the 11-20 money request game - we analyze the depth of strategic reasoning of women and men. We use unique data from an internet experiment with more than 1,000...

We investigate the link between leadership, beliefs and pro-social behavior. This link is interesting because field evidence suggests that people's behavior in domains like charitable giving, tax evasion, corporate culture and corruption is influenced by leaders (CEOs, politicians) and beliefs...

Situations where independent agents need to align their activities to achieve individually and socially beneficial outcomes are abundant, reaching from everyday situations like fixing a time for a meeting to global problems like climate change agreements. Often such situations can be described...

We document the effectiveness of robo calls for increasing voter participation despite most published research finding little or no effect of automated calls. We establish this finding in a large field experiment in a targeted, partisan get-out-the-vote campaign. Our experimental design includes...

We conduct experimental games with police applicants in Germany to investigate whether intrinsically motivated agents self-select into public service. Our focus is on trustworthiness and the willingness to enforce norms as key dimensions of intrinsic motivation in the police context. We find...

We explore the relationship between individuals’ disposition to cooperate and their inclination to engage in peer punishment as well as their relative importance for mitigating social dilemmas. Using a novel strategy-method approach we identify individual punishment patterns and link them with...

Real-effort experiments are frequently used when examining a response to incentives. For any particular real-effort task to be well-suited for such an exercise, subjects’ cost for exerting effort must, for the range of incentives considered, result in an interior effort choice. The popular...
