We experimentally investigate spillover effects of affirmative action policies on team performance and the willingness to work in teams. We find that such policies in form of gender quotas do not harm performance and cooperation within teams, and do not discourage selection into teams.

We experimentally investigate spillover effects of affirmative action policies in tournaments on subsequent team performance and the willingness to work in teams. In three different team environments, we find that such policies in form of gender quotas do not harm performance and cooperation...

We study escalation and aggression in an experimental first-strike game in which two participants play multiple rounds of a money-earning task. In each round, both players can spend money to accumulate weapons. The player with more weapons can spend money to strike against the other player,...

We study the effects of voluntary participation on cooperation in collective action problems. Voluntary participation may foster cooperation through a mechanism of assortative selection of interaction partners based on false consensus bias, or through a mechanism whereby the decision to not...

Fungibility of money is a central assumption in the theory of consumer choice: any unit of money is substitutable for another. This implies that the composition of income or wealth is irrelevant for consumption. We find in a field experiment that even in a simple, incentivized setup many...

We report evidence from public goods experiments with and without punishment which we onducted in Russia with 566 urban and rural participants of young and mature age cohorts. Russia is interesting for studying voluntary cooperation because of its long history of collectivism, and a huge...

Field evidence suggests that people belonging to the same group often behave similarly, i.e., behavior exhibits social interaction effects. We conduct a laboratory experiment that avoids the identification problem present in the field and allows us to study the behavioral logic of social...

Previous studies suggest that two otherwise robust 'anomalies' - preference reversals and disparities between buying and selling valuations - are eroded when respondents participate in repeated markets. We report an experiment which investigates whether this is true when factors neglected in...

Vendettas occur in many real world settings where rivals compete for a prize, e.g., winning an election or a competitive promotion, by engaging in retaliatory aggressive behavior. We present a benchmark experiment where two players have an initial probability of winning a prize. Retaliatory...

We study the effects of voluntary participation on cooperation in collective action problems. Voluntary participation may foster cooperation through an entry mechanism, which leads to assortative selection of interaction partners, or an exit mechanism, whereby the opportunity to leave the...
