The effects of the three-point rule in first league German soccer are tested empirically and compared to games from the German cup-competition. The inclusion of cup games ensures that changes in league games can be attributed to the three-point rule. As a result of their relative devaluation,...

We report results from a Cournot triopoly experiment with different subject pools: German students, Malaysian students, and Malaysian managers. While German students play Nash, we reject the hypothesis that both Malaysian students and managers select the Nash quantity. Moreover, Malaysian...

This study investigates the impact of pre-play communication on the outcomes in Cournot duopoly and triopoly experiments, using both students and managers as subjects. Communication is implemented by two different devices, a 'standardized-communication' and a free-communication device. We find...

What makes you a successful cooperator? Using data from the British television game show ``Golden Balls'' we analyze a prisoner's dilemma game and its pre-play. We find that players strategically select their partner for the PD, e.g., they bear in mind whether contestants lied. Players'...

Explaining the evolution and maintenance of cooperation among unrelated individuals is one of the fundamental problems in biology and the social sciences. Recent experimental evidence suggests that altruistic punishment is an important mechanism to maintain cooperation among humans. In this...

We study the division of trade surplus in a competitive market environment by conducting a natural field experiment on German eBay. Acting as a seller, we offer Amazon gift cards with face values of up to 500 Euro. Randomly arriving buyers, the subjects of our experiment, make price offers...

We conduct an artefactual field experiment to study whether the individual preferences and propensity to cooperate of temporary workers differ from permanent contract workers. We find that temporary and permanent contract workers have different other-regarding preferences, but display similar...

The marked difference in the development of the North and the South of Italy represents a prototypical case of seemingly intractable within-country disparities. Recent research found that a plausible determinant of this socio-economic gap would be a difference in the ability to cooperate....

We document an increase in the scoring probability from penalties in soccer, which separates the time period before 1974 significantly from that after 1976: the scoring probability increased by 11%.We explain this finding by arguing that the institution of penalty-shooting before 1974 is best...

We report the results of a field experiment with bicycle messengers in Switzerland and the United States. Messenger work is individualized enough that firms can choose to condition pay on it, but significant externalities in messenger behavior nonetheless give their on-the-job interactions the...
