We study cheating as a collective-risk social dilemma in a group setting in which individuals are asked to report their actual outcomes. Misreporting their outcomes increases the individual's earnings but when the sum of claims in the group reaches a certain threshold, a risk of collective...

The prospect of receiving a monetary sanction for free riding has been shown to increase contributions to public goods. We ask whether the impulse to punish is unresponsive to the cost to the punisher, or whether, like other preferences, it interacts with prices to generate a conventional demand...

The fact that many people take it upon themselves to impose costly punishment on free riders helps to explain why collective action sometimes succeeds despite the prediction of received theory. But while individually imposed sanctions lead to higher contributions in public goods experiments,...

We conduct an experiment where subjects are matched in groups of three and vote on a moral transgression. Analyzing different voting rules, the frequency of votes for the moral transgression increases with the number of votes required for it. This effect persists when considering pivotal votes...

The enforcement of social norms often requires that unaffected third parties sanction offenders. Given the renewed interest of economists in norms, the literature on third party punishment is surprisingly thin, however. In this paper, we report on the results of an experiment designed to...

Opinion is divided on whether it is better to have a single world money or variable exchange rates. Pope, Selten and von Hagen (2003) propose that fresh light would be shed via an analysis that allows for seven complexity impacts on the exchange rate that are underplayed (where not entirely...

A person is said to be `trust responsive` if she fulfils trust because she believes the truster trusts her. The experiment we report was designed to test for trust responsiveness and its robustness across payoff structures, and to disentangle it from other possible factors making for...

We conduct a survey and find that 47% of respondents state they would sanction free riders in a team production scenario even though the respondent was not personally affected and no direct benefits could be expected to follow an intervention. To understand this phenomenon, we define social...
