We investigate whether there is a link between conditional cooperation and betrayal aversion. We use a public goods game to classify subjects by type of contribution preference and by belief about the contributions of others; and we measure betrayal aversion for different categories of subject....

We study experimentally the protection of property in five widely distinct countries - Austria, Mexico, Mongolia, South Korea and the United States. Our main results are the correlations between experimental choices with indicators regarding the security of property, trust and the quality of...

Both in the field and in the lab, participants frequently cooperate, despite the fact that the situation can be modelled as a simultaneous, symmetric prisoner's dilemma. This experiment manipulates the payoff in case both players defect, and explains the degree of cooperation by a combination of...

Punishees regularly ask for justification. But is justification also effective? To answer this question under controlled conditions, we have conducted a public goods experiment with central punishment. The authority is neutral - she does not benefit from contributions to the public good....

Sanctions are often so weak that a money maximizing individual would not be deterred. In this paper I show that they may nonetheless serve a forward looking purpose if sufficiently many individuals are averse against advantageous inequity. Using the Fehr/Schmidt model (QJE 1999) I define three...

Evidence from an experiment investigating the house money effect in the context of a public goods game is reconsidered. Analysis is performed within the framework of the panel hurdle model, in which subjects are assumed to be one of two types: free-riders, and potential contributors. The effect...

We consider the interaction of intrinsic motivation and concerns for social approval in a laboratory experiment. We elicit a proxy for Fairtrade preferences before the experiment. In the experiment, we elicit willingness to pay for conventional and Fairtrade chocolate. Treatments vary whether...

Apparently judges' decisions are not motivated by maximizing their own profit. The literature uses two strategies to explain this observation: judges care about the long-term monetary consequences for themselves, or individuals who are more strongly motivated by the common good self-select into...

We study a laboratory social dilemma game in which incentives to steal from others lead to the socially inefficient diversion of resources from production unless the members of a given mini-society can abide by norms of non-theft or engage in low cost collective protection of their members'...
