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...

We use survey and experimental data to explore how effort choices and preferences for redis-tribution are linked. Under standard preferences, redistribution would reduce effort. This is different with social preferences. Using data from the World Value Survey, we find that respondents with...

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...

Jury members do not normally have the privilege of a complete, unbiased picture of the case. To make the best of patently incomplete evidence, they cannot but at least partially rely on their intuition. We provide evidence for this claim based on self-report data as well as more subtle measures...

Most apparent differences between US and continental law lose their relevance once one looks beneath the doctrinal surface and checks how doctrine plays itself out in concrete cases. One of the few exceptions is standards of proof. Not only distinguishes US law between preponderance of the...

Hardly any antitrust lawyer would deny that antitrust needs solid foundations in economics. Antitrust authorities hire economists, if they do not even haven the position of a chief economist. Antitrust not only capitalises on economic theory, but it is equally sensitive to empirical studies, be...

Broken Windows: the metaphor has changed New York and Los Angeles. Yet it is far from undisputed whether the broken windows policy was causal for reducing crime. In a series of lab experiments we show that first impressions are indeed causal for cooperativeness in three different institutional...

The most famous element in Bentham's theory of punishment, the Panopticon Prison, expresses his view of the two purposes of punishment, deterrence and special prevention. We investigate Bentham's intuition in a public goods lab experiment by manipulating how much information on punishment...
