In modern societies more and more people interact with strangers in one-shot situations. In these situations it might be difficult to trust others. Yet, trust is an essential component of most economic interactions. In this paper (in a one-shot situation) an impartial third party can reward...

Tournament incentives prevail in labor markets, in particular with respect to promotions. Yet, it is often unclear to competitors how many winners there will be or how many applicants compete in the tournament. While it is hard to measure how this uncertainty affects work performance and...

Under common law, the standard remedy for breach of contract is expectation damages. Under continental law, the standard is specific performance. The common law solution is ex post efficient. But is it also ex ante efficient? We use experimental methods to test whether knowing that...

The model of time-inconsistent procrastination by O'Donoughe and Rabin shows that individuals who are not aware of their present-bias (naïve) procrastinate more than individuals who are aware of it (sophisticated) or are not present-biased (time-consistent). This paper tests this prediction. We...

In their majority, public international lawyers postulate that for a new rule of customary law to originate, two conditions must be fulfilled: there must be consistent practice, and it must be shown that this practice is motivated by the belief that such behaviour is required in law. Maurice...

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...

For a rational choice theorist, the absence of crime is more difficult to explain than its presence. Arguably, the expected value of criminal sanctions, i.e. the product of severity times certainty, is often below the expected benefit. We rely on a standard theory from behavioral economics,...

Antitrust authorities all over the world are concerned if a particularly aggressive competitor, a "maverick", is bought out of the market. Yet there is a lack of theoretical justification. One plausible determinant of acting as a maverick is behavioral: the maverick derives utility from acting...

Donors may often not be sure whether a recipient really deserves their help. Does this uncertainty deter generosity? In an experiment we find that, to the contrary, under most specifications of uncertainty, dictators give more, compared with the donation the same dictator makes to a recipient...

In three distinct disciplines, crime and punishment are studied experimentally: in empirical legal studies, in experimental economics, and an experimental criminology. These three disciplines have surprisingly little interaction. The current paper surveys the rich evidence, and discusses the...
