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...

In an experiment on the large language model GPT-4o, a supplier always makes a higher profit if it replaces uniform contract terms with a set of terms between which the customer may choose. The extra profit results from price discrimination. There is a first order and a second order effect. The...

Building on a theoretical model we test the hypothesis that effort choices and preferences for redistribution are simultaneously determined. Using cross-country panel data from the World Value Survey, we find that it is important to model preferences for redistribution and effort choices...

Legitimacy may result from support for projects that a government implements. However, legitimacy may also result from the opportunity to participate in the selection process of projects. We tested the strength of these competing sources of legitimacy experimentally and their relationship. We...

The market for copyrights is characterised by a highly skewed distribution of profits: very few movies, books and songs generate huge profits, whereas the great bulk barely manages to recover production cost. At the moment when the owner of intellectual property grants a licence ('ex ante'),...

We study the effect of voting when insiders´ public goods provision may affect passive outsiders. Without voting insiders´ contributions do not differ, regardless of whether outsiders are positively or negatively affected or even unaffected. Voting on the recommended contribution level...

Experimental participants are more likely to follow an arbitrary rule the more of their peers do so as well. The difference between unconditional and conditional rule following is most pronounced for individuals who follow few rules unconditionally.

On the doctrinal surface, there is a deep divide between common and continental law when it comes to the origin of contractual obligations. Under continental law, in principle a unilateral promise suffices. Common law by contrast requires consideration. When it comes to deciding cases, the...

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...

Often, religion, law and tradition co-evolve. Religious precepts shape social practice, which translates into law. Yet this harmony is not universal. The Sharia guarantees daughters their share in the family estate. Yet in Pakistan, this rule clashes with tradition. While the country was jointly...
