For decades, experimental economics has been very interested in behavior that could be characterized as practicing solidarity (although the term is rarely used). Solidarity is a key concept in Catholic Social Teaching. This paper builds a bridge between these two endeavors that, thus far, had...

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...

Both in the US and in Europe, antitrust authorities prohibit merger not only if the merged entity, in and of itself, is no longer sufficiently controlled by competition. The authorities also intervene if, post merger, the market structure has changed such that "tacit collusion" or "coordinated...

If accurate prediction is the goal, and if information about the unconditional probability of the predicted event is available, a strong case can be made for using this information, i.e. for a Bayesian approach to inference. Not so rarely, the law calls for accurate prediction, e.g. if a bailing...

A random shock excludes reverse causality and reduces omitted variable bias. Yet a natural experiment does not identify random exposure to treatment, but the reaction to a random change from baseline to treatment. A lab experiment comparing higher certainty with higher severity of punishment for...

Judges are obliged to give reasons for their decisions. A set of formal and informal norms specifies how this is to be done. These norms serve a whole array of purposes. This paper shows that one substantial effect is on decision quality. The effect can even be demonstrated on an ad hoc basis....

The law is not a bunch of scattered rules, it is a body. This simple statement suffices to demonstrate that consistency is crucial for the law. Esteemed philosophers radicalise the statement: If it stops being consistent, to them the law is no longer the law. Consequently, consistency must be an...
