Individuals often have to decide to which degree of risk they want to expose others, or how much risk to accept if their choice has an externality on third parties. One typical application is a household. We run an experiment in the German Socio-Economic Panel with two members from 494...

Frequently in experiments there is not only variance in the reaction of participants to treatment. The heterogeneity is patterned: discernible types of participants react differently. In principle, a finite mixture model is well suited to simultaneously estimate the probability that a given...

In a lab experiment, we show that the willingness to pay taxes even absent enforcement is indeed pronounced....

Behavioral law and economics applies the conceptual tools of behavioral economics to the analysis of legal problems and legal intervention. These models, and the experiments to test them, assume an institution free state of nature. In modern societies, the law's subjects never see this state of...

What is the impact of caseload on judicial decision-making? Is increasing judicial staff effective in improving judicial services? To address these questions, we exploit a natural, near-randomized experiment in the Israeli judiciary. In 2012, six senior registrars were appointed in two of the...

Law is for humans. Humans suffer from cognitive limitations. Legal institutions can help humans by making these limitations irrelevant. This experiment shows that strong property rights serve this function. In theory, efficient outcomes obtain even without strong property rights. In a...

Frequently deciding legal cases requires an assessment in multiple, conceptually incompatible dimensions. Often one normative concern would call for one decision, and another normative concern for a different decision. The decision-maker must engage in balancing, with no help from overarching...

Oliver Williamson has coined the term "fundamental transformation". It captures the following situation: before they strike a deal, buyer and seller are protected by competition. Yet thereafter they find themselves in a bilateral monopoly. With common knowledge of standard preferences, both...
