We investigate experimentally the effect of consultation (unincentivized advice) on choices under risk in an incentivized investment task. We compare consultation to two benchmark treatments: one with isolated individual choices, and a second with group choice after communication. Our benchmark...

A modern, decision-theoretic framework can help clarify important practical questions of experimental design. Building on our recent work, this chapter begins by summarizing our framework for understanding the goals of experimenters and applying this to rerandomization. We then use this...

Science evolves in the long run. Law rules in the present. This potential temporal disconnect leads to a Hayekian “knowledge problem”, a challenge increasingly raised against behavioral law and economics: Empirical findings are deemed too uncertain to provide a solid basis for legal...

This paper reports an experiment designed to test whether prior consultation within a group affects subsequent individual decision making in tasks where demonstrability of correct solutions is low. In our experiment subjects considered two paintings created by two different artists and were...

We report an experiment examining risk taking and information aggregation in groups. Group members come to the table with an individual preference for a choice under risk, based on privately received information, and can share this information with fellow group members. They then make a decision...

We provide evidence that people have preferences for data privacy and show that these preferences partly reflect people's interest in controlling who receives their private information. Participants of an experiment face the decision to share validated personal information with peers. We compare...

This paper extends choice theory by allowing for the interaction between cognitive costs and imitative dynamics. The authors experimentally investigate the role of imitation when participants face a task which is costly in cognitive terms. In order to disentangle different choice dynamics, they...

We report a controlled laboratory experiment examining risk-taking and information aggregation in groups facing a common risk. The experiment allows us to examine how subjects respond to new information, in the form of both privately observed signals and signals reported from others. We find...

Although understanding preferences for privacy is of great importance to economists, businesses and politicians little is known about the factors that shape the individual willingness to share personal data. This article provides three experimental studies with a total of 470 participants that...

We report an experiment where each subject's ambiguity sensitivity is measured by an ambiguity premium, a concept analogous to and comparable with a risk premium. In our design, some tasks feature known objective risks and others uncertainty about which subjects have imperfect, heterogeneous,...
