Recently proposed models of risky choice imply systematic violations of transitivity of preference. Five studies explored whether people show patterns of intransitivity predicted by four descriptive models. To distinguish ?true? violations from those produced by ?error,? a model was fit in which...

This paper analyzes the effect of information overload on preference or aversion for variety. According to the model, a rational decision maker who suffers from information overload, faces a two-stage decision process, and is choosing from a set of unknown goods will find it optimal at some...

This paper focuses on information acquisition and individual decision making in ambiguous situations and presents a novel experimental design which may help to tackle open questions from a fresh perspective. Instead of giving subjects the choice between risky and ambiguous Ellsberg urns, we let...

This paper experimentally investigates individual information acquisition and decisions in ambiguous situations in which the degree of ambiguity can endogenously and individually be decreased by the subjects. In particular, I analyze how risk aversion, ambiguity attitude and personality traits...

Time preferences drive decisions in many economic situations, such as investment contexts or salary negotiations. These situations are characterized by a very short time frame for decision making. Preferences are potentially susceptible to the confounding effects of time pressure, as proposed by...

There are many reasons to suspect that benefit-cost analysis applied to environmental policies will result in policy decisions that will reject those environmental policies. The important question, of course, is whether those rejections are based on proper science. The present paper explores...

Concern about potential free riding in the provision of public goods has a long history. More recently, experimental economists have turned their attention to the conditions under which free riding would be expected to occur. A model of free riding is provided here which demonstrates that...

We examine the risky choices of pairs of contestants in a popular radio game show in France. At one point during the COVID-19 pandemic the show, held in person, had to switch to an all-remote format. We find that such an exogenous change in social context affected risk-taking behavior. Remotely,...

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...

Ever since the emergence of economics as a distinct scientific discipline, policy makers have turned to economic models to guide policy interventions. If policy makers seek to enhance growth of an open capitalist economy, they have to take into account, firstly, the uncertainties,...
