We report the results of an experimental test for feedback-conditional regret effects using a naturally occurring gamble. The properties of this gamble are likely to engage decision-makers to a greater extent than conventional abstract laboratory gambles, and be more generally exhibited by real...

We studied the hypothesis that social value orientations are expressed automatically in behavior, as would be suggested by the social intuitionist model. We compared automatic and more deliberated decisions in the dictator game and confirmed that social values determine behavior when responses...

We explore how risk-taking in the card game contract bridge, and in a financial gamble, correlate with variation in the dopamine receptor D4 gene (DRD4) among serious tournament bridge players. In bridge risk-taking, we find significant interactions between genetic predisposition and skill....

We design a laboratory experiment to identify whether a preference for randomization defines a stable type across different choice environments. In games and individual decisions, subjects face twenty simultaneous repetitions of the same choice. Subjects can randomize by making different choices...

We conducted a set of experiments to compare the effect of ambiguity in single person decisions and games. Our results suggest that ambiguity has a bigger impact in games than in ball and urn problems. We find that ambiguity has the opposite effect in games of strategic substitutes and...

This paper experimentally studies an essential institutional feature of matching markets: Randomization of allocation priorities. I compare single and multiple randomization in the student assignment problem with ties. The Gale-Shapley deferred acceptance algorithm is employed after...

Social lotteries are lotteries that are played along with someone else. The experimental literature indicates that risk attitudes depend on how one's situation in the safe alternative compares to that of a peer. Evaluation of the risky alternative also depends on whether the lottery gives equal...

We report the results from a set of experiments conducted to test the effect of ambiguity on individual behaviour in games of strategic complements and strategic substitutes. We test whether subjects' perception of ambiguity differs when faced by a local opponent as opposed to a foreign one....

This paper investigates if and how other-regarding preferences governing giving decisions in dictator games are affected in risky environments in which the payoff of the recipient is random. We demonstrate that, whenever the risk is actuarially neutral, the donation of dictators with a purely ex...

A subject brackets two decisions if she "choose[s] an option in each case without full regard to the other." Although in most situations such behavior is unlikely to be optimal, it is well documented in experiments where subjects make decisions in the absence of strategic considerations. This...
