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...

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 study the problem of elicitation of subjective beliefs of an agent when the beliefs are ambiguous (the set of beliefs is a non-singleton set) and the agent's preference exhibits ambiguity aversion; in particular, as represented by alpha-maxmin preferences. We construct a direct revelation...

In this paper we show that if a very small, exogenously given probability of terminating the exchange is introduced in an elementary investment game, reciprocators play more often the defection strategy. Everything happens as if they hide behind probabilities in order to break the trust...

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 investigates whether language priming activates different cultural identities and norms associated with the language communicated; bilingual subjects are given Chinese instructions in the Chinese treatment and English instructions in the English treatment. The main findings are: (1) in...

We refine the understanding of individual preferences across social lotteries, whereby the payoffs of a pair of subjects are exposed to random shocks. We find that aggregate behavior is ex-post and ex-ante inequality averse, but also that there is a wide variety of individual preferences and...
