Combining the methodologies of experiment economics and molecular genetics, we report genetic association between sex-hormone genes and ultimatum game (UG) behavior in a discovery sample from China and a replication sample from Israeli. We find that the estrogen receptor β gene (ESRβ) is...

In this short note, we show investors one way to calculate ideal investment sizing by using two rules of thumb based on a simple outline of individual risk aversion. We illustrate these two heuristics, which are not widely appreciated, with thought experiments involving coin flips and ketchup &...

Experiments typically rely on small payments to incentivize participants. This works if participants view these payments as fungible with their own money, but if participants view the payments as a windfall, they may behave differently in experiments than in real life. We modify standard risky...

Purpose The relevance of present consumption bias on personal finance has been confirmed in several studies and has important theoretical and practical implications. It has important, measurable implications when analyzing commitment or self-control, adherence to healthy habits (e.g. exercising...

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 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...

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....

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...

This paper considers the design problem of selling a unit good to a prospect theory buyer, with non-negative constraints on the realized price. When the value is private and the reservation value is 0, it is optimal for the seller to use a post binary random price mechanism, where he charges a...

A parsimonious model is used to explore the risk-bearing decision under a payoff structure that emphasizes relative performance. Equilibrium betting amounts are derived for players who start with unequal endowments and face a lottery that offers either a positive or negative expected return. If...
