We look at the links between the Digit Ratio - the ratio of the length of the index finger to the length of the ring finger – for both right and left hands, and giving in a Dictator Game. Unlike previous studies with exclusively Caucasian subjects, we recruited a large, ethnically diverse...

We study risk taking on behalf of others in an experiment on a large random sample. The decision makers in our experiment are facing high-powered incentives to increase the risk on behalf of others through hedged compensation contracts or with tournament incentives. Compared to a baseline...

We explore the interaction between fairness attitudes and reference dependence both theoretically and experimentally. Our theory of fairness behavior under reference-dependent preferences in the context of ultimatum games, defines fairness in the utility domain and not in the domain of dollar...

We investigate risk-sharing without commitment by designing an experiment to match a simple model of voluntary insurance between two agents when aggregate income is constant. Participants are matched in pairs. Each period, they receive their income with or without a random component h that one...

We experimentally investigate cooperative behavior in a social dilemma situation, where the socially efficient outcome may be encouraged by risk aversion and/or inequality aversion.The first part of our experiment is devoted to the elicitation of subjects' aversion profile, taking care to not...

Social preference models were originally constructed to explain two things: why people spend money to affect the earnings of others and why the income of others influences reported happiness. We test these models in a novel experimental situation where participants face a risky decision that...

Buffer-stock versions of the dynamic stochastic optimizing model of saving are now standard in the consumption literature. This paper builds theoretical foundations for rigorous understanding of the main characteristics of buffer stock models, including the existence of a target level of wealth...

The budget constraint requires that, eventually, consumption must adjust fully to any permanent shock to income. Intuition suggests that, knowing this, optimizing agents will fully adjust their spending immediately upon experiencing a permanent shock. However, this paper shows that if consumers...

We consider an economy where individuals privately choose effort and trade competitively priced securities that pay off with effort-determined probability. We show that if insurance against a negative shock is sufficiently incomplete, then standard functional formrestrictions ensure that...
