This paper examines the effect of peers on individual risk taking. In the absence of informational motives, we investigate why social utility concerns may drive peer effects. We test for two main channels: utility from payoff differences and from conforming to the peer. We show experimentally...

Many studies document failures of expected utility’s key assumption, the independence axiom. Here, we show that independence can be decomposed into two distinct axioms - betweenness and homotheticity - and that these two axioms are necessary and sufficient for independence. Thus, independence...

This paper presents detailed evidence about who compares to whom in terms of relative income. We rely on representative survey data on the importance of income comparisons vis-a-vis seven reference groups, allowing us to exploit within-subject heterogeneity. We explore the prevalence and...

We use data on insurance deductible choices to estimate a structural model of risky choice that incorporates "standard" risk aversion (diminishing marginal utility for wealth) and probability distortions. We find that probability distortions - characterized by substantial overweighting of small...

We use data on households' deductible choices in auto and home insurance to estimate a structural model of risky choice that incorporates "standard" risk aversion (concave utility over final wealth), loss aversion, and nonlinear probability weighting. Our estimates indicate that nonlinear...

Despite average per-capita consumption of roughly $1 per day, many Tanzanian households do not take advantage of bulk discounts for staple goods. Using transaction diaries covering nearly 57,000 purchases by 1,499 households over two weeks, we find that through bulk purchasing the average...

This paper theoretically and experimentally studies decision-making in risky and social environments. We explore the interdependence of individual risk attitudes and social preferences in form of inequality aversion as two decisive behavioral determinants in such contexts. Our model and the data...
