This article reviews the growing economics literature that studies the politico-economic impacts of heterogeneity in moral boundaries across individuals and cultures. The so-called universalism-versus-particularism cleavage has emerged as a main organizing principle behind various salient...

We propose a framework where perceptions of uncertainty are driven by the interaction between cognitive constraints and the way that people learn about it--whether information is presented sequentially or simultaneously. People can learn about uncertainty by observing the distribution of...

How quickly does marginal utility fall with increasing consumption? It depends on the dimension along which we consider concavity of the utility function. This paper estimates the distribution of heterogeneous curvature parameters in individuals' utility functions from hypothetical choice data,...

The influence of behavioral biases on aggregate outcomes like prices and allocations depends in part on self-selection: whether rational people opt more strongly into aggregate interactions than biased individuals. We conduct a series of betting market, auction and committee experiments using 15...

We propose that a person's desire to consume an object or possess an attribute increases in how much others want but cannot have it. We term this motive superiority-seeking, and show that it generates preferences for exclusion that help explain a host of market anomalies and make novel...

Does mental accounting matter for total consumption expenditures? We exploit a unique setting in which individuals exogenously received a new credit card, without requesting one. Using random variation in the time of receipt we show that individuals temporarily increase total consumption...

We investigate how locus of control beliefs - the extent to which individuals attribute control over events in their life to themselves as opposed to outside factors - affect prosocial behavior and the private provision of public goods. We begin by developing a conceptual framework showing how...

In an experiment that elicits subjects' willingness to pay (WTP) for the outcome of a lottery, we confirm the fourfold pattern of risk attitudes described by Kahneman and Tversky. In addition, we document a systematic effect of stake sizes on the magnitude and sign of the relative risk premium,...

We measure individual-level loss aversion using three incentivized, representative surveys of the U.S. population (combined N=3,000). We find that around 50% of the U.S. population is loss tolerant, with many participants accepting negative-expected-value gambles. This is counter to earlier...

The impact of exposure to a major unanticipated natural disaster on the evolution of survivors' attitudes toward risk is examined, exploiting plausibly exogenous variation in exposure to the 2004 Indian Ocean tsunami in combination with rich population-representative longitudinal survey data...
