When we take a cab we may feel cheated if the driver takes an unnecessarily long route despite the lack of a contract or promise to take the shortest possible path. Is our decision to take the cab affected by our belief that we may end up feeling cheated? Is the behavior of the driver affected...

The creation of the euro should now be recognized as an experiment that has led to the sovereign debt crisis in several countries, the fragile condition of major European banks, the high levels of unemployment, and the large trade deficits that now exist in most Eurozone countries. Although the...

Can measured risk attitudes and associated structural models predict insurance demand? In an experiment (n = 1,730), we elicit measures of utility curvature, probability weighting, loss aversion, and preference for certainty and use them to parameterize seventeen common structural models (e.g.,...

Innovation is important for firm performance and broader economic growth. But breakthrough innovations necessarily require greater risk-taking than more incremental approaches. To understand how managers respond to uncertainty when making research and development decisions, we conducted three...

The favorite-longshot bias describes the longstanding empirical regularity that betting odds provide biased estimates of the probability of a horse winning--longshots are overbet, while favorites are underbet. Neoclassical explanations of this phenomenon focus on rational gamblers who overbet...

Are individuals expected utility maximizers? This question represents much more than academic curiosity. In a normative sense, at stake are the fundamental underpinnings of the bulk of the last half-century's models of choice under uncertainty. From a positive perspective, the ubiquitous use of...

This paper demonstrates gender differences in risk aversion and ambiguity aversion. It also contributes to a growing literature relating economic preference parameters to psychological measures by asking whether variations in preference parameters among persons, and in particular across genders,...

Social identities prescribe behaviors for people. We identify the marginal behavioral effect of these norms on discount rates and risk aversion by measuring how laboratory subjects' choices change when an aspect of social identity is made salient. When we make ethnic identity salient to...

We conduct a stated-choice experiment where respondents are asked to rate various insurance products aimed to protect against financial risks associated with long-term care needs. Using exogenous variation in prices from the survey design, and objective risks computed from a dynamic...

Incentive schemes that reward participants based on their relative performance are often thought to be particularly risk-inducing. Using a novel, real-effort task experiment in the laboratory, we find that the relationship between incentives and risk-taking is more nuanced and depends critically...
