Based on recent discoveries in economics, neuroscience, and psychology, we hypothesize that pure exposure to high-payoff or low-payoff gambles can change people’s subsequent reported valuations of gambles and confirm this hypothesis in a laboratory experiment. In particular, the same...

We find that financial decision-making power per se is significant in explaining individuals’ objective risk-taking behavior and subjective risk attitude. More importantly, we show that this decision power attenuates the correlation between subjective risk attitude and objective risk taking....

People who are members of a group and identify with it behave differently from people who perceive themselves as isolated individuals. This difference depends on two main factors. First, preferences over outcomes change with the degree of identification with the group. Second, this...

Previous work has shown that preferences are not always stable across time, but surprisingly little is known about the reasons for this instability. I examine whether variation in people's emotions over time predicts changes in risk attitudes. Using a large panel data set, I identify happiness,...

Our understanding of risk preferences can be sharpened by considering their evolutionary basis. The existing literature has focused on two sources of risk: idiosyncratic risk and aggregate risk. We introduce a new source of risk, heritable risk, in which there is a positive correlation between...

We introduce a model of random ambiguity aversion. Choice is stochastic due to unobserved shocks to both information and ambiguity aversion. This is modeled as a random set of beliefs in the maxmin expected utility model of Gilboa and Schmeidler (1989). We characterize the model and show that...

The risky investment game of Gneezy and Potters (1997) has been a popular tool used to estimate risk tolerance and myopic loss aversion. Holden and Tilahun (2021) tested and found that the simple one-shot version of this game that is attractive as a simple tool to elicit risk tolerance among...

People often fail to insure against catastrophes, even when insurance is subsidized. Even when insuring homes, many homeowners still underinsure the full value of their assets. Some researchers have suggested using long-term insurance contracts to reduce these insurance gaps. We examine...
