Recent works have shown how tail events could account for financial anomalies such as the equity premiumpuzzle. These models do not explore, however, why investors would discount tail risk so heavily. We take on this challenge by designing a novel tail-event experiment to assess both investors'...

In this paper we use an experiment to compare a theory of risk aversion and a theory of spite as an explanation for overbidding in auctions. As a workhorse we use the second-price all-pay and the first-price winner-pay auction. Both risk and spite can be used to rationalize deviations from risk...

Both economists and psychologists are interested in understanding decision making under uncertainty. Yet, they rely on different concepts to analyse human behaviour: Economists use economic preference parameters rooted in utility theory, while psychologists use personality traits to describe...

Three determining factors for economic inequality are self-chosen effort, self-chosen risk, and external circumstances. The fairness people assign to inequalities due to effort and external circumstances is widely studied. Insights on the fairness of inequalities due to self-chosen effort and...

Overconfidence is one of the most ubiquitous cognitive bias. There is copious evidence of overconfidence being relevant in a diverse set of economic domains. In this paper, we relate the recent concept of cognitive uncertainty with overconfidence. Cognitive uncertainty represents a decision...

Experiments on intertemporal consumption typically show that people have difficulties in optimally solving such problems. Previous studies have focused on contexts in which agents are faced with risky future incomes and have to plan over long horizons. We present an experiment comparing decision...

This paper presents evidence on the role of the endowment effect in shaping the risk-taking behavior of entrepreneurs, and how the potential of losing their firms lead them to take higher risks. This study uses an experimental design with 466 entrepreneurs in Cali, Colombia. Results show that...

We argue that choices that are modified, absent any informational change, can be characterized as mistakes. In an experiment, we allow subjects to choose from budgets over binary lotteries. To identify mistakes, which we interpret as deviations from optimizing behavior, we allow subjects to...

The perception of risk affects how people behave during crises. We conduct a series of experiments to explore how people form COVID-19 mortality risk beliefs and the implications for prosocial behavior. We first document that people overestimate their own risk and that of young people, while...

We show that the disposition to focus on favorable or unfavorable outcomes of risky situations affects willingness to take risk as measured by the general risk question. We demonstrate that this disposition, which we call risk conception, is strongly associated with optimism, a stable facet of...
