How do people balance health/wealth concerns during a pandemic? And, how does the communication of this trade-off affect individual preferences? We address these questions using a field experiment involving around 2000 students enrolled in a large university in Italy. We design four treatments...

Many information structures generate correlated rather than mutually independent signals, the news media being a prime example. This paper shows experimentally that in such contexts many people neglect these correlations in the updating process and treat correlated information as independent. In...

Bayesian Updating is the dominant theory of learning in economics. The theory is silent about how individuals react to events that were previously unforeseeable or unforeseen. Recent theoretical literature has put forth axiomatic frameworks to analyze the unknown. In particular, we test if...

We study belief updating about relative performance in an ego-relevant task. Manipulating the perceived ego-relevance of the task, we show that subjects update their beliefs optimistically because they derive direct utility flows from holding positive beliefs. This finding provides a behavioral...

We extend the literature structurally estimating social preferences by accounting for the desire to adhere to social norms. Our representative agent is strongly motivated by norms and failing to account for this causes us to overestimate how much agents care about helping those who are worse...

Price surges often generate social disapproval and requests for regulation and price controls, but these interventions may cause inefficiencies and shortages. To study how individuals perceive and reason about sudden price increases for different products under different policy regimes, we...

Dark personality traits have been linked to behaviors commonly understood as unethical, such as fraud, bribe-taking, and marital infidelity. Presumably, more "light" personality traits may be associated with lesser tendencies to be unethical, but many individuals also possess both light and dark...

Preferences - concerning time, risk and social interactions - systematically shape human behavior, and contribute to differential economic and social outcomes between the genders. Here, we present a global investigation of gender differences in six fundamental preferences. Our data consist of...

Little is known about how gamblers estimate probabilities from multiple information sources. This paper reports on a preregistered study that administered an incentivized Bayesian choice task to n=465 participants (self-reported gamblers and non-gamblers). Our data failed to support our main...
