Optimistic beliefs affect important areas of economic decision making, yet direct knowledge on how belief biases operate remains limited. To better understand these biases I introduce a theoretical framework that trades off anticipatory benefits against two potential costs of forming biased...

The psychology literature provides ample evidence that people have difficulties taking the perspective of less-informed others. This paper presents a controlled experiment showing that this "curse of knowledge" can cause comparative overconfidence and overentry into competition. In a broader...

An individual is affected by the curse of knowledge when he fails to appreciate the viewpoint of a lesser-informed agent. In contrast to a rational person, the cursed individual behaves as if part of his private information were common knowledge. This systematic cognitive bias alters many...

Information frictions play an important role in many theories of expectation formation. We use a survey experiment to generate direct evidence on how people select, acquire and process information. Participants can buy different information signals that could help them forecast future national...

We commonly think of information as an instrument for better decisions, yet evidence suggests that people often decline free information in non-strategic scenarios. This paper provides a theory for how a dynamically-consistent decision maker can be averse to partial information as a consequence...

Discrimination is a pervasive aspect of modern society and human relations. Statistical discrimination theory suggests that profit-maximizing employers should use all the information about job candidates, including information about group membership (e.g., race or gender), to make accurate...

Many decision contexts require economic actors to learn from something they do not see, yet corresponding evidence on people's cognition is scarce. In a tightly structured and transparent laboratory experiment, many subjects fully neglect what they do not see. A series of treatment variations...

Overall, 72 subjects invest their endowment in four risky assets. Each com-bination of assets yields the same expected return and variance of returns. Illusion of expertise prevails when one prefers nevertheless the self-selected portfolio. After being randomly assigned to groups of four...

News reports and communication are inherently constrained by space, time, and attention. As a result, news sources often condition the decision of whether to share a piece of information on the similarity between the signal and the prior belief of the audience, which generates a sample selection...
