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 ran a field experiment to investigate whether nudge policies, consisting in behavioural insight messaging, help to improve performance in financial trading. Our experiment involved students enrolled in a financial trading course in an Italian University who were invited to trade on Borsa...

Fungibility of money is a central principle in economics. It implies that any unit of money is substitutable for another and that the composition of income is irrelevant for consumption. We find in a field experiment that even in a simple, incentivized setup many subjects do not treat money as...

This paper takes advantage of a natural experiment to examine the relationship between the price and saliency of health services. A large employer e-mailed individually-targeted health education encouraging high-value care to high-risk employees. Weeks before the program launched, a company...

Standard economic analysis assumes that people make choices that maximize their utility. Yet both popular discourse and other fields assume that people sometimes fail to make optimal choices and thus adversely affect their own happiness. Most social sciences thus frequently describe some...

The literature on happiness shows that there are many factors that influence a person s happiness. Extending previous studies, we investigate the role of the freedom of choice as a key contributing construct in influencing a person s happiness. We define two hypothetical sub-constructs for the...

More than two of every five students who enrolled in college in 2007 failed to graduate by 2013. Peer tutoring services offer one approach toward improving learning outcomes in higher education. We conducted a randomized controlled experiment designed to increase take-up of university tutoring...

We theoretically show that agents with loss-averse preferences facing a decision to receive a bad financial payoff if they report honestly or to receive a better financial payoff if they report dishonestly are more likely to lie to avoid receiving the low payoff the lower the ex-ante probability...
