We use subjects’ actions in modified dictator games to perform a within-subject classification of individuals into four different types of interdependent preferences: Selfish, Social Welfare maximizers, Inequity Averse and Competitive. We elicit beliefs about other subjects’ actions in the...

We study how gender differences in performance under competition are affected by the provision of information regarding rival’s gender and/or differences in relative ability. In a laboratory experiment, we use two tasks that differ regarding perceptions about which gender outperforms the...

Having access to unique data on the universe of users of all public libraries in Barcelona, we test the effect of sending email messages with dierent contents.

This paper studies the effect of providing relative performance feedback information on individual performance and on individual affective response, when agents are rewarded according to their absolute performance. In a laboratory set-up, agents perform a real effort task and when receiving...

We study the effect of providing relative performance feedback information on performance, when individuals are rewarded according to their absolute performance. A natural experiment that took place in a high school offers an unusual opportunity to test this effect in a real-effort setting. For...
