A common feature of the literature on the evolution of preferences is that evolution favors nonmaterialistic preferences only if preference types are observable at least to some degree. We argue that this result is due to the assumption that in each state of the evolutionary dynamics some...

We study theoretically and experimentally decision making under uncertainty in a social environment. We introduce an interdependent preferences model that assumes that the decision maker evaluates monetary outcomes in relation both with his individual and his social reference point. In the...

Adjudication errors in contests have a dual nature: they imply at the same time the unjust exclusion of a meritorious candidate (exclusion error) and the unjust inclusion of a non-meritorious one (inclusion error). We study theoretically and experimentally the effects of adjudication errors on...

When Legislators award amnesties to ‘low-rank' criminals cooperating with the justice, top criminals may capture public officials to avoid being sanctioned. Optimal policies should anticipate this danger and fight it back by granting amnesties not only to low-rank criminals, but also to...

We study experimentally whether heterogeneity of behavior in the Centipede game can be interpreted as the result of a learning process of individuals with different preference types (more and less pro-social) and coarse information regarding the opponent's past behavior. We manipulate the...
