In experiments which measure subjects' beliefs, both beliefs about others' behavior and beliefs about others' beliefs, are often correlated with a subject's own choices. Such phenomena have been interpreted as evidence of a causal relationship between beliefs and behavior. An alternative...

Empirically, social dilemma under information asymmetry are often much less pronounced than theory predicts. Traders experience a winner's curse and maintain efficiency enhancing exchange of commodities when theory predicts none. Especially under competition, cursed parties undergo severe losses...

Charitable donations are often made through intermediaries who can fund themselves from these same donations. Donors who purchase charitable output through an intermediary incur a principal-agent problem with unobservable prices. We compare charitable giving in an experiment with and without...

This Monte-Carlo study investigates sensitivity of the Wilcoxon signed rank test to certain assumption violations in small samples. Emphasis is put on within-sample-dependence, between-sample dependence, and the presence of ties. Our results show that both assumption violations induce severe...

Anecdotal, empirical, and experimental evidence suggests that offering extrinsic rewards for certain activities can reduce people's willingness to engage in those activities voluntarily. We propose a simple rationale for this 'crowding out' phenomenon, using standard economic arguments. The...

We report an experiment on the Probabilistic Serial (PS) mechanism for allocating indivisible goods. The PS mechanism, a recently discovered alternative to the widely used Random Serial Dictatorship mechanism, has attractive fairness and efficiency properties if people report their preferences...
