I show how improper conditioning of beliefs can reduce contribution in public goods environments with interdependent values. I consider a simple model of a binary, excludable public good. In equilibrium, provision of the public good is good news about its value. Naive players who condition...

Recent studies suggest that cooperative decision-making in one-shot interactions is a history-dependent dynamic process: promoting intuition versus deliberation has typically a positive effect on cooperation (dynamism) among people living in a cooperative setting and with no previous experience...

We study the choice of a principal to either delegate a decision to a group of careerist experts, or to consult them individually and keep the decision-making power. Our model predicts a trade-off between information acquisition and information aggregation. On the one hand, the expected benefit...

We conduct multi-person one-shot ultimatum games that reflect important aspects of collective bargaining. In all treatments a proposer has to divide a pie among herself and two groups of three recipients each. She cannot discriminate within, but across groups. A committee with representatives...

This paper examines behavior (the oretically and experimentally) in a two-stage group contest where the fi rst stage comprises of intra - group contests, followed by an inter-group contest in the second stage. Rewards accrue only to the members of the winning group in the inter-group contest,...

Is free-riding in teams reduced when one member receives a signal on his colleagueís performance? And how does free-riding depend on the signal's type? We address these questions in experimental teams in which two agents sequentially exert effort to contribute to the team output. We vary the...

This paper presents a laboratory experiment to measure the effect of group membership on individual behavior in modified dictator games. The results suggest that this effect is influenced by the degree of group membership saliency. A within-subject design is employed: in stage 1, each subject...
