We introduce reward money into the provision point mechanism with refunds. Reward money is distributed among the contributors in proportion to their contributions only when the provision point is not reached. In environments without aggregate uncertainty, the provision point is always reached in...

We consider a two group contest over a group specific public good where each member of a group has a different benefit from the good. Our model can be interpreted in two ways: Each of the players has a non-linear investment cost in the contest, or alternatively, the returns to effort are...

We consider a two group contest over a group specific public good comparing two situations: (i) when all players act independently; and (ii) when the players of each group cooperate. This comparison leads us to the conclusion that it is possible for one group to contribute more (and have a...

This paper examines whether and how cheap talk communication can facilitate within-group coordination when two unequal sized groups compete for a prize that is shared equally among members of the winning group, regardless of their (costly) contributions to the group's success. We find that...

This paper analyzes the private provision of public goods where consumers interact within a fixed network structure and may benefit only from their direct neighbors' provisions. We present a proof for existence and uniqueness of a Nash equilibrium with general best-reply functions. Our...

This paper investigates the private provision of public goods in segregated societies. While most research agrees that segregation undermines public provision, the findings are mixed for private provision: social interactions, being strong within groups and limited across groups, may either...

This paper studies the incentives for interim voluntary disclosure of verifiable information in probabilistic all-pay contests. Provided that the contest is uniformly asymmetric, full revelation is the unique perfect Bayesian equilibrium outcome. This is so because the weakest type of the...

A core allocation of a complete information economy can be characterized as one that would not be unanimously rejected in favor of another feasible alternative by any coalition. We use this test of coalitional voting in an incomplete information environment to formalize a notion of resilience....

Beliefs in signals that reveal lies or truths are widespread. These signals may lead to a truth or lie detection bias if the probability that such a signal is perceived by the receiver is contingent on the truth value of the sender's message. Such detection biases are analyzed theoretically in a...

Suppose that the goals of a society can be summarized in a social choice rule, i.e., a mapping from relevant underlying parameters to final outcomes. Typically, the underlying parameters (e.g., individual preferences) are private information to the agents in society. The implementation problem...
