We study a continuous-time problem of optimal public good contribution under uncertainty for an economy with a finite number of agents. Each agent can allocate his wealth between private consumption and repeated but irreversible contributions to increase the stock of some public good. We study...

We examine the impact of one-time threats of expulsion and punishment on voluntary contributions in a public goods game. Participants played in 15-round sessions where they were allowed to vote to remove other subjects only after round 5 and in one design also voted whether to punish the...

The restart effect occurs in linear voluntary contribution mechanism (VCM) experiments when there is an upward pulse in contributions to the group account following a stoppage and then restarting of the VCM experiment. Although the restart effect is a well-known empirical regularity little...

We show that efficient anonymous incentive compatible (dominant strategy) mechanisms for public goods eliminate externalities, i.e., each individual is unable to change the welfare of anyone else. The characterization is used to derive existence and non-existence results for models with a finite...

We study mechanism design problems in quasi-linear environments where the envelope theorem and revenue equivalence principle fail due to non-convex and non-differentiable valuations. We obtain a characterization of incentive compatibility based on the Mirrlees representation of the indirect...

This research is inspired by in-kind donations that have the capacity to increase the marginal benefit (productivity) in provision of public goods, for example by providing critical infrastructure that increases the productivity of resources utilized by local public good providers. We provide...

The provision of public goods often benefits a larger group than those who actively provide the public good. In an experimental setting, this paper addresses institutional arrangements between subjects who can provide a public good (insiders) and subjects who benefit from the public good but...

We consider collective decisions made by agents whose preferences and power depend on past events and decisions. Faced with an ineffcient equilibrium and an opportunity to commit to a policy, can the agents reach an agreement on such a policy? Under an intuitive condition linking power...

In this paper, we analyze how kinship among family members affects intergenerational cooperation in a public good game. 165 individuals from 55 families, comprising three generations (youths, parents, and grandparents), play a public good game in three different treatments: one in which three...
