Suggested contributions, membership categories, and discrete, incremental thank you gifts are devices often used by benevolent associations that provide public goods. Such devices focus donations at discrete levels, thereby effectively limiting the donors' freedom to give. We study the effects...

We introduce threshold uncertainty, a la Nitzan and Romano (1990), into a private-values model of voluntary provision of a discrete public good. Players are allowed to make any level of contribution toward funding the good, which is provided only if the cost threshold is reached. Otherwise,...

We analyze a symmetric Bayesian game in which two players individually contribute to fund a discrete public good; contributions are refunded if they do not meet a threshold set by the seller of the good. We provide a general characterization of symmetric equilibrium strategies that are continuous...
