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 reach a threshold set by the seller of the good. We characterize the distributions of players' private values that can support a symmetric equilibrium in continuous piecewise-linear strategies, and we calculate these strategies. Allowing the seller to charge an entry fee before players make their private contributions, we show these piecewise-linear equilibrium strategies maximize the seller's expected profit over all incentive compatible selling mechanisms.

AbstractWe consider a preemption game between competing groups; firms lobbying individually for their groups' interests provide an empirical example. Among symmetric groups, the first firm to take action bears an (unobserved) cost and wins the prize on behalf of its group. In equilibrium, the firm with the lowest cost takes action, but with delay. More competition and a smaller ratio of costs to benefits reduce delay. Firms in larger groups wait longer, but group action can occur earlier, as the probability of a low‐cost firm is higher. Asymmetries in group size or strength of externalities also matter.
