It's your turn: experiments with three-player public good games

We report results from experiments designed to investigate the prevalence of turn-taking in three-person finitely repeated threshold public good games without communication. Individuals can each make a discrete contribution. If the number of contributors is at least equal to the threshold, a public benefit accrues to all group members. Players take turns to provide the public good each round when the endowments are homogeneous. When the turn-taking path is at odds with efficiency or under private information of endowments, players seldom engage in taking turns. An endogenous-move protocol limits the frequency of mis-coordinated outcomes every round.
