This paper presents evidence from a laboratory experiment comparing different incentive mechanisms for team work: centralized (target-based and team tournament) and decentralized (peer-pressure), or revenue sharing, which constitutes our baseline treatment. We observe free-riding in the baseline treatment, albeit not as severe as theoretically-predicted. Peer pressure partly limits free-riding but is costly for workers. Target-based schemes lead to near-Pareto levels of effort and high firms’ profits but provide relatively lower workers’ payoffs. Finally, team tournaments generate high efforts but also high payoff inequalities among workers. JEL Codes: J33, C92.
