Summary
Group incentive systems have to overcome the free rider or 1/N problem, which gives workers an incentive to shirk, if they are to succeed. This paper uses new questions on responses to shirking from the General Social Survey and a special NBER survey of workers at over 300 worksites in 14 companies that have some form of group incentive pay to examine how well workers can monitor their peers and what they do when the peers are not working up to speed.
