The incentive intensity of rewards (the individual. marginal gains in pay t
riggered by increased performance) has been linked to higher effort and the
attraction of talent. Determinants of incentive intensity for individual r
ewards have been widely examined, but determinants of incentive intensity f
or group rewards remain unexplored. We used agency theory to test such dete
rminants in 663 group-based pay plans. Incentive intensity was higher when
groups were small, when plans did not need to measure quality, and when man
agement participation was high. Plans embedded in small firms and plans wit
h longevity had higher incentive intensity.
