Abstract:
This paper studies a principal-agent relationship in which either the principal or a supervisor can monitor the agent's hidden action by the use of identical monitoring technologies. The author assumes that signals are private information and commitment to monitoring is not possible. He shows that delegation of monitoring is profitable. With delegation the principal can better regulate incentives (incentive effect) and commit to a broader range of wage structures (commitment effect). The author introduces collusion to find an endogenous bound on rewards and shows that collusion limits the commitment effect but, due to the incentive effect, delegation remains profitable.
