RT Monograph SR 00 A1 Angelucci, Charles A1 Russo, Antonio T1 Moral Hazard in Hierarchies and Soft Information YR 2012 FD 2012-10 VO 12-343 K1 collusion K1 extortion K1 delegation K1 mechanism design AB We investigate the scope for supervisory activities in organizations in which information is non-verifiable and opportunism severe. A principal-supervisor-agent hierarchy is considered. Side-contracts between supervisor and agent may be reached both before and after the agent has chosen his hidden action. We find that the supervisor is useful if and only if appointed before the agent has chosen his action. We also show that delegation of payroll authority is suboptimal. Finally, some insights concerning the optimal design of verification activities are provided: when information is non-verifiable, the supervisor should be employed as a monitor rather than as an auditor.
