Collusion in Hierarchical Agency e-bog

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. Abstract: We study a model where shareholders can use auditors' reports to contract with a privately informed manager but the manager can bribe the auditors to manipulate their reports. Such auditors are useful if they have good information and the liability of the manager is high.<br><br>In the optimal contract under collusion, even with unbounded punishments and costless auditing, production does not reach its optimal level. Raising the punishment for the manager raises the bribe he is willing to offer the auditor raising the cost of preventing collusion. When liability grows without bound and part of the punishment is non-transferable maximum deterrence will not be optimal.<br><br>To model cross-checking mechanisms, we distinguish internal (costless but may collude with the manager) from external (costly but never collude) auditors. We prove that the optimal contract might specify random external audits. We consider a self-interested external auditor and find that the optimal contract is unchanged<br><br>Finally, we present a model where allowing collusion is the optimal strategy for the principal.
