Audit contracts and reputation

This paper characterizes the contractual relationship between an external auditor and a manager of a client firm when the incentives for both agents are implicit as in the career concerns framework. The main result is that the earning management and the audit effort are decreasing over time because the incentives to build a reputation also decline for both agents in spite of a managers first mover advantage. This suggests that the audit effort should be higher when the auditor is an emerging firm and the future employment opportunities for the client firm´s manager are larger.
