Audits, Reputation, and Repeated Interaction in a Capital Budgeting Setting

This experimental study investigates the use of audits as a control instrument in capital budgeting processes and factors that contribute to audit efficiency (or inefficiency) in a repeated relationship. We disentangle reputational aspects of superiors and subordinates from an increased social content in repeated relationships. In settings where subjects face new counterparts every round, we find that reputational aspects strongly affect the superiors' and subordinates' behavior. This leads to a decrease in slack and an increase in the superior payoff. However, in a repeated relationship with an increased level of social content, these benefits are no longer present. In fact, the subordinates' ability to retaliate against their superior for prior punishments in the repeated setting by reporting more slack in later rounds has negative effects on the use of audits and decreases audit efficiency. These findings imply that, in repeated relationships, social factors play an important role and might impair the disciplining effects of audits.
