Growing calls for expanded disclosure on managerial stewardship raise important questions about how finer (i.e., disaggregated) reporting, when paired with discretion over classification, will influence managerial behavior. To study this question, we develop an investment game in which, if the investor chooses to invest, the manager privately observes production costs, chooses their personal pay, and provides a cost report in one of three reporting regimes: aggregated, disaggregated without discretion, or disaggregated with discretion. In Experiment 1, as predicted, managers report lower personal pay under both disaggregated regimes than what they consume under the aggregated regime. Yet, when disaggregated reports allow for discretion, managers misclassify personal pay as production costs to such an extent that their actual consumption is no different than in the aggregated condition. In Experiment 2, we allow managers to choose either an aggregated report or a disaggregated report with discretion. We find that, rather than remaining silent, the vast majority of managers still prefer the opportunity to explicitly report on their pay so that they can use their reporting discretion to appear trustworthy, despite not actually being so. In summary, our evidence suggests a strong weight of preferences for appearing trustworthy in the managers’ utility function, a much lower weight for actually being trustworthy, and little evidence that preferences for being honest are strong enough for discretionary disaggregated reporting to curb agency costs. In other words, whether disaggregation can reduce agency costs will depend on managers’ reporting discretion. Our findings have important implications for control system designers, financial and sustainability accounting standard setters, and regulators
