The Effect Of Voluntarily Disclosing An Earnings Surprise On Management Operating Decisions, Jonathan Gay

Theses and Dissertations

Prior research extensively examines the external implications of voluntarily disclosing an earnings surprise, yet the internal implications remain understudied. Using two experiments, I examine whether the preemptive voluntary disclosure of an earnings surprise influences management operating decisions. Drawing upon mental accounting and the realization effect, I predict that managers are more likely to make inefficient operating decisions when an earnings surprise is expected and that a quantitative, but not qualitative, voluntary disclosure will mitigate this value-sacrificing behavior. I find that managers are more likely to make inefficient operating decisions when a negative, but not a positive, earnings surprise is expected …
