    摘要This paper investigates how firm-level unsolved uncertainty after corporate earnings release affect management voluntary disclosure policies. Using large samples of quarterly management guidance and voluntary 8-K items as proxy for voluntary disclosures and patterns of change in implied volatilities around EAD as a proxy for unsolved uncertainty, we document a robust positive relation between unsolved uncertainty and forecast frequency, informativeness, bad news disclosures, and timeliness of disclosures. Consistent with the notion that managers consider the disclosures benefits and costs, cross-sectional evidence suggests that such relationship is more pronouncement when managers have information advantages, when they are more likely to notice option market information, and when firms' earnings announcement attract more market attention. Our results show the importance of second-order information from option market and provide new evidence for managerial learning perspective.
