We examine the voluntary disclosure practices of family firms. We find that, compared to nonfamily firms, family firms provide fewer earnings forecasts and conference calls, but more earnings warnings. Whereas the former is consistent with family owners having a longer investment horizon, better monitoring of management, and lower information asymmetry between owners and managers, the higher likelihood of earnings warnings is consistent with family owners having greater litigation and reputation cost concerns. We also document that family ownership dominates nonfamily insider ownership and concentrated institutional ownership in explaining the likelihood of voluntary disclosure. Using alternative proxies for the founding family's presence in the firm leads to similar results.

We examine whether analysts' earnings forecasts are more accurate when they also issue cash flow forecasts. We find that (i) analysts' earnings forecasts issued together with cash flow forecasts are more accurate than those not accompanied by cash flow forecasts, and (ii) analysts' earnings forecasts reflect a better understanding of the implications of current earnings for future earnings when they are accompanied by cash flow forecasts. These results are consistent with analysts adopting a more structured and disciplined approach to forecasting earnings when they also issue cash flow forecasts. Finally, we find that more accurate cash flow forecasts decrease the likelihood of analysts being fired, suggesting that cash flow forecast accuracy is relevant to analysts' career outcomes.

Interleukin-6 is an inflammatory cytokine with wide-ranging biological effects. It has been widely demonstrated that neuroinflammation plays a critical role in the development of pathological pain. Recently, various pathological pain models have shown elevated expression levels of interleukin-6 and its receptor in the spinal cord and dorsal root ganglia. Additionally, the administration of interleukin-6 could cause mechanical allodynia and thermal hyperalgesia, and an intrathecal injection of anti-interleukin-6 neutralizing antibody alleviated these pain-related behaviors. These studies indicated a pivotal role of interleukin-6 in pathological pain. In this review, we summarize the recent progress in understanding the roles and mechanisms of interleukin-6 in mediating pathological pain associated with bone cancer, peripheral nerve injury, spinal cord injury, chemotherapy-induced peripheral neuropathy, complete Freund’s adjuvant injection, and carrageenan injection. Understanding and regulating interleukin-6 could be an interesting lead to novel therapeutic strategies for pathological pain.

We construct a new, parsimonious, measure of disclosure quality—disaggregation quality (DQ)—and offer validation tests. DQ captures the level of disaggregation of accounting data through a count of nonmissing Compustat line items, and reflects the extent of details in firms’ annual reports. Conceptually, DQ differs from existing disclosure measures in that it captures the “fineness” of data and is based on a comprehensive set of accounting line items in annual reports. Unlike existing measures, which are usually applicable for a subset of firms or are based on a subset of information items, DQ can be generated for the universe of Compustat industrial firms. We conduct three sets of validation tests by examining DQ's association with variables predicted by prior literature to be associated with information quality. DQ is negatively (positively) associated with analyst forecast dispersion (accuracy) and negatively associated with bid‐ask spreads and cost of equity. These associations continue to hold after we control for firm fundamentals. Taken together, results from this battery of validation tests are consistent with our measure capturing disclosure quality.

This study examines recent regulatory and practitioner concerns that managers provide more (less) information to analysts with more (less) favorable stock recommendations. We examine the relative forecast accuracy of analysts before and after a recommendation issuance under the assumption that increases (decreases) in management-provided information will increase (decrease) analysts' relative forecast accuracy. We find that analysts issuing more favorable recommendations experience a greater increase in their relative forecast accuracy compared with analysts with less favorable recommendations. Additional tests on the change in frequency with which analysts issue forecasts independent of or in conjunction with other analysts after their recommendation change yield corroborating results. In addition, we find that the greater increase in relative accuracy for analysts with more favorable recommendations exists prior to the passage of Regulation FD but not after. The combined results are consistent with analysts receiving relatively more management-provided information following the issuance of more favorable recommendations.
