This study examines whether religiosity at the county level is associated with future stock price crash risk. We find robust evidence that firms headquartered in counties with higher levels of religiosity exhibit lower levels of future stock price crash risk. This finding is consistent with the view that religion, as a set of social norms, helps to curb bad-news-hoarding activities by managers. Our evidence further shows that the negative relation between religiosity and future crash risk is stronger for riskier firms and for firms with weaker governance mechanisms measured by shareholder takeover rights and dedicated institutional ownership.

Using a large sample of U.S. public firms, we find robust evidence that short interest is positively related to one-year ahead stock price crash risk. The evidence is consistent with the view that short sellers are able to detect bad news hoarding by managers. Additional findings show that the positive relation between short interest and future crash risk is more salient for firms with weak governance mechanisms, excessive risk-taking behavior, and high information asymmetry between managers and shareholders. Empirical support is provided showing that the relation between short interest and crash risk is driven by bad news hoarding.

Prior research documents that information transmitted via director networks affects firms' policies and real economic activities. Given a manager's potential monopoly over firm information, it is important to analyze whether information transmission through director social networks undermines the manager's control. Specifically, we explore whether information flow through director networks influences managers' ability to hoard bad news. We predict and find that the extent of external connections of the board of directors is negatively associated with future stock price crash risk. Additional analysis implies that this evidence is driven by firms with more powerful executives, with weaker auditor monitoring, or subject to strong investor protection, and by directors with greater monitoring incentives or responsibilities and directors with less firm‐specific knowledge. Collectively, our research lends empirical support for the monitoring view under which better‐informed directors narrow the scope for bad news hoarding evident in stock price crash risk. In another series of tests, we fail to find evidence consistent with the information leakage view under which directors pass sensitive firm‐specific information to connections that trade on the information before its public release. Other analysis helps dispel the concern that the endogenous match between directors and companies is spuriously responsible for our core results. Our empirical findings have important implications on how social networks affect the proper functioning of capital markets.

We analyze whether tough IRS monitoring generates a positive externality by constraining managers' bad news hoarding activities. Supporting this prediction, we find a negative relation between the threat of an IRS audit and stock price crash risk. Our evidence is consistent with recent theory that outside investors learn more about firms when tax enforcement is stricter. Additionally, path analysis suggests that the monitoring channel (direct path) plays a critical role in shaping crash risk relative to information asymmetry channels of tax planning and accruals manipulation (indirect paths). Consistent with other predictions, we find that the monitoring role of IRS audits intensifies when firms experience worse agency conflicts stemming from CEO power and incentives. Collectively, our research implies that external monitoring by tax authorities protects shareholders against managers suppressing negative firm-specific information that engenders stock price crash risk, particularly when CEOs have wider scope and stronger incentives to hoard bad news.
