Abstract
This paper studies how the human capital embedded in rank-and-file employees affects firms’ stock price crash risk. Employing a unique setting in China where we measure human capital using employee information at the firm level, we show that human capital quality improves firms’ internal information environments, curbs bad-news hoarding and overinvestment, leading to lower stock price crash risk. The findings are robust to instrumental variable regressions. Our study highlights the internal informational role of human capital and sheds light on its implications for capital markets and outside investors. Therefore, we contribute to the literature on the interaction between non-shareholding stakeholders and shareholders.

Notes
This includes an employee’s creativity, useful knowledge in specific areas, work skills in a particular field, social skills, personality, and work ethic.
The RESSET database is a data platform that provides professional services for model testing and investment research. For more details, please refer to http://www.resset.cn/databases.
Call et al. (2017) show that firms headquartered in areas whose population has higher education levels are associated with better financial reporting outcomes. We directly measure the education level of employees at each firm and show that it is negatively related to stock price crash risk. We therefore have a more accurate measure and extend the effect of education to the capital market.
Please note that some observations are dropped due to missing values of employee compensation.
We also construct the demeaned HUMCAP by subtracting the mean level of HUMCAP of the same city from the firm level to test our hypothesis, and we find robust results.
We do not employ the firm fixed-effects model for the main analysis because employee quality does not vary significantly within firms. In such cases where the regressor does not present much time-series variation, firm fixed-effect model results will be unreliable (Zhou, 2001).
Please note that PROVEDU only provincial data are available. while for other demographic controls city-level data are available.
The ten cities are Qiqihar, Maoming, Putian, Xianyang, Guigang, Shangqiu, Weifang, Zhongshan, Jieyang, and Zhoukou, which are all third-tier cities in China.
We use the V–V test because our measurement of overinvestment (OVERINVEST) is a binary variable, and the Sobel test is only appropriate when the mediator is continuous.
The internal control quality index is obtained from the DIB internal control database, which has been widely used in Chinese studies of internal control quality (e.g., Liu et al., 2017). The index is calculated based on the firm’s internal environment, risk assessment, internal control activities, and internal monitoring.
Gallemore and Labro (2015) employ two additional proxies for internal information quality: management forecast accuracy and restatements caused by unintentional errors. We do not use management forecast accuracy because we believe it is confounded with managers’ unethical incentives related to bad-news hoarding. In addition, we do not use restatements caused by unintentional errors because we cannot disentangle the restatements caused by unintentional errors from those caused by intentional errors in the Chinese setting.
