诚信,既是道德,也是领导力.本文以言行一致表征诚信,以2010至2019年A股上市公司为样本,实证检验上市公司CEO言行一致对公司股价崩盘风险的影响.研究发现,CEO言行一致显著降低了公司股价崩盘风险.在理论推导和现实画像揭示子公司负责人是坏消息隐藏行为主体之一的基础上,机制检验发现,CEO言行一致通过约束自利动机、弥补制度缺陷、形成德行垂范等治理机制来抑制子公司负责人坏消息隐藏行为,进而降低公司股价崩盘风险,实证支持CEO言行一致的领导力理论假说.此外,子公司负责人坏消息隐藏行为会对CEO职业生涯造成不利影响,则揭示了 CEO言行一致的动因.进一步研究发现,当经营分权程度较高、子公司负责人任职地区社会信用水平较低时,CEO言行一致对公司股价的稳定效应更显著.本文拓展了公司股价崩盘风险影响因素及经理层代理问题治理研究,对推进社会信用体系建设具有参考价值.
CEO Behavioral Integrity and Stock Price Crash Risk:Based on the Mechanism Test of Bad News Hoarding by the Head of Subsidiaries
Integrity is both a moral principle and a leadership quality.This study conceptualizes integrity as behavioral integrity(BI)and empirically investigates the impact of CEO BI on the stock price crash risk of listed firms.The results reveal that CEO BI significantly mitigates the stock price crash risk.Based on the theoretical deductions and practical portrait that identify the head of subsidiaries as one of the main actors engaging in bad news hoard-ing behavior,the mechanism test indicates that CEO BI suppresses the bad news hoarding behavior by the head of subsidiaries through the governance mechanisms of constraining self-interest motivation,remedying institutional deficiencies and leading by example,ultimately reducing the stock price crash risk.The bad news hoarding behavior by the head of subsidiaries can adversely affect the CEO's career,revealing the motivation behind the CEO BI.Addi-tional analysis shows that the stabilizing effect of CEO BI on the stock price is more pronounced in firms with higher level of business decentralization and lower level of social credit in the regions where the head of subsidiaries operates.The findings remain robust after endogeneity test.This study expands the research on the factors influencing the stock price crash risk and the governance on the managerial agency problem,and also provides implications for pro-moting the social credit system.
