讲座主题：董事网络中心度和系统性风险

摘要：We find that the boardroom centrality formed by sharing directors across firms can significantly increase firms’ systematic risk estimated by the beta coefficient of the CAPM model/FF model. The results are robust after addressing the endogenous issues with the two-stage least square estimation with the instrumental variables based on exogenous changes in directors’ boardship outside the focal firm. Such positive effects are stronger when boardroom centrality is formed by inside executive directors, more experienced directors, and directors who also sit on other large firms, stock market index included firms. We also find that boardroom centrality can increase corporate policy and fundamental correlations between the appointing firm and other firms in the markets. Final, board centrality is positively associated with firms’ cost of equity and negatively related to firm value after controlling firms’ expected future cash flows. Taken together, the findings of this paper highlight the roles of corporate leaders in affecting firms’ systematic risk and cost of equity, which have been highly neglected by the literature.
