A long-recognized phenomenon in capital markets is the underinvestment in foreign equity securities, known as equity home bias. Our study examines the effect of board independence on the firm's ability to attract foreign equity capital. After accounting for potential endogeneity, we document that U.S. and non-U.S. foreign investors exhibit a strong preference for firms with more independent corporate boards. Further, our analysis indicates that the positive relation between board independence and foreign ownership is significantly stronger in countries with less developed legal institutions and poor external protection of investor rights. We suggest that it is in these countries that firm-determined characteristics such as independent boards can be most beneficial in attracting capital. We also find that institutional investors are more responsive to the impact of independent corporate boards than are other types of investors.

We provide the first comprehensive and robust evidence on the relationship between board independence and firm performance in China. We find that independent directors have an overall positive effect on firm operating performance in China. Our findings are robust to a battery of tests, including endogeneity checks using instrumental variables, the dynamic generalized method of moments estimator, and the difference-in-differences method. The positive relationship between board independence and firm performance is stronger in government-controlled firms and in firms with lower information acquisition costs. We also document that Chinese independent directors play an important role in constraining insider self-dealing and improving investment efficiency.
