The beneficial effect of common ownership: Evidence from bank liquidity creation
研究发现银行共同所有权越高，流动性创造越多（3.56%-4.54%），主要通过提高风险吸收能力、信息披露质量和长期持股等渠道实现，对银行监管和投资者有参考价值。
We argue a positive association between common ownership and liquidity creation because common ownership increases risk-absorption capacity through higher profit margins, greater equity capital, and improved disclosure quality. Accordingly, we find solid evidence that banks with greater common ownership create 3.56%–4.54% more liquidity. The beneficial effect on liquidity creation is dominant for banks with high risk-absorption capacities, enhanced disclosure quality, low competition, greater long-term shareholdings, and low performance-sensitive managerial incentives, substantiating our theoretical conjectures and establishing five significant channels. Finally, we show that banks have incentive to create more liquidity when they have significant co-ownerships among themselves. Our main findings remain robust to multiple proxies, alternative specifications, and three methods to address endogeneity concerns – difference-in-differences based on the Blackrock–Barclays Global Investors merger in 2009, two-stage least squares analysis with instrumental variables based on Russell 2000 index inclusion, and propensity score matching.
