Abstract

The belief that bank capital helps improve stability takes for granted the idea that increases in capital are an incentive to reduce risk-taking because bank owners would have more to lose (skin-in-the-game) if their banks fail. Nevertheless, given the higher cost of capital as compared to debt, it is also possible that increases in capital would lead to higher risk-taking due to the need for banks to boost their returns. In light of these contradictory possibilities, we exploit exogenous variations of capital to empirically investigate the actual effects of capital on risk-taking. Our analyses based on a sample of nearly 1900 US Banking Holding Companies in the 1990–2020 period indicate that increasing capital actually leads to higher risk-taking, which contradicts the skin-in-the-game hypothesis. We show evidence that this relationship could be explained by the consequent increase in funding costs that creates pressure for better returns, which is normally achieved by means of taking higher risk. Our main findings are robust to a number of alternative model and sample specifications.

银行的风险承担:"亲身参与 "真的重要吗?
摘要 银行资本有助于提高稳定性的观点认为,增加资本是减少风险承担的一种激励措施,因为如果银行倒闭,银行所有者会有更大的损失(利益受损),这是理所当然的。然而,与债务相比,资本成本较高,因此,由于银行需要提高收益,增加资本也有可能导致更高的风险承担。鉴于这些相互矛盾的可能性,我们利用资本的外生变化来实证研究资本对风险承担的实际影响。我们基于 1990-2020 年间近 1900 家美国银行控股公司的样本进行的分析表明,增加资本实际上会导致更高的风险承担,这与 "游戏规则 "假说相矛盾。我们有证据表明,这种关系的原因可能是融资成本随之增加,从而产生了获得更高回报的压力,而这通常是通过承担更高风险来实现的。我们的主要发现对一些替代模型和样本规格都是稳健的。
