公司治理、资本监管与银行风险承担

选取2007-2017年中国25家上市银行数据,采用面板回归模型对公司治理与资本监管对银行风险承担的影响进行实证分析。研究表明：股权集中度与银行风险承担之间呈正U型关系,较低的股权集中度会降低银行风险资产配置权重,股权集中度的提升会加大银行风险承担。董事会规模会促进银行风险承担,董事会规模过大将平滑单个董事表决权,导致董事会控制效率下降而引发银行经营决策频繁变动,由此加大银行风险承担。资本监管会抑制银行风险承担,资本监管的趋严促使银行减持风险资产进行资本补充;资本监管对股份制银行、国有大型银行与城农商银行风险承担的影响力度依次递减。货币供给增速的放缓将降低银行存款吸收能力,由此加大银行流动性风险,货币供给对银行信贷存在制约效应;经济增速的下调将降低企业盈利能力,由此加大银行风险承担,银行存在顺周期放贷倾向。     

Fintech,macroprudential policies and bank risk: Evidence from China

We explore the relationship between fintech, macroprudential policies, and commercial bank risk-taking. Based on system generalized method of moment modeling on a panel data of 114 commercial banks in China from 2013 to 2020, results show that there are functional differences in the impact of fintech on bank risk-taking. Payment and settlement technology (PST), capital raising technology (CRT) and investment management technology (IMT) are positively correlated with bank risk-taking. In contrast, market facility technology (MFT) negatively correlates with bank risk-taking. We also find that macroprudential policies weaken the promotion effect of CRT on bank risk-taking and strengthen the inhibition effect of MFT on bank risk-taking while having no significant moderating effect on PST and bank risk, IMT and bank risk. Further, the micro characteristics of banks (capital adequacy ratio, asset scale, liquidity level) affects the moderating strength of macroprudential policies. Various robustness tests confirm our conclusions.     

What drives risk-taking incentives embedded in bank executive compensation? Some international evidence

This paper analyzes the country determinants of risk-taking incentives embedded in bank executive compensation using hand-collected international panel data on 135 publicly-traded banks in 26 countries. We exploit time-series changes in investor protection within a country and confirm that stronger protection leads to a higher vega. Moreover, the positive effect on vega is higher in countries where stronger bank competition and more extensive safety nets increase bank shareholders' risk-taking incentives. Our analysis controls for changes in bank regulation, systemic banking crises, and government bailouts. The results are robust to alternative specification models, alternative proxies for country determinants, and remain when we apply a more traditional cross-sectional analysis.     

Bank dividends,risk, and regulatory regimes

This paper investigates the relation between bank dividends and bank risk over the period 1984–2011, and assesses the existence of risk-taking and risk-shifting in the US commercial banking sector subject to regulatory regime changes. The introduction of PCA in 1992 and TARP in 2008 constitute significant regulatory regime changes, and provide the necessary framework to explore whether regime-dependent risk-shifting or risk-taking is present. We find strong evidence of risk-shifting and risk-taking over the post-PCA regime spanning the period 1992–2008. We interpret this evidence as indication of ineffectiveness of PCA in controlling risk-taking and risk-shifting. The finding of risk-taking just prior to the recent financial crisis suggests that risk-taking may be a factor contributing to this crisis. As risk-taking and risk-shifting are important aspects of bank behavior (Basel Committee on Banking Supervision, 2009), these results are of interest to bank regulators and important to Basel III.     

The conditioning role of performance on the bank risk-taking channel of monetary policy: Evidence from a multiple-tool regime

The study investigates how monetary policy affects bank risk-taking under a multiple-tool regime of Vietnam during 2007–2018. Particularly, we also consider the conditioning role of bank performance, broken down by bank profitability and cost efficiency, in this nexus. Using both dynamic and static panel models, we show that the liquidity injection initiated by the central bank’s asset purchases induces banks to take more risks, captured by the traditional Z-score and two alternative measures of credit risk. However, monetary policy easing through decreased interest rates is beneficial to the credit portfolio and financial stability of banks, which therefore challenges the functioning of the bank risk-taking channel. This startling result is robust across three different interest rate measures, including lending rates, refinance rates and rediscount rates. Further analysis reveals that our observed effects are alleviated for banks with higher performance — i.e., more profitable and efficient banks. This in-depth finding offers more insights into the “search for yield” incentive, based on the theory of information asymmetry and the two competing hypotheses of “bad management” and “cost skimping”.     

The role of strategic interactions in risk-taking behavior: A study from asset growth perspective

This study uses panel data on Vietnamese commercial banks from 2008 to 2018 in order to investigate the role of strategic interactions in determining bank risk-taking behavior by considering bank asset growth. The results suggest that aggressive competition is less favorable for banks striving for stability and that a high value of competitive strategy measure (as a proxy for strategic interactions) encourages risk-taking incentives. We also find that the distributional effects of strategic interaction on bank risk-taking because of asset growth reveal that the uncertainty in strategic-interaction-driven profits diminishes in banks with higher growth. This finding is consistent with the idea that when competition becomes more aggressive, bank restructuring should focus on increasing total assets by merging and acquiring small- and medium-sized banks to stabilize the banking sector. Furthermore, the results demonstrate that banks with low leverage or under regulatory pressure engage in more risk-taking. Therefore, policymakers may not implement a tighter capital requirement that contributes to a heightened level of risk. The results are robust to alternative measures of risk-taking and monetary policy stance as well as different econometric specifications.     

Spillover effects of banking systemic risk on firms in China: A financial cycle analysis

This paper investigates the spillover effects of banking sector risk on firms in China and explores the risk transmission channels from the perspective of financial cycle. We use the banking risk-taking and systemic risk as the proxies of financial booms and busts. Our study yields four main findings. First, the banking risk-taking reduces firm risk in financial booms. Higher financing costs and constraints, larger firm size and financing scale, and state ownership inhibit the spillover effects. Second, the banking systemic risk increases firm risk during financial busts. Higher financing costs and constraints, larger firm size and financing scale, and state ownership facilitate the spillover effects. Third, the magnitudes of banking risk spillovers vary across industries, and this effect is more pronounced in the manufacturing industry. Fourth, bank risk-taking affects firm risk differently through various channels in different leading periods. When leading 1 to 3quarters, banking risk-taking reduces firm risk, and channel variables inhibit the spillover effects. However, when leading 4 to 8 quarters, the rising bank risk-taking eventually increases firm risk, and channel variables amplify its spillover effects. Our study offers important policy implications for risk assessment and mitigation in the Chinese loan market.     

Strong boards,CEO power and bank risk-taking

This study examines the relevance of bank board structure on bank risk-taking. Using a sample of 212 large US bank holding companies over 1997–2004 (1534 observations), this study finds that strong bank boards (boards reflecting more of bank shareholders interest) particularly small and less restrictive boards positively affect bank risk-taking. In contrast, CEO power (CEO’s ability to control board decision) negatively affects bank risk-taking. These results are consistent with the bank contracting environment and robust to several proxies for bank risk-takings and different estimation techniques.

Interest rates and bank risk-taking

A recent line of research views the low interest-rate environment of the early to mid 2000s as an element that triggered increased risk-taking appetite of banks in search for yield. This paper uses approximately 18000 annual observations on euro area banks over the period 2001-2008 and presents strong empirical evidence that low-interest rates indeed increase bank risk-taking substantially. This result is robust across a number of different specifications that account, inter alia, for the potential endogeneity of interest rates and/or the dynamics of bank risk. Notably, among the banks of the large euro area countries this effect is less pronounced for French institutions, which held on average a relatively low level of risk assets. Finally, the distributional effects of interest rates on bank risk-taking due to individual bank characteristics reveal that the impact of interest rates on risk assets is diminished for banks with higher equity capital and is amplified for banks with higher off-balance sheet items.     

Fleeing entrepreneurs: Foreign residency right and corporate risk-taking

We use a unique sample of Chinese firms to investigate the impact of the foreign residency right (FRR) of a firm’s controlling person on corporate risk-taking. Our findings suggest that the controlling person’s FRR is negatively associated with corporate risk-taking, and the effect of FRR on risk-taking is significantly reduced by Operation Fox Hunt (a program for actively pursuing fled criminals) or when the foreign country has an extradition treaty with China. Our results are robust to tests for endogeneity, alternative metrics of FRR, and risk-taking. We also find that severe financial constraints and a decline in R&D activities are the channels through which FRR reduces corporate risk-taking. Additional analyses show that the effect of FRR on corporate risk-taking is more pronounced when (a) controlling persons hold foreign nationality, (b) controlling persons are powerful or older, or (c) the investors of the firm face greater information asymmetry.     

Politics,credit allocation and bank capital requirements

I develop a normative theory of political influence on bank lending and capital structure. Legislators want banks to make politically-favored loans that reduce bank profits but generate social or political benefits. The regulator uses asset-choice regulation and capital requirements to induce the lending desired by legislators. There are four main results. First, if regulators dislike bank fragility, then credit-allocation regulation should be accompanied by higher capital requirements. Second, banks will resist higher capital requirements, which will be lower when banks have more bargaining power. Third, when politics matters more in bank regulation, the banking sector is larger and more competitive, with higher capital requirements. Fourth, the optimal reporting mechanism, in which banks report their privately-known profitability and the regulator endogenously determines capital requirements and stringency of credit-allocation regulation in response, shows that political influence is stronger when banks are more profitable.     

What determines the profitability of banks? Evidence from Spain

This paper empirically analyses the factors that determine the profitability of Spanish banks for the period of 1999–2009. We conclude that the high bank profitability during these years is associated with a large percentage of loans in total assets, a high proportion of customer deposits, good efficiency and a low doubtful assets ratio. In addition, higher capital ratios also increase the bank’s return, but only when return on assets (ROA) is used as the profitability measure. We find no evidence of either economies or diseconomies of scale or scope in the Spanish banking sector. Finally, our study reveals differences in the performance of commercial and savings banks.     

Liquidity creation,regulatory capital,and bank profitability

We examine the interrelationships among liquidity creation, regulatory capital, and bank profitability of US banks. We find that regulatory capital and liquidity creation affect each other positively after controlling for bank profitability. However, this relationship is largely driven by small banks and primarily during non-crisis periods. It is also sensitive to the level of banks' regulatory capital and how it is measured. Furthermore, we find that banks which create more liquidity and exhibit higher illiquidity risk have lower profitability. Finally, the relationship between regulatory capital and bank performance is not linear and depends on the level of capitalization. Regulatory capital is negatively related to bank profitability for higher capitalized banks but positively related to profitability for lower capitalized banks. Therefore, a change in regulatory capital has differential impacts on bank performance. Our findings have various implications for policymakers and bank regulators.     

Board gender diversity,power, and bank risk taking

Having female board members brings ethical/societal perspectives and new resources to decision making. However, there is lack of evidence on whether it mitigates bank excessive risk-taking; hence, this paper addresses this question. It complements the normative corporate governance literature by combining agency theory and approach/inhibition theory of power from social psychology. For a sample of 195 U.S. commercial banks during 2002–2018, banks invest in more risky assets when female directors perceive the positive rewards of risky investments (in banks that have larger regulatory capital ratios and/or are well-capitalized) and when power shifts away due to CEO equity ownership. On the other hand, banks invest in less risky positions when female directors perceive the penalties inherent in a risky investment during the financial crisis. This paper provides novel evidence on the effect of gender diversity, as a governance mechanism, on risk taking in a social-psychology context. It offers insights on the effect of gender diversity on bank riskiness.     

Bank Risk, Capitalization, and Operating Efficiency

A simultaneous equation framework is used to test hypotheses about the interrelationships among bank interest rate and credit risk-taking, capitalization, and operating efficiency. A positive effect of inefficiency on risk-taking was found and supports the moral hazard hypothesis that poor performers are more vulnerable to risk-taking than high performance banking organizations. A positive effect of inefficiency on the level of capital is attributable to regulatory pressure on underperforming institutions. At the same time, firms with more capital are found to operate more efficiently than less well-capitalized banking organizations. A U-shaped relationship is detected between inefficiency and loan growth, indicating that operating efficiency improves at a decreasing rate as loan growth rate increases. This supports the hypothesis that entrenched managers who pursue a growth objective to enhance their own wealth tend to operate inefficiently.     

创新影响了银行风险承担吗?——基于中国上市银行的实证检验

本文将银行内部创新因素和外部创新环境引入银行风险承担研究框架,从理论和实证两个方面分析创新对银行风险承担的影响。研究结果发现,创新与银行风险承担之间呈现"U型"的关系,适度创新能够弱化银行风险承担,过度创新会加剧银行风险承担。进一步研究发现,内部创新对非五大行具有当期和滞后的双重影响,而对五大行仅具有当期效应。外部创新对五大行具有当期和滞后的双重影响,而对非五大行的当期影响不显著。企业还款能力、银行贷款质量和创新资产规模是创新影响银行风险承担的重要中介机制。此外,五大行对创新的敏感性小于非五大行,五大行可接受的创新区间大于非五大行。     

Bank risk-taking and corporate investment: Evidence from the Global Financial Crisis of 2007–2009

In this paper, we explore the relation between the banking sector's risk-taking and a firm's investment (“corporate investment”). Specifically, we ask whether firms' cash holdings moderate the effect of the banking sector's risk-taking on corporate investment. Based on a panel sample of publicly listed non-financial firms in 15 EU countries during the period 1990–2015, we document several key findings. First, both cash holdings and the banking sector's risk-taking are positively associated with corporate investment. Second, bank loan growth, which roughly captures the supply of bank credit, is not related to corporate investment. Third, firms with smaller cash holdings disproportionately invest more than do firms with larger cash holdings during periods of higher risk-taking by the banking sector.     

货币政策和银行风险承担：一种非线性关系

宽松的货币政策会通过估值、收入和现金流机制,追逐收益机制以及中央银行沟通和反应机制等渠道增加银行风险承担,通过风险转移机制降低银行风险承担,从而导致货币政策与银行风险承担之间可能存在复杂的非线性关系。本文使用面板阈值模型,基于我国银行业数据研究了货币政策对银行风险承担的影响,发现我国货币政策对银行风险承担的影响存在门限效应,即货币政策对银行风险承担的影响取决于货币政策基准利率偏离泰勒规则利率的程度。当这种偏离小于门限值时,宽松货币政策会增加银行风险承担;当这种偏离大于门限值时,宽松货币政策会降低银行风险承担。本文研究对更好地理解我国货币政策对银行风险承担及金融稳定的影响有一定参考意义。     

Political institutions and bank risk-taking behavior

This paper examines the impact of political institutions on bank risk-taking behavior. Using an international sample of banks from 98 countries over the period 1998–2007, I document that sound political institutions stimulate higher bank risk-taking. This is consistent with the hypotheses that better political institutions increase banks’ risk by boosting the credit market competition from alternative sources of finance and generating the moral hazard problems due to the expectation of government bailouts in worst economic conditions. While it is contrary to the hypotheses that better political institutions decrease banks’ risk by lowering the government expropriation risk and the information asymmetries between banks and borrowers. The results are robust to a number of sensitivity tests, including alternative proxies of bank risk-taking and political institutions, cross-sectional bank- and country-level regressions, endogeneity concerns of political institutions, country income levels, explicit deposit insurance schemes and sample extension from 1998 to 2014. I also examine the interdependence between political and legal institutions and find that political and legal institutions complement each other to influence bank risk-taking behavior.
