Measuring systemic risk with regime switching in tails

This paper motivates the importance of modeling nonlinearities in measuring systemic risk. I capitalize this motivation by generalizing the CoVaR approach proposed by Adrian and Brunnermeier (2016) to allow it switching between a high and a normal risk regime filtered from data.. Considering the U.S. large bank holding companies (BHCs), this paper shows that modeling regime changes in tails is capable of capturing both amplification and mean-reversion effects of an adverse shock to a bank's balance sheet on the banking system. Using the Kolmogorov–Smirnov test statistics with and without bootstrapping, I perform the significance test to identify systemically important financial institutions (SIFIs), and the stochastic dominance test to rank the identified SIFIs. The stochastic dominance test raises the concern that the CoVaR measure underestimates systemic risk contributions for SIFIs but overestimates for non-SIFIs. Finally, applying the BHCs' characteristics and housing market price to forecast the regime-switching systemic risk out-of-sample, I obtain from 4- and 8-quarter-ahead horizons a desirable countercyclical, forward-looking measure of systemic risk.     

基于SWOT分析的商业银行金融科技发展战略研究

金融科技（Fintech）以新兴技术为核心,对金融产品进行改造及创新,拓宽金融可 获得性,提高金融效率,有力地促进传统金融业的转型升级,已成为商业银行的战略重点和发 展方向。同时,商业银行发展金融科技也面临一系列劣势和困境,如缺乏高效组织架构、信息 科技系统难兼容等。本文在对相关文献回顾和评述的基础上,首先分析了商业银行发展金融科 技的背景;其次,重点运用SWOT分析法剖析商业银行发展金融科技的优势、劣势、机会和威 胁;最后,提出商业银行发展金融科技的对策建议：由内部研发、成立子公司,逐步过渡到外 部战略合作。     

Regulatory Capital Arbitrage and the Potential Competitive Impact of Basel II in the Market for Residential Mortgages

U.S. banking regulators have proposed a bifurcated system of capital regulation where the largest, internationally active banking organizations would be subject to significantly more risk sensitive regulatory capital requirements than are currently in place, while most others would remain subject to the current rules. The proposed new capital regime has the potential to affect the competitive landscape among banking institutions, particularly in the area of residential mortgage lending. We analyze the potential competitive effects of the proposed, bifurcated regulatory capital system on competition in the residential mortgage market from the perspective of the theory of regulatory capital arbitrage. We then apply the theory and available evidence to perform some benchmark calculations that suggest a significant, potential shift of market share and income to the largest banking institutions in the mortgage market.

The effect of capital requirement regulation on the transmission of monetary policy: evidence from Austria

This paper analyzes the role of banks’ regulatory capitalization in the transmission of monetary policy. We use a confidential dataset for Austrian banks spanning from the first quarter of 1997 to the fourth quarter of 2003. We find evidence that Austrian banks react in an asymmetric way to monetary policy depending on their regulatory excess capitalization, i.e. low capitalized banks react more restrictively to a monetary tightening than their highly capitalized peers.

Connecting National Safety Nets: The Dialectics of the Basel II Contracting Process

Basel II consists of supervisory guidelines negotiated by representatives of central banks and national regulatory commissions that were members of the Basel committee on Banking Supervision (BCBS). The BCBS is itself a regulatory response to globalization, which is connecting national safety nets in market-driven ways. A country’s financial safety net is a social contract established by short-lived agents for principals in long-lived economic sectors. Restraints placed on the authority of the BCBS members to contract for their principals by domestic politics explains: why Basel II authorizes individual countries to implement the agreement in markedly different ways; why US implementation of Basel II ran into so much doubt, controversy, and delay; and how the implementation debate set small and large banks and the Federal Reserve and other federal regulators against one another.

我国房地产泡沫与银行信贷规模的相关性研究

本文首先从理论上深刻剖析了房地产泡沫与银行信贷规模相互之间的作用与传导机制,在此基础上选取2006年-2018年相关指标的年度数据,对房地产泡沫与银行信贷规模进行了图形拟合与周期性波动规律分析,分析发现二者存在极高的契合度。建立房地产泡沫的函数,构建协整方程实证发现银行信贷规模对房地产泡沫的长期弹性系数为0.51,从长期来看银行信贷规模每增加1%,房地产泡沫也相应增加0.51%,进一步建立VAR模型实证发现房地产泡沫与银行信贷规模互为格兰杰因果关系,二者相互影响、相互促进。通过方差分解实证发现银行信贷规模对房地产泡沫的变动具有重要的影响,另一方面,房地产泡沫是影响银行信贷规模变动最主要的因素。     

金融科技与上市商业银行全要素生产率的研究——基于三阶段SBM-DEA模型

本文运用基于非径向和非角度以及包含非期望产出的三阶段SBM-DEA模型三阶段对我国28家上市商业银行2009-2018年的全要素生产率进行了测算和分析,并依据国有商业银行、股份制银行和城市商业银行属性进行异质性分析。同时使用固定效应模型对金融科技对银行全要素生产率的影响进行实证分析。研究结果表明：（1）商业银行金融科技的发展对上市银行全要素生产率有明显正向促进作用,主要的作用路径是通过促进商业银行产品与服务上的创新。（2）相较于城市商业银行,这种促进作用对国有银行和大型商业银行表现更大,尤其是大型商业银行。（3）效率分解为纯技术效率和规模效率后,商业银行金融科技的发展对银行纯技术效率的提升有正向促进作用,说明金融科技的发展对银行全要素生产率的作用更多表现在技术进步方面。     

商业银行市场营销体制依赖及理论模型——基于不同体制条件下的我国商业银行市场营销研究

银行市场营销活动总是在一定的体制背景下并依赖于一定的体制运行的,体制（或制度）是解释商业银行市场营销行为的重要变量。本文首先阐述了体制与制度的内涵及二者间的逻辑联系,阐明体制是制度的一部分;论证了市场营销对体制的依赖,体制要素结构为市场营销提供了资源配置的机制或方式;分析了体制或制度对银行市场营销的重要作用,指出体制是确保银行市场营销活动规范有序并持续获得高效益的根本保障;其后建立了商业银行市场营销的一般理论模型;最后分别以不同体制条件下商业银行市场营销的市场营销目标、营销变量特征、营销体制约束与激励条件的分析为依托,构建并比对了相应的经济转轨时期、市场体制下以及开放经济下商业银行市场营销的理论模型。     

金融生态环境、银行结构与银企关系的贷款效应——基于中小企业的实证研究

以深交所中小企业板上市公司在上市前的数据作为研究样本,本文实证考察了中小企业与银行之间的银企关系对其信贷融资可获性的影响,并在此基础上分析了银行规模与金融生态环境对中小企业的银企关系贷款效应的影响。实证结果显示,银企关系的密切程度对中小企业的信贷融资具有＂正＂向效应;金融生态环境的改善对银企关系的正向贷款效应具有促进作用;但不同规模的银行对银企关系的贷款效应无显著影响。本文的研究结果表明,在我国转轨经济条件下,广泛开展建立在银企关系基础上的关系融资技术有助于缓解中小企业融资难的问题,而金融生态环境的改善有助于此技术的开展,但银行业的市场结构对中小企业信贷融资无显著的影响。本文的研究结论为缓解中小企业融资难的问题提供了经验证据的支持。
