资产不透明的金融机构过度依赖批发性融资进行监管套利不利于系统性风险的防控。在此背景下,本文首先在经典银行道德风险模型的基础上引入关联性,从资产透明度和监管套利的视角分析银行系统性风险累积的内在机理。而后利用2007-2018年中国上市银行微观数据,构建资产透明度指标和系统性风险指标(SRISK、MES),对理论推论进行实证检验。主要结论有:(1)资产不透明、监管套利会提高银行的系统性风险。(2)监管套利弱化了资产透明度和资本监管机制对银行系统性风险承担的约束作用,资产透明度与资本监管机制在约束系统性风险承担中的协调作用不明显。(3)以大银行为主的债权银行受监管套利的影响相较于受资产透明度的影响更明显。在此基础上,我们对完善金融风险防范体系以及监管机制提出了若干建议。 相似文献

It is frequent to hear in economic seminars or read in academic papers that an effect is economically significant or economically important. Yet, the economic literature is vague on what economic importance means and how it should be measured. In this paper, I show that existing measures of economic importance are flawed and misused. I derive a new metric that measures, in percentage terms, the contribution of each explanatory variable to deviations in the dependent variable, ceteris paribus. As an illustration, the method is applied to study the determinants of migration and the determinants of fertility. 相似文献

For the purposes of financial stability, identifying financial institutions that, when in distress, could have a significant adverse impact on financial markets is important. A TrAffic LIght System for Systemic Stress (TALIS-cube) is proposed that provides a comprehensive color-based classification for grouping companies according to both the stress reaction level of the system when the company is in distress and the company’s stress level. TALIS3 can integrate multiple signals from the interaction between different risk metrics. Starting from specific risk indicators, companies are classified by combining two loss functions—one for the system and one for each company—evaluated over time and as a cross section. An aggregated index is also obtained from the color-based classification of companies. TALIS3 can be used to enhance the performance and robustness of existing systemic risk measures. An empirical analysis of the U.S. market is also provided. 相似文献

The post-crisis regulatory architecture targets greater banking stability by imposing additional capital and liquidity requirements. Profit persistence, however, remains an important factor for attaining this goal. Using annual data for 2008–2017, this study analyzes the relationship between funding stability, systemic importance, and the profitability of banks in the three founding states of the Eurasian Economic Union (EAEU): Russia, Kazakhstan, and Belarus. The results show a strong degree of stability in net interest margin (NIM) and a lack of persistence in return on assets (ROA). Compliance with the minimum level of the Net Stable Funding Ratio (NSFR) reduces both the funding liquidity risk and the NIM of EAEU banks. Moreover, systemically important banks in the region historically operate at a lower interest spread and less prudent NSFR, which implies a potentially greater adverse effect on their NIM. Bank-specific variables have various impacts depending on the measure of profitability. The results also highlight that greater market concentration protects the NIM and negatively impacts the ROA of EAEU banks. Finally, Western sanctions have a destabilizing effect on the NIM of EAEU banks, but not on systemically important banks. 相似文献

We analyze the institutional determinants of U.S. financial market regulation with a general model of the policy-making process in which legislators delegate authority to regulate financial risk at both the firm and systemic levels. The model explains changes in U.S. financial regulation leading up to the financial crisis. We test the predictions of the general model with a novel, comprehensive data set of financial regulatory laws enacted specifically between 1950 and 2009. The theoretical and empirical analysis finds that economic and political factors impact Congress’ decision to delegate regulatory authority to executive agencies, which in turn impacts the stringency of financial market regulation, and our estimation results indicate that political factors may have been stronger and resulted in inefficiencies. 相似文献

Determining price per room to be charged to customers is an important decision to be taken by hotel management. Hotels frequently change their room rates based on the demand of room, occupancy rate, seasonal pattern, and strategies undertaken by other hotels on pricing. We formulated four models to analyse how various influencing variables, such as hotel price, demand, yearly trend and monthly seasonality influence hotel revenue per available room (RevPar). To analyse a case, we used monthly accommodation statistics for Sweden taken for Swedish Agency for Economic and Regional Growth and Statistics from January 2008 to July 2017. We carried out data analysis using both multiple regression and Multivariate Adaptive Regression Splines (MARS) model and found that application of MARS can help establishing a nonlinear relationship of RevPar with other determining variables in a superior way. We also proposed the possibility of developing a better forecasting model using MARS. 相似文献

文章基于溢出指数和波动溢出网络方法,从静态和动态分别度量我国金融系统不同子市场间的风险联动水平及变动趋势。研究结果表明,我国金融系统风险溢出效应整体水平较高,各市场间联动性较强;市场内部滞后效应大于市场之间溢出效应,两两有向溢出效应具有强不对称性;作为我国金融系统的风险中心,货币市场始终处于风险溢出方,但在金融危机时期,其对外风险溢出效应相对减弱,而大宗商品市场、资本市场、房地产市场等其余市场的风险溢出效应相对增强。值得注意的是,当前我国金融系统整体风险溢出水平较高,市场间风险相关性较强,需要进一步加强系统性风险的监测与防范。 相似文献

本文基于2007年至2019年我国14家上市银行的股票收益率,构建偏态t-分布动态因子Copula模型,利用时变荷载因子刻画单家银行与整个系统的相关性,计算联合风险概率作为系统性风险整体水平的度量,基于关联性视角提出了新的单家机构系统脆弱性和系统重要性度量指标——系统脆弱性程度和系统重要性程度。该方法充分考虑了银行个体差异性和系统的内在关联性以及收益率的厚尾性和非对称性,从而能够捕捉到更多的信息且兼具时效性。研究表明:银行机构在风险聚集时期相关程度更大,联合风险概率能够准确识别出系统性风险事件且在我国推行宏观审慎评估体系以后有明显降低;整体而言,大型商业银行系统重要性水平最高,同时风险抗压能力也最强;本文使用的度量方法降低了数据获取成本且更具时效性,有助于为宏观审慎差异化监管工作提供借鉴和参考。 相似文献
