银行业市场竞争对企业技术创新的影响研究

银行贷款是企业创新的重要融资来源,银行业市场的变化影响着企业技术创新的融资环境.基于2008-2014年沪深A股上市公司的实证检验发现:银行市场竞争性的提高有利于缓解企业的融资约束,促进企业技术创新.企业规模对中小企业的技术创新有正向的影响,对大型企业存在负的效应.银行业市场竞争对企业技术创新的影响也因企业规模不同而不同,中小企业受到的融资约束明显,银行业竞争度的提高更有利于促进中小企业的技术创新.     

融资约束对企业出口影响的Heckman验证-基于银行信用风险的视角

基于中国工业企业数据库1998-2014年7032家企业的平衡面板数据,从银行信用风险内部评级的视角,研究融资约束对企业出口的影响.结果表明:银行信贷融资约束与企业的出口决策及出口强度间有显著负相关关系.同时,使用Heckman二阶段模型研究发现:不同形式的商业信用对企业出口决策及出口强度的影响和作用机制会因企业所处供求端位置的不同而存在差异.其中,需求端的商业信用仅与企业出口决策显著正相关,而与出口强度的相关性并不显著;供给端的商业信用则与企业出口强度显著负相关.     

Too big to fail: Measures,remedies, and consequences for efficiency and stability*

This paper evaluates whether reform efforts addressing “too big to fail” actually enhance the stability of the financial system, and whether trade‐offs exist between stability and efficiency. We also present and discuss various measures of bank size and complexity since such measures are essential for implementing appropriate corrective remedies. As we will show, there are no unambiguous measures of size or complexity that can fully capture a bank's contribution to systemic risk. Their effects on efficiency are also impossible to capture with certainty. While we recognize the need for additional research and empirical evidence, we do identify weaknesses and strengths of proposed and implemented reforms that could have consequences for bank stability and efficiency.     

Bank Capital Regulation of Trading Portfolios: An Assessment of the Basel Framework

In setting minimum capital requirements for trading portfolios, the Basel Committee on Banking Supervision (1996, 2011a, 2013) initially used Value‐at‐Risk (VaR), then both VaR and stressed VaR (SVaR), and most recently, stressed Conditional VaR (SCVaR). Accordingly, we examine the use of SCVaR to measure risk and set these requirements. Assuming elliptically distributed asset returns, we show that portfolios on the mean‐SCVaR frontier generally lie away from the mean‐variance (M‐V) frontier. In a plausible numerical example, we find that such portfolios tend to have considerably higher ratios of risk (measured by, e.g., standard deviation) to minimum capital requirement than those of portfolios on the M‐V frontier. Also, we find that requirements based on SCVaR are smaller than those based on both VaR and SVaR but exceed those based on just VaR. Finally, we find that requirements based on SCVaR are less procyclical than those based on either VaR or both VaR and SVaR. Overall, our paper suggests that the use of SCVaR to measure risk and set requirements is not a panacea.     

Central Bank Actions and Words: The Intraday Effects of FOMC Policy Communications on Individual Equity Volatility and Returns

We compare intraday impacts of the release of Federal Reserve decision announcements and of Federal Open Market Committee minutes between 2004 and 2015 on 1,997 equity return and volatility series. We find that returns are unresponsive to either news release, but conditional volatility increases for both, manifesting immediately after each information release, and persisting for 30 minutes post‐announcement. These effects are larger for decisions than for minutes. On stratifying firms by trading intensity, we find most “high trading intensity” firms respond to these announcements, while “low trading intensity” firms are less affected. Our results show that traders respond, albeit differently, to both sets of information releases.     

An Empirical Study of International Spillover of Sovereign Risk to Bank Credit Risk

The severity and complexity of the recent financial crisis has motivated the need for understanding the relationships between sovereign ratings and bank credit ratings. This is the first study to examine the impact of the “international” spillover of sovereign risk to bank credit risk through both a ratings channel and an asset holdings channel. In the first case, the downgrade of sovereign ratings in GIIPS (Greece, Italy, Ireland, Portugal, and Spain) countries leads to rating downgrades of banks in the peripheral countries. The second channel indicates that larger asset holdings of GIIPS debt increases the credit risk of cross‐border banks, and hence, the probabilities of downgrade.     

Efficiency in Turkish banking: post-restructuring evidence

Turkish banking sector went through a significant restructuring process in the aftermath of the country's financial crisis of 2000–2001. In this paper, we analyze the evolution of banking performance using a novel approach due to Ray [(2007). “Shadow Profit Maximization and a Measure of Overall Inefficiency.” Journal of Productivity Analysis 27, 231–236]. We derive ‘shadow unrealized profit scores’ as well as ‘shadow input–output prices’ for each year and bank in the sector from 2002 to 2011. We argue these scores operationalize the Hicksian concept of ‘monopolistic quiet life’. We provide some evidence the sector came closer to the ‘zero profit condition’ as well as displaying a closer approximation to the ‘law of one price’ over time. We show the variability of these ‘shadow prices’ essentially coincides with that of corresponding actual prices. We utilize shadow price information to show that business models and competitive choices of banks differ across ownership types with foreign banks competing on the broadest front compared to state-owned and privately owned Turkish banks.

代理行业务反洗钱管理研究

代理行业务作为商业银行国际业务的重要组成,对于促进跨境金融活动、支撑国际贸易、推动包容性增长等方面具有重要意义。但由于该业务的内生特点,往往隐藏着较大的洗钱风险。近年来代理行业务洗钱案件频现,凸显了代理行业务在风险治理、尽职调查、风险评估、交易监控等方面的问题。商业银行要稳健发展好代理行业务,需要从事前、事中、事后等环节加强反洗钱管理。
