On International Consumption Risk Sharing,Financial Integration and Financial Development

This article investigates the empirical link between international consumption risk sharing, financial integration, and financial development for a group of twenty-nine developed and developing countries in the G7, the Euro area, and the OECD. Estimation results indicate that (1) risk sharing in the Euro area is higher than those in the G-7 and the OECD, and (2) a higher degree of risk sharing is associated with a greater degree of financial integration and a lower level of financial development. These results suggest that more financially integrated countries might be better able to insure themselves against idiosyncratic income shocks and countries with more developed financial markets might tend to engage in less consumption risk sharing with other countries thanks to their own sophisticated financial markets. Holding financial integration and financial development equal, countries in the Euro area engage in significantly more risk sharing than the ones in the G7 and the OECD.     

基于银行同业网络与资产重叠的金融风险传染研究

本文分析当银行遭受不同类型初始冲击时,传染概率、传染范围、损失程度随资产多样化程度、初始冲击程度变化的分布情况。研究表明,在两类传染途径共同作用下,资产多样化程度和初始冲击程度很低时风险传染概率与范围仍呈现较高水平,资产多样化程度较高时风险传染概率与范围呈现较低水平;不同网络结构中资产多样化对于初始冲击具有不同的吸收能力,且传染范围呈现出明显的由稳定转向非稳定的相变过程;在传染范围稳定的区域,损失程度仍随资产多样化程度的增加而增大。     

信息共享、风险分担与农村银保互动机制

通过保险分散农村信贷所蕴含的风险是农村信贷风险分担的重要途径,也是农村金融发展的主要趋势。农村银保间信息共享可以有效防止信息不对称造成的逆向选择;农村银保间风险分担可以通过利益捆绑和激励相容解决道德风险。通过研究张家界市的＂信贷＋保险＂缔约过程与履约条件发现,银保合约创新分担了信贷机构的信贷风险,改善了缔约中的信息结构,降低了保险机构的运行成本,提高了农村金融体系的效率。     

Liquidity, Transaction Costs, and Reintermediation in Electronic Markets

Relationships between trading cost, technology, and the nature of intermediation in the trading services industry are discussed. Electronic markets are linked to reductions in trading costs. Lower explicit costs are related to system development and operating costs. Electronic order book information is identified as a means of realizing implicit cost savings. The concept of liquidity management in electronic environments is introduced, and its potential is empirically illustrated. The empirical results suggest new roles for brokerage and exchange operations, and competition between the two. Competitive advantage with respect to the provision of liquidity management services is compared across types of intermediaries.     

Deposit Insurance, Capital Regulations, and Financial Contagion in Multinational Banks

Abstract:  Banking sector globalization has caused an expansion in foreign-owned bank assets. In this paper we analyse the effects of a MNB's liability structure upon its investment in a foreign country. We develop a model in which capital adequacy requirements introduce some deliberate underinvestment which counters deposit insurance-induced overinvestment. Diversification is unattractive with fixed bank capital requirements, because it reduces the expected value of the deposit insurance net. This effect applies in multinational banks (MNBs), where shocks to the home country economy alter the value of the deposit insurance net and hence affect overseas lending incentives. Thus, MNBs act as a channel for financial contagion. We discuss the policy implications of our results.     

信用违约风险传染模型的比较研究

Uncertainty in an Interconnected Financial System,Contagion, and Market Freezes

This paper studies contagion and market freezes caused by uncertainty in financial network structures. Our model demonstrates that in a financial system where financial institutions are interconnected, a negative shock to an individual financial institution could spread to other institutions, causing market freezes because of creditors' uncertainty about the financial network structure. Our model also reveals that when both a large creditor and a continuum of small creditors are present, the size of the large creditor will affect the severity of market freezes substantially. Moreover, our model is used to examine central bank policies to alleviate market freezes.     

金融创新、金融风险与中国金融监管模式

金融创新对宏观政策的制定、金融市场运行、商业银行透明度均有影响,它能够管理和控制金融风险,也能增大金融风险,还将对金融稳定性产生很大的负面影响。中国的金融监管应建立健全银行、证券、保险监管机构间以及与宏观调控部门的协调机制,通过中国金融监督管理委员会与国际性金融监管组织的合作,积极参与国际金融监管准则的制定,借鉴国外金融监管经验,不断提高金融监管的专业化水平。     

我国财政债务风险分析

近几年大力扩张国债使我国潜在的财政债务风险浮出水面。为保证我国经济持续发展，2001年积极财政政策仍需继续发放国债，我国财政债务风险主要体现为中央财政债务风险较大，适度调整国债政策是防范中央财政债务风险的要求。加强外债管理，调整内债期限结构、持有者结构、完善偿债基金制度，尝试增发地方国债等措施，是化解中央财政债务风险的现实选择。     

Liquidity Coinsurance, Moral Hazard, and Financial Contagion

We study the propagation of financial crises among regions in which banks are protected by limited liability and may take excessive risk. The regions are affected by negatively correlated liquidity shocks, so liquidity coinsurance is Pareto improving. The moral hazard problem can be solved if banks are sufficiently capitalized. Under autarky a limited amount of capital is sufficient to prevent risk‐taking, but when financial markets are open capital becomes insufficient. Thus, bankruptcy occurs with positive probability and the crisis spreads to other regions via financial linkages. Opening financial markets is nevertheless Pareto improving; consumers benefit from liquidity coinsurance, although they pay the cost of excessive risk‐taking.     

双传染渠道下银行系统性风险的测度研究

运用改进后的双传染渠道模型,依据2014—2022年42家银行的年报数据,从传染损失、倒闭机构数、银行系统损失和溢出至经济系统损失四个维度测度我国银行系统性风险。结果显示,从传染损失或倒闭机构数量单个维度测量系统性风险并分析其生成机制过于片面。综合银行系统损失和溢出至经济系统损失维度能更全面、准确地测度银行系统性风险。降价抛售、债务违约分别是权益损失、银行破产的主要渠道。杠杆高且银行间贷款占比高的银行更脆弱,溢出风险更大。     

Financial intermediation and the supply of liquidity

I study the role of financial intermediaries in supplying liquidity to the real economy. Firms hold liquid assets to meet unanticipated expenses. Financial intermediaries supply liquidity by pooling partially liquid assets, but their ability to commit future funds depends on their capital. When liquidity is scarce, there is a positive liquidity premium and investment is inefficiently low. Bank losses raise the liquidity premium and reduce investment. I analyze the optimal supply of public liquidity and find that when private liquidity is scarce the government should issue bonds for their liquidity properties, providing justification for countercyclical budget deficits.     

国内外黄金市场风险传染的实证研究

以国际黄金市场上具有代表性的伦敦黄金现货价格和我国上海黄金交易所的黄金现货价格作为研究对象,利用多元GARCH模型对国内外黄金市场的风险传染机制进行了实证研究。结果表明：伦敦黄金市场对我国黄金市场存在单方向的均值溢出效应;从波动溢出效应来看,伦敦黄金市场对我国黄金市场的风险传染强于我国黄金市场对伦敦黄金市场的风险传染,存在着风险传染的非对称性。     

Sovereign Risk Contagion in East Asia: A Mixture of Time-Varying Copulas Approach

This study analyzes sovereign risk contagion between four East Asian economies (China, Hong Kong, Japan, and Korea) and its structural changes through the Global Financial Crisis (GFC) and the European Debt Crisis (EDC) by applying the mixture of time-varying copulas to those economies’ credit default swap (CDS) spreads.

This article first finds a strong contagion from the US and PIIGS economies to the East Asian sovereign CDS markets and intraregional contagion within the East Asian markets. Second, the impact of contagion is different according to whether it is measured by the linear (Gaussian) or the upper tail dependence. Third, Japan plays an important role in increasing the linear dependence whereas China and Korea are crucial in terms of the upper tail dependence. Lastly, the GFC has structurally increased the linear dependence but not the upper tail dependence between the East Asian sovereign CDS markets.     

债券违约对流动性影响的传染效应研究

2014年以来我国信用债市场违约事件频发,信用风险的积聚可能引发债券市场流动性恶化。本文以2014―2019年交易所和银行间市场信用债为研究对象,实证考察违约事件对债券流动性影响的传染效应。研究发现:违约事件在同一发行主体的债券之间具有流动性传染效应,当公司的某期债券出现违约时,公司其他未到期债券的流动性水平显著下降;违约事件对同行业其他公司债券的流动性具有传染效应,当行业中出现债券违约事件时,行业内其他公司的债券流动性显著降低;违约事件爆发越密集或者违约事件越严重,对债券流动性的负面影响越大,而且民营企业债受到的影响要大于国有企业债,低信用等级债受到的影响要大于高信用等级债;在市场密集爆发违约事件或出现较为严重的违约事件时期,宏观流动性增加能够改善债券流动性。     

Interbank Credit Lines as a Channel of Contagion

This paper assesses the potential for contagion in the Swiss interbank market using new data on bilateral bank exposures as well as on credit lines. A simulation approach is applied to assess the banking system's inherent instability. Moreover, the spill-over effects of a simulated default situation in the interbank market on the liquidity and solvency of banks are measured. The main findings are, first, that there is a substantial potential for contagion. Second, the exposure as well as the credit line contagion channel are relevant for Switzerland. Third, a lender of last resort intervention could reduce spill-over effects remarkably. Finally, the structure of the interbank market has considerable impact on its resilience against spill-over effects: Centralized markets are more prone to contagion than homogenous ones. JEL classification: C81, G21. The opinions expressed herein are my own and not those of the Swiss National Bank.

Further Evidence on Equity Market Contagion: the FSLIC's Solvency and the Liquidity Crisis of Financial Corporation of America

Whether pure contagion is more likely to occur when a federal deposit insurer is severely undercapitalized is an unanswered question. This paper provides evidence on this issue by examining the stock market reaction of savings and loans (S&Ls) to the crisis of Financial Corporation of America (FCA) in 1984, when the Federal Savings and Loan Insurance Corporation was fiscally unsound. Consistent with a contingent insurance guarantee hypothesis, the results show large, significant negative abnormal returns (ARs) for a portfolio of high insured deposit S&Ls during FCA's crisis.
