试论房价波动对商业银行资产的影响

基于次贷危机的启示,本文构建了在不同的金融发展程度下房地产价格波动对商业银行资产影响的理论模型,并在此基础上对中国的现状进行分析,指出当前对中国的影响主要集中于商业银行基于负债业务发放的贷款领域。进一步地,利用向量自回归模型(VAR)及冲击响应函数对中国房地产价格波动对商业银行贷款的影响进行了实证检验。研究表明:金融创新改变了房地产价格波动对商业银行资产的影响模式;中国房价波动对商业银行资产的影响主要集中在源于银行负债发放的贷款领域,但总体影响有限;中国应加快发展银行资产证券化业务,谨慎发展信用衍生产品。     

The relative and incremental explanatory powers of dirty surplus items for debt interest rate

This study investigates the relationship between dirty surplus items on the balance sheet and the cost of debt for Japanese firms. We focus on three dirty surplus items—unrealized gains and losses on available-for-sale securities (SEC), foreign currency translation adjustment (FOC), and land revaluation surplus (LAND). While many previous studies on dirty surplus adopted the value-relevance perspective, we examine the effect of dirty surplus items on the interest rate spread of bonds from the bond market perspective. We use the [Vuong, Q. H. (1989). Likelihood ratio tests for model selection and non-nested hypotheses. Econometrica, 57, 307–333] test to evaluate the relative explanatory power of the equity ratio with and without dirty surplus items for the interest rate spread on bonds issued. We find evidence that the equity ratio with dirty surplus items is more strongly associated with the debt interest rate than that without dirty surplus items. The results suggest that the total amount of dirty surplus items have statistically significant explanatory power for the interest rate spread. However, some dirty surplus items do not have explanatory powers for the bond interest rate spread. While FOC has relative and incremental explanatory powers and SEC has only incremental explanatory power, LAND has neither relative nor incremental explanatory power for the bond interest rate spread. The results mean that FOC and SEC are useful to Japanese bond investors.     

Tranching and Rating

In this paper we analyse the source and magnitude of marketing gains from selling structured debt securities at yields that reflect only their credit ratings, or specifically at yields on equivalently rated corporate bonds. We distinguish between credit ratings that are based on probabilities of default and ratings that are based on expected default losses. We show that subdividing a bond issued against given collateral into subordinated tranches can yield significant profits under the hypothesised pricing system. Increasing the systematic risk or reducing the total risk of the bond collateral increases the profits further. The marketing gain is generally increasing in the number of tranches and decreasing in the rating of the lowest rated tranche.     

Systemic and Idiosyncratic Risk in EU-15 Sovereign Yield Spreads after Seven Years of Monetary Union

The market capitalisation of international bond markets is much larger than that of international equity markets. However, compared to the large body of literature on international equity market linkages, there are far fewer empirical studies of bond systemic risk or international bond market co-movements. The extent of international bond market linkages merits investigation, as it may have important implications for the cost of financing fiscal deficit, monetary policymaking independence, modelling and forecasting long-term interest rates, and bond portfolio diversification. In this paper, we investigate the relative influence of systemic and idiosyncratic risk factors on yield spreads over 10-year German government securities during the seven years after the beginning of Monetary Integration. We estimate both panel regressions for the two groups of EU-15 countries (EMU and non-EMU) and specific-country regressions for the nine countries in the EMU group and the three countries in the non-EMU group. All estimations include both domestic (differences in market liquidity and credit risk) and international risk factors. The results present clear evidence that it was mostly idiosyncratic rather than systemic risk factors that drove the evolution of 10-year yield spread differentials over Germany in all EMU countries during the seven years after the beginning of Monetary Integration. Conversely, in the case of non-EMU countries, adjusted yield spreads (corrected from the foreign exchange factor) are influenced more by systemic risk factors. The fact that these countries do not share a common Monetary Policy might explain these results, which may show that government bonds from EMU countries have a better safe-haven status that those of non-EMU countries.     

我国地方政府债券发行长效机制的构建研究

在经历了长期的沉寂之后,我国的地方政府债券在2009年正式启动。虽然近期在二级市场上,地方政府债券遭到投资者的冷遇,但地方政府债券的持续发行有其理论与现实基础,从中国经济长远发展的角度考虑,应当构建地方政府债券发行的长效运行机制。在短期内应尽快建立地方政府债券发行的激励与约束机制以防范地方债务风险,在中长期应不断深化财政体制改革,逐步实现真正的地方政府债券制度安排。     

中国民营上市公司债务融资破产威胁功效的实证研究

以2002～2007年陷入财务危机的民营上市公司（ST公司）为研究样本．通过相关分析实证检验了中国债务融资的破产威胁功效.研究发现,中国民营上市公司债务融资总体上对财务状况恶劣的公司起到了债务治理作用,发挥了破产威胁功效。短期债务能够对陷入财务危机的民营上市公司起到改善业绩的作用,较好地发挥破产威胁功效,而长期债务未能发挥破产威胁作用。银行贷款能够促进陷入财务困境的民营上市公司改善业绩,发挥破产威胁功效,而商业信用却没能发挥破产威胁功效。     

Debt Maturity,Credit Risk,and Information Asymmetry: The Case of Municipal Bonds

Using a system of equations approach, this paper empirically tests the impact of credit quality, asset maturity, and other issuer and issue characteristics on the maturity of municipal bonds. We find that under conditions of lower information asymmetry that prevails in the municipal sector, higher‐rated bonds have longer maturities than low‐rated bonds. This result differs from that observed in the corporate sector. Overall, our results support the asset maturity hypothesis. In addition, our analysis finds that fundamentals matter. Issue features that provide additional protection or convenience to the investor tend to increase debt maturity.     

Earnings Management Surrounding New Debt Issues

We examine whether firms manage earnings before issuing bonds to achieve a lower cost of borrowing. We find significant income‐increasing earnings management prior to bond offerings. We also find that firms that manage earnings upward issue debt at a lower cost, after controlling for various bond issuer and issue characteristics. Our results are consistent with studies that report earnings management around equity issuance. The results indicate that, like equity holders, bondholders fail to see through the inflated earnings numbers in pricing new debt.     

基于共生网络的商业银行碳金融业务研究

碳金融共生网络是参与碳交易活动的银行、企业及各中介服务机构,以提升经济效益和自身发展为目的,通过多种合作方式实现整体综合效益最大化而形成的关系合集。在共生网络中,企业与关键种银行的联系最为紧密,银行信贷业务的调整直接关系着企业的融资活动。因此,银行针对企业制定一套标准化的、服务于碳金融的低碳信贷体系可以有效地促使企业融入碳金融的过程。本文分析了我国商业银行拓展碳金融市场存在的问题,提出应构建以银行为关键种的碳金融共生网络,以有效促使企业融入碳金融的参与过程。
