中国信用体系建设中的个人信用模糊评估

个人信用体系建设是中国信用制度建设的主要内容之一，个人信用评估是个人信用体系建设的主要应用领域。在信用评分模型和基于先验审批规则法基础上建立起来的模糊推理系统，充分利用了业内人员多年积累的从业经验，是适合我国实际情况的个人信用评估方式。在我国个人信用数据积累到一定程度和一定时期之后，这些数据既可以与专家经验互相补充用于生成模糊推理规则，也可以对模糊推理系统进行检验和修正。

The provision of long-term credit and firm growth in developing countries

Do small and young firms benefit from an increase in the provision of long-term loans? By combining firm-level data from 62 countries (over the period 2006–2016) with a new database on short-term and long-term credit provided to the private sector, this article shows a higher provision of long-term credit does not stimulate growth of small and young firms. On the contrary, an increase in the availability of short-term credit spurs firm growth. The main explanation of this (counter-intuitive) result is the differential impact of short-term and long-term credit provision on small and young firms’ access to credit. Young and small firms are able to take advantage of an increase of short-term loans, which allow them to switch from informal finance to bank loans. However, a higher level of long-term credit does not alleviate credit constraints faced by opaque firms because these funds are allocated towards transparent borrowers.

Modeling the dependence structure between default risk premium,equity return volatility and the jump risk: Evidence from a financial crisis

This paper investigates the dependence structure between default risk premium, equity return volatility and jump risk in the equity market before and during the subprime crisis. Using iTraxx CDS index spreads from Japanese and Australian markets, the paper models the different relationships that can exist in different ranges of behavior. We consider several Archimedean copula models with different tail dependence structures, namely, Gumbel, Clayton, Frank, AMH and Joe copulas. Although the dramatic change in the levels of the iTraxx CDS index, we find strong evidence that the dependence structure between CDS and stock market conditions is asymmetric and orienting toward the upper side. In addition, we find that the Japanese CDS market is more sensitive to the stock return volatility than the jump risk and the magnitude of this sensitivity is related to the market circumstances. However, Australian CDS market is more sensitive to the jump risk than stock return volatility before and during the financial crisis. This result has important implications for both global financial stability and default risk management. Specifically, the heterogeneity of markets, coupled with the diversity in the risk exposures cause the default risk premium and equity markets to exhibit different levels of sensitivity.     

商业银行信用风险与宏观经济——基于压力测试的研究

本文采用压力测试框架,研究了宏观经济波动对商业银行信用风险的影响。文章以不良贷款率度量信用风险,以名义GDP增长率、广义货币供应量（M2）增速、居民消费价格指数（CPI）以及房地产销售价格指数作为宏观经济变量,建立了合适的宏观压力测试模型。在GDP增速放缓、CPI上升、M2增速下降的压力情景下,预测了2011年第一季度到第四季度的不良贷款率的变化路径。实证结果表明在压力情景下商业银行的不良贷款率将会显著上升。     

The effects of the 2005 Bankruptcy Reform in Brazil

This paper studies the effect of the 2005 Bankruptcy Reform in Brazil. Using firm-level data we found that the increase in the level of creditors' protection reduced the cost of debt and increased the amount borrowed by the firms.     

债务融资结构与产品市场竞争决策研究

资本结构的产品市场竞争理论认为,在特定竞争模型下债务融资结构能够反映企业的产品市场竞争策略,并认为短期债务增加加剧了产品市场竞争,长期债务缓和产品市场竞争。进一步的实证分析得到短期债务融资与产品市场竞争程度是显著负相关的,长期债务融资与产品市场竞争程度是显著正相关的,能够支持产品市场竞争理论。同时,数据分析发现,企业规模小、资产利用效率高和收益好也是促使企业采取激进竞争手段的影响因素。     

上市公司债务融资短期化成因与治理方略

短期债务具有流动性好、财务灵活性强、名义利率低等一系列优势,但过量短期债务的使用会给企业带来较大的财务风险。鉴于我国上市公司债务融资存在的严重短期化现象,应针对这种短期化债务融资的弊端与成因,提出改变不良状况的学术见解和解决问题的方略。     

Discount rates and credit markets: Theory and evidence from rural india

Three models of credit markets - (1) the permanent income model, (2) upward sloping credit supply to individual borrowers, and (3) constrained credit due to imperfect enforcement - are tested using credit market data and an experimental study of individuals' discount rates in south India. The permanent income model is rejected by both the discount rate and the credit market data. The discount rate data are consistent with either of the other two models, while the credit market data are consistent with a combination of these two models. Other explanations are found to be insufficient to explain the results of this study.
