金融创新产品风险的适应性监管机制探索——以MBS、CDO、CDS为例

金融创新产品风险的监管不到位是2007年美国次贷危机及2008年全球金融危机爆发的主要原因之一。在对MBS、CDO与CDS等创新产品风险及监管进行分析基础上创建的金融创新产品风险适应性监管机制框架包括风险的识别、风险的层级报告、风险的预警、风险的监管介入、风险的处理和金融危机与经济危机的预防六个部分。     

河北省贫困农村地区信贷担保体系的建立及模式选择

"三农"问题的解决离不开农村金融的支持。然而河北省贫困农村地区却是"农民贷款难、金融机构难贷款"并存。本文认为设立农村信用担保机构、选择适合贫困地区的担保模式将有助于这一矛盾的解决。     

日元升值预期下日本国际投资策略与特点

1971年至1995年期间,日元处于急剧升值阶段,在此之后的十多年里日元升跌互见,整体波动缓和,2008年初以来日元持续升值。在日元升值预期的作用下,自20世纪90年代以来,日本加大了海外直接投资的力度,近2/3的资金流向了经济比较发达的国家和地区。与海外直接投资相比,日本的证券投资规模较大,占海外资产总额的近五成,其投资组合策略注重汇率风险管理,始终保持了一贯的连续性,重视资产的安全性和回报率。日本也加快了以其他方式向海外输出资本的步伐,按照国际收支状况的统计口径,这些投资包括对外贷款、贸易信贷、货币及存款和其他资产,其规模仅次于海外证券投资。研究表明,日本的海外投资区域分布和币种选择体现了分散投资、降低风险的特点,也在较大程度上降低了汇率风险。     

信贷配给、流动性冲击和民营企业现金持有

融资约束的存在要求企业持有必要的现金以预防可能的流动性冲击。不同于以往研究,本文从融资数量的硬约束——信贷配给视角将企业现金持有水平及其经济后果的考察纳入到一个统一的理论框架,并运用实证的方法研究流动性冲击下我国民营上市公司的现金持有行为。研究表明：民营上市公司持有高额现金的原因出于在信贷配给约束下的预防性动机;在遭受流动性冲击时,增持现金对民营上市公司具有正向的价值效应,且信贷配给水平越高的企业这种正向效应越显著。     

我国消费信贷中个人信用制度建设的思考

消费信贷作为刺激消费、扩大内需、推动生产、拉动经济的重要举措,促进了我国消费市场的发展,也推动了个人信用制度建设的发展,但消费信贷中的违约风险也随之加大。本文根据我国消费信贷中个人信用制度的发展现状,围绕消费信贷来分析信用制度缺失对消费信贷带来的风险,从而提出了建立和完善行之有效的个人信用制度的政策建议。     

Does scoring a subpopulation make a difference

Scorecards used by consumer credit providers to assess the probability that an applicant will default are usually built for the population of potential applicants as a whole. This paper investigates whether it is permissible and worth-while to build a separate scorecard for each subpopulation of applicants. We review the legal requirements to find that it is permissible to use separate scorecards for many, but not all, personal characteristics. Second, using data supplied by a credit card organization separate scorecards were built for several subpopulations for each of twelve personal characteristics. The predicted performance of each was compared with that gained form estimating a scorecard for the full population using three methods for setting the cut-off scores in an `independent' way. These methods differ in the degree to which the cut-off scores are independent of information about other subpopulation, in the level of discrimination achieved between likely good payers and defaulters and in the degree to which each method is robust to new data. We conclude, first, that creating scorecards using subpopulations does not necessarily give better discrimination between likely good payers and defaulters. Second, none of the three methods examined to set the cut-off scores dominates the others using the three desirable properties described; trade-offs are required. Finally, subpopulation scorecards lead to the rejection of fewer applicants than scorecards built on full populations.     

Capital,credit constraints and the comovement between consumer durables and nondurables

Evidence indicates that consumer durables are more flexibly priced than nondurable goods and services. In otherwise standard two-sector neoclassical sticky-price models with flexible durable prices, following monetary tightening, nondurables decrease but consumer durables increase. Friction in lending between households can resolve the comovement problem if durable prices are sticky. However, if durable prices are flexible, friction in lending fails to generate joint decline. This paper resolves the co-movement problem by adding capital into a model with flexible durable prices and friction in lending. When capital is needed in production, monetary tightening reduces the relative price of durables which induces investment and decreases firms' real profits in the short run. Due to fewer profits remitted from firms, savers have a lower disposable income and cannot increase expenditures on consumer durables as much as otherwise. As a consequence, aggregate consumer durables decrease and there is a joint decline of nondurables and consumer durables.     

The cost of deviating from the optimal monetary policy: A panel VAR analysis

Exploiting the panel VAR GMM estimator's features, macroeconomic country factors are combined with micro-economic bank data to test for the risk taking channel in the Euro Area. According to prior expectations based on an extended DSGE model, the analysis demonstrates that the monetary policy incentives bank risk taking by increasing the bank leverage, but it is not able to influence the level of credit risk. However, deeper investigations indicates the Taylor gap adds to the bank risk appetite in all its forms, while regarding the reactions to target variables, movements in the interest rate smooth the bank risk.     

Credit lender–borrower relationship in the credit card market – Implications for credit risk management strategy and relationship marketing

Lehman Brothers filed for bankruptcy in 2008, precipitating the international financial crisis. Many questioned the banks’ risk-taking credit system. Understanding credit risk and how the credit system functions may provide knowledge on managing credit, to avoid another such international crisis. We study the credit card field and present a pricing decision model for managing credit risk. Recent credit lenders’ portfolio re-pricing practices call for immediate attention to the credit lender–borrower relationship and relationship marketing. A literature review and recent phenomena in the credit card industry reveal that the lenders’ re-pricing strategy negatively affects the credit lender–borrower relationship and relationship marketing. Thus, we introduce a pricing decision model incorporating the lenders’ re-pricing strategy and the credit lender–borrower relationship. Further, we discuss the implications of, and the role of marketing in, credit risk management and the implications of relationship marketing for credit lenders in foreign markets, including the US market.     

征信体系的作用与效率——基于信息不对称随机有限重复博弈的分析

征信体系的意义可以用重复博弈理论来加以解释.本文建立了一个信息不对称随机有限重复信用博弈模型,证明如果存在征信体系实现的信息共享机制,那么不论借款者的类型是什么,诚实守信是可以作为序列均衡的结果在有限重复博弈的绝大多数时期中出现的.如果不存在信息共享机制,信贷市场有可能消失,即便引入资产抵押,信贷市场仍是不完全的.基于上述序列均衡分析,本文进一步阐释了全面征信、法律保障、市场结构对征信体系效率运行的重要性.就发展中国家而言,成立中性、独立、信息全面的国家信用局和鼓励民营信用公司积极竞争,完善义务征信的法律体系是较为理想和可行的选择
