对中国信用卡消费群体特征的多元统计分析

本文在北京地区调查问卷的基础上设计了一套信用卡评价量表,通过多元统计中的因子分析、方差分析、卡方检验等手段分析信用卡评价变量与人口统计变量的相互关系,从量化的角度得出中国信用卡市场的基本现状和特点:信用卡各项服务的水平有很大的提升空间,开发潜力很大;信用卡的年费普遍过高;年轻群体相比于其他年龄群体对于信用卡的接受度、认同度、透支程度、及时还款程度都是最高的;信用卡的功能有待进一步开发;新功能的宣传所达到的效果较小;营销的细分市场应该主要通过透支额度和服务程度等来划分.最后文章还提出了相应的政策建议.     

Estimating the term structures of corporate debt

This paper investigates the corporate bond market by estimating monthly interest rate term structures for investment grade credit classes using both S&P's and Moody's ratings. Term structures are modeled by a piecewise constant forward rate curve and estimated on noncallable coupon paying bonds issued by industrial firms. The iterative estimation algorithm minimizes the sum of squared errors between market prices and model prices while identifying and removing outliers from the sample. Although the forward rate model is successful at pricing corporate debt, additional factors are found to be significant at explaining the residual price error that remains after the forward rate model is fit to market prices. Six necessary no-arbitrage conditions are derived for the term structures of risky and risk-free debt. Occasionally, some of these no-arbitrage conditions are violated and a few violations are asymptotically statistically significant. Finally, trading strategies that capture mispricing in the corporate debt market and violations of no-arbitrage bounds are discussed.This paper was adapted from my dissertation, completed at Cornell University. An earlier version of this paper was titled The Term Structures of Corporate Debt. Thanks to participants at the Cornell University finance workshop, Warren Bailey, Peter Carr, Antoine Giannetti, and especially Robert Jarrow for their helpful comments.     

Incorporating sustainability criteria into credit risk management

Does a commercial debtor's economic, environmental and social performance in terms of sustainability affect its credit risk rating? Does adding criteria aimed at assessing a lender's environmental, social or sustainability practices provide added value to traditional financial rating criteria? Many analyses have reported that a correlation exists between companies' environmental and their financial performance. We checked out the assertion that it ‘pays to be sustainable’ by analyzing the role that criteria pertaining to sustainability and environmental orientation play in the commercial credit risk management process. Our results show that sustainability criteria can be used to predict the financial performance of a debtor and improve the predictive validity of the credit rating process. We conclude that the sustainability a firm demonstrates influences its creditworthiness as part of its financial performance. Copyright © 2008 John Wiley & Sons, Ltd and ERP Environment.

Austrian Business Cycle Theory, Keynes’s General Theory, Soaring Wheat Prices, and Subprime Mortgage Write-Downs

Keynes’s presentation of own rates of interest on wheat and housing is set within Austrian business cycle theory, to show that soaring wheat prices and subprime mortgage writedowns are expected, when a monetary authority holds interest rates too low for too long. From that basis, further interest rate cuts are an unlikely remedy for a recession whose roots lie in a proliferation of credit.     

我国产学研合作应加强政府信用监管

产学研合作，是促进科技与经济结合，提高企业的科技创新能力，加快科技成果转化的重要方式，也是建设创新型国家和创新型城市的重要内容。产学研合作离不开信用制度的支撑。信用不仅是现代市场经济发展的基础，也是产学研合作有序发展的不可或缺的基本要素。如何加强政府对产学研合作信用的有效监管，并通过有效的制度安排，形成产学研合作的信用制度规范，就成为当前亟待解决的一个重要问题。

Correlation smile matching for collateralized debt obligation tranches with α-stable distributions and fitted Archimedean copula models

As an extension of the standard Gaussian copula model to price collateralized debt obligation (CDO) tranche swaps we present a generalization of a one-factor copula model based on stable distributions. For special parameter values these distributions coincide with Gaussian or Cauchy distributions, but changing the parameters allows a continuous deformation away from the Gaussian copula. All these factor copulas are embedded in a framework of stochastic correlations. We furthermore generalize the linear dependence in the usual factor approach to a more general Archimedean copula dependence between the individual trigger variable and the common latent factor. Our analysis is carried out on a non-homogeneous correlation structure of the underlying portfolio. CDO tranche market premia, even throughout the correlation crisis in May 2005, can be reproduced by certain models. From a numerical perspective, all these models are simple, since calculations can be reduced to one-dimensional numerical integrals.     

中国开行地方政府债券的先决条件研究

是否允许地方政府发行债券是一个颇具争议的话题。本文通过运用宪政经济学和新公共管理理论的分析方法,对开行地方政府债券发行权利的先决条件进行了论述。结合目前中国实际,文章认为目前开行地方政府债券的条件尚不完全具备,并建议下一步推进政府债券的关键在于可行性建设。     

The valuation of a firm’s investment opportunities: a reduced form credit risk perspective

This paper develops a valuation model for a firm’s investment opportunities. Given standard market imperfections, we show that maximizing the firm’s equity value is consistent with the need to include a capital charge for an investment specific to a firm’s capital structure and in excess of the investment’s market determined risk. A reduced form credit risk perspective is taken to enable a continuous time implementation. This continuous time implementation is illustrated within the paper.
