我国涉外企业外汇交易风险研究

随着世界经济逐步向全球一体化的方向发展以及我国对WTO相关条款的逐步履行,我国与其他国家的经济往来也变得更加频繁。更为重要的是,我国外汇管理体制改革的进一步深化和外汇市场的发展和完善,使得人民币汇率开始走向市场,汇率变动的频率和范围将大大增强。因此,在这一背景下,本文以科学性和前瞻性为指导原则,通过阐述我国涉外企业面临的外汇交易风险现状和问题,揭示这类企业加强外汇交易风险管理的必要性,在此基础上,来探讨外汇交易风险对我国涉外企业净利润的影响,最终结合我国外汇管理体制改革的实践,提出有效防范和规避外汇交易风险的建议和对策。

Modelling return and conditional volatility exposures in global stock markets

This article empirically investigates the exposure of country-level conditional stock return volatilities to conditional global stock return volatility. It provides evidence that conditional stock market return volatilities have a contemporaneous association with global return volatilities. While all the countries included in the study exhibited a significant and positive relationship to global volatility, emerging market volatility exposures were considerably higher than developed market exposures.

An integrated multi-model credit rating system for private firms

This paper presents a integrated credit risk modelling approach for private firms which fulfil 2001 Basel Accord requirements in the case of the adoption of the foundation approach. Our model comprises: (a) a bottom-up technique to initially assess the through-the-cycle one-year Probability of Default (PD) and (b) a top-down approach to refine and calibrate this historical PD in a forward-looking credit risk assessment based on next year’s economic outlook. We present findings from applying this model to a large sample of client firms of the Bank of Rome.     

Valuation of vulnerable American options with correlated credit risk

This article evaluates vulnerable American options based on the two-point Geske and Johnson method. In accordance with the Martingale approach, we provide analytical pricing formulas for European and multi-exercisable options under risk-neutral measures. Employing Richardson’s extrapolation gets the values of vulnerable American options. To demonstrate the accuracy of our proposed method, we use numerical examples to compare the values of vulnerable American options from our proposed method with the benchmark values from the least-square Monte Carlo simulation method. We also perform sensitivity analyses for vulnerable American options and show how the prices of vulnerable American options vary with the correlation between the underlying assets and the option writer’s assets.      

我国商业银行不良资产的现状与治理对策

不良资产问题是困扰全球银行业的一个难题。事实上，不良资产问题是商业银行经营发展中不可避免的时常要遇到的问题，许多国家为化解银行不良资产进行了长期、艰苦的探索。当前，我国的银行业同样面临着不良资产比例过高、处置艰难的障碍。由于不良资产问题事关金融体系的稳定，事关国家经济的发展和社会稳定，而且极大地制约了银行的信贷投放能力和积极性，因此，面对不良资产形成与处置中的困难与问题，从研究不良资产在制度、法律、社会信用及银行自身的组织及管理机制出发，探索符合我国国情的银行不良资产的化解途径和办法，具有十分重要的现实意义。     

The Original Maturity of Corporate Bonds: The Influence of Credit Rating,Asset Maturity,Security, and Macroeconomic Conditions

We examine the determinants of the new issue maturity of corporate bonds. As credit rating decreases, new bond issues have longer maturities, but substantial variation in maturity within each rating class remains. We seek to explain the variation of new issue maturity within credit classes. We find that asset maturity, security covenants, and macroeconomic conditions influence the new issue maturity of bonds within rating categories.
