我国商业银行利率风险度量模型的现实选择

随着利率市场化的推进,利率风险上升为银行的主要风险,利率风险管理成为商业银行风险管理的重点.利率风险度量是进行利率风险管理的基础,因此选择合适的利率风险度量模型具有积极意义.本文试从我国商业银行的利率风险状况出发,说明了利率风险管理尤其是利率风险度量的重要性,分析了利率敏感性缺口模型、久期模型和模拟法三类主要的利率风险度量模型及其利弊.最后结合成本收益原则以及我国现实约束条件,推理出我国商业银行短期内应逐步建立起以久期模型为主,利率敏感性缺口模型为辅的利率风险度量管理体系;长期内应大力创造条件,实现以模拟法度量利率风险.     

Contracting and Reporting Conservatism around a Change in Fiduciary Duties*

We exploit an influential 1991 Delaware court ruling to examine simultaneously two types of conservatism that play important roles in resolving creditor–owner agency conflicts: contracting conservatism and reporting conservatism. The ruling expanded managerial fiduciary duties in favor of creditors for Delaware-incorporated firms in the vicinity of insolvency. In those firms, following the ruling, debt contracts are less likely to include conservative adjustments to accounting numbers used for covenant compliance (i.e., contracting conservatism decreases), while public financial reporting becomes more conservative (i.e., reporting conservatism increases). The decrease in contracting conservatism is concentrated in firms that exhibit a greater increase in reporting conservatism, suggesting that reporting conservatism is more cost-effective in resolving agency conflicts. In addition, the substitution effect is more pronounced in firms facing greater business uncertainty and firms with greater board independence.     

When Do Qualitative Risk Disclosures Backfire? The Effects of a Mismatch in Hedge Disclosure Formats on Investors' Judgments

Disclosure standards mandate the quantitative disclosure of hedging‐instrument‐related risks but not the disclosure of hedged‐item‐related risks. We examine how a match (mismatch) in formats, caused by making quantitative (qualitative) hedged item disclosures alongside quantitative hedging instrument disclosures, affects investors' integration of information from these two related disclosures. Our first experiment varies the hedged item disclosure format (quantitative or qualitative) and the portion of risk hedged (small or large). We find that when disclosure formats are mismatched, the less comparable nature of the two disclosures caused investors to neglect the offsetting relationship when assessing net risks. As a result, risk and investment judgments were influenced by the more prominent quantitative hedging instrument disclosures. Our second experiment finds that the use of a qualitative debiaser that clarifies the relationship between the two disclosures led to the integration of information and mitigated this effect.     

企业价值转移和资本结构:一项实证分析

本文选取2001年沪深A股677家上市公司的市场和财务数据,首先检验两个指标是否具有显著相关性:市值规模比和长期负债比率。并按价值转移理论,利用市值规模比把677家上市公司划分为三组:价值流入期、价值稳定期和价值流出期。实证研究处于不同价值转移阶段企业资本结构的特点。
