商业银行利率风险计量模型及实证分析--非平移收益曲线条件下的随机免疫策略

传统的久期理论建立在收益曲线平移等严格假设条件上，因而其在实践中的有效性大大降低了。根据Markowitz（1959）等理论可推导出：资产价格的总风险包括收益的方差和全久期向量两部分；假若商业银行采取现金中性（cash neutrality）的资产交易策略，风险计量模型可转换为线性规划问题，从而可以构建基于利率风险最小化模型的随机免疫策略。也就是说，引入随机免疫的理念来替代经典的免疫理论，通过实证分析得出：无现金交易条件下的随机免疫策略能够降低利率风险。     

Strategic Firm Behavior Under Average-Revenue-Lagged Regulation

Price caps have been shown to have incentive properties superior to traditional rate of return regulation. Average-revenue-lagged regulation (ARL) is attractive in that steady-state prices are known to be efficient. We show that the ARL scheme can be manipulated by the firm so as to yield the unregulated global profit maximum. While tests exist that can provide the regulator with evidence of this strategic behavior, we also demonstrate that the unregulated global profit maximum will not be attainable if Laspeyres (L) regulation is employed.Jel classification: L43, L51I would like to thank Michael Crew and an anonymous referee for their extremely helpful suggestions.     

The Lévy LIBOR model

Models driven by Lévy processes are attractive because of their greater flexibility compared to classical diffusion models. First we derive the dynamics of the LIBOR rate process in a semimartingale as well as a Lévy Heath-Jarrow-Morton setting. Then we introduce a Lévy LIBOR market model. In order to guarantee positive rates, the LIBOR rate process is constructed as an ordinary exponential. Via backward induction we get that the rates are martingales under the corresponding forward measures. An explicit formula to price caps and floors which uses bilateral Laplace transforms is derived.

宏观利率政策的有效性研究

宏观利率政策对经济增长具有有效性。尽管我国几次调整利率的效果不如预期那么好 ,但否定货币政策在我国已失去作用的看法是错误的。从IS -LM分析可以看出货币政策的有效性 ,但其有效性受着一些因素的约束。为此 ,必须有适当的政策促进利率政策的有效性。

An Analysis of the Deposit-taking Market of Hong Kong

This paper analyzes the deposit-takingmarket in Hong Kong prior to the deregulation ofinterest rates in 1994. We argue that bankingregulations, in the forms of branching restrictionsand interest-rate ceilings, had created amonopsonistic market for short-term bank deposits. Asa result, banks in Hong Kong had earned asubstantially wider interest-rate margin than banks inother Asia-Pacific countries and the United States. We provide procedures to estimate the economicsignificance of the foregone interest and find themonopsonistic rent to be in the order of 1% of theGross Domestic Product of Hong Kong for the period1987 through 1994.     

近期债券市场基本面分析与展望

该文认为，外需放缓导致国内经济增速放缓，年内通货膨胀将呈前高后低走势，1季度将成为通胀高点，加息概率依然较大，短期内债券市场将维持当前的震荡格局，但仍不失资金配置良机，相对而言，长期国债，短期融资券的投资价值较大。     

Has International Financial Integration Increased?

This paper compares the behavior of real interest rate differentials across the major countries under the Bretton Woods regime and the regime of floating exchanges that replaced it. The primary object is to investigate both the extent of market integration and its changes over time. For all fifteen possible country pairs real interest differentials are mean reverting, and in two-thirds of these cases indistinguishable from zero statistically. For all country pairs on average and for most such pairs individually, moreover, the estimated differentials are not appreciably different in absolute value than the differentials that we estimate for various money-market rates within the United States. Additional evidence points to a narrowing of differentials under floating rates over time and an increase in speeds of convergence.     

THE TERM STRUCTURE OF INTEREST RATES AS A GAUSSIAN RANDOM FIELD

A simple model of the term structure of interest rates is introduced in which the family of instantaneous forward rates evolves as a continuous Gaussian random field. A necessary and sufficient condition for the associated family of discounted zero-coupon bond prices to be martingales is given, permitting the consistent pricing of interest rate contingent claims. Examples of the pricing of interest-rate caps and the situation when the Gaussian random field may be viewed as a deterministic time change of the standard Brownian sheet are discussed.
