A GENERAL PROOF OF THE DYBVIG-INGERSOLL-ROSS THEOREM: LONG FORWARD RATES CAN NEVER FALL

A senera1 proof of the Dybvig-Ingersoll-Ross Theorem o n thc monotonicity of long foraard rates is presented. Some inconsistencies in the original proof o f this theorein are discussed.     

我国国际资本流动性程度和非流动性原因的度量与检验--来自中美日三国消费模式对比的经验证据

加入WTO以后,我国的国际资本流动性开始有所加强,流动方式也有所改变。文章选择中国、美国和日本的消费和收入数据,在国家之间实际利率均衡的假设下,通过国家消费模式的考察和对比,发现我国的经济运行并不满足国际资本完全流动性假说,其原因既出于我国资本市场与国际资本市场之间存在进入限制,也出于我国资本市场与国际资本市场的非完全整合。这些经验发现表明,我国经济中的名义利率、汇率和资本市场仍然处于有限管制过程中,必须通过深化国内金融体制改革和逐步实现资本市场开放等有力措施来增强我国国际资本的流动性,进而保持我国快速经济增长和提高整体资源配置效率。     

负债公允价值计量分析

本文从分析面值与现值的关系出发,揭示了负债公允价值计量的实质。在此基础上分析了现行的实际利率法的不足,并提出了新的实际利率法。同时,还探讨了对负债的现值计算的有关问题。     

WHEN IS THE SHORT RATE MARKOVIAN?

We answer this question in the very general context of the n-factor Heath, Jarrow, and Morton model for the evolution of the term structure of interest rates, with nonrandom volatility. the answer is that a constraint is imposed on the behavior of the volatility structure. We explain the importance of this result for the design of efficient numerical algorithms for the valuation of options on the term structure.

Technological Innovations and the Interest Rate

We build a dynamic general equilibrium model that adds a banking sector to the standard RBC model. We look at the response of the real interest rate to innovations in the banks' technology and in the nonbank firms' technology. While technological innovations in the nonbanking sector put upward pressure on the interest rate, technological innovations in banks exert downward pressure on the interest rate. This implies that, if the technological innovations in banks are strong enough, stochastic simulation experiments generate negative correlations between the real interest rate and current and future values of real output. This is especially significant because negative correlations between the interest rate and output are a key post-war U.S. business cycle fact difficult to replicate in benchmark dynamic models.     

企业人力资本产权制度史论解析

按照“利益相关论”的通解，企业所有权安排的“状态依存”的实质意义是要解决“在正常状态下企业所有当事人各拥有多大剩余索取权和控制权以及如何行使”的问题，就公司制股权性质和要求来说，只要所有权主体将其资本要素投入公司而具有不可收回性，并能以投入数额为限承担责任和取得收益回报，那么，人力资本要素就可以“股份化”为股权形式，并拥有余索取权和企业控制权，既是必然合理的又是现实可能的；为了维护和保障人力资本、特别是专业化的人力资本产权权益，应将人力资本所有投到企业的人力资本效产“作资入股”，转化为股权，按照股权平等的原则与公司经营管理和利润分配。     

A Note on the Stability of Lognormal Interest Rate Models and the Pricing of Eurodollar Futures

The lognormal distribution assumption for the term structure of interest is the most natural way to exclude negative spot and forward rates. However, imposing this assumption on the continuously compounded interest rate has a serious drawback: rates explode and expected rollover returns are infinite even if the rollover period is arbitrarily short. As a consequence, such models cannot price one of the most widely used hedging instruments on the Euromoney market, namely the Eurodollar futures contract.
The purpose of this note is to show that the problems with lognormal models result from modeling the wrong rate, namely the continuously compounded rate. If instead one models the effective annual rate these problems disappear.     

中国与印度金融现状比较

由于印度和中国有很多的相似性,这为中国和印度的比较提供了基础。本文主要通过中印两国在金融领域中一些重要方面的比较,如银行体系、资本市场和利率市场化程度来发现中印两国在金融领域中的差异,印度的银行体系相对健全,具有较好的国际信誉;和印度相比,中国的银行体系问题重重。印度在资本市场的数量、结构层次、运行机制,以及融资规模等方面和中国相比存在着很大的优势。印度利率市场化程度高于中国。
