利率变动对股价指数影响的实证分析

一、利率对股价影响的主要机制 对于股价的影响最敏锐者莫过于金融因素。在各种金融因素中,利率水准的变动对股价的影响又最为直接和迅速。一般来讲,利率和股价之间具有负相关的关系。 1.货币资金进入股市的主要渠道是信贷资金、储蓄分流及现金方式的社会游资。资金是流动的,资金为追求收益最大化,总是向收益高的市场流动,居民储蓄存款和社会游资进入股市的直接动力在于股市相对收益的高低,而股市相对收益的大小又与利率水准紧密关联。利率降低,表明货     

同业拆借市场与股票市场关系的实证

我国股市属于新兴市场,股市波动较大,市场效率不高,表现为一定程度上的资金拉动型.股票价格取决于未来收益和贴现率,其中影响股票收益的很重要的一个因素是利率.在我国市场化程度最高的是同业拆借市场利率,因此同业拆借市场就成为联接货币市场的重要通道.研究两者之间的互动关系,不仅有助于解释股市收益与波动,而且关系到货币政策如何影响同业拆借市场和股票市场,进而影响到货币政策效力的发挥.     

我国股市发展与经济增长关系的实证分析

几乎所有的教科书都认为,股价走势与宏观经济状况具有密切的关系,宏观经济变量是股票价格变动的重要因素之一,而股市是经济运行的"晴雨表",股市走势总是以一定的时间提前量领先于经济总量的变动趋势.然而,股市与宏观经济的关系是否存在上述逻辑还存在着相当大的争议,这可以从下面国内外研究综述中发现.……     

中国的股票价格对GDP与CPI预测能力的实证检验

文章从股票价格的情报内含角度出发,分析了股票价格是否应纳入货币政策目标体系以及央行是否应对股票价格的变动做出反应。实证结果表明,股价变动的信息内涵无助于提供未来经济活动和物价变动的有用信息,因此,中央银行对股市的态度只能是关注而非盯住,股票价格的变动不应纳入央行的反应函数。     

连续降息储蓄缘何不降温

从1996年5月1日起，央行已连续五次降息，主要目的是为拉动消费，刺激投资。那么其作用如何呢？让我们首先来分析萧山市以下一组数字。从上表可以看出，随着利率的逐步下调，居民储蓄存款热情不减，储蓄水平以月平均增幅1．77％的速度稳步增长。存款利率一再下调，人们为什么仍     

利率变动对股票价格的影响——基于CAPM的分析

现有理论研究多从资金流向和资金使用成本两个角度出发,认为利率上升将导致公司股价下跌。然而从中美资本市场对于加息的实际反应来看,都不完全支持这一结论。本文以资本资产定价模型(CAPM)为基础,考虑利率对股价的影响途径,为解释利率与股价变动的相互关系提供一种新的思路。     

国债利率结构的动态分析与思考

文章通过动态追踪１９９８ 年１ —８ 月国债收益率曲线的变动得出以下结论：一是蝴蝶型变动偏多表明较为严重的市场分割,并对运用欠期技术规避风险产生影响。二是１９９８ 年的数次降息是影响利率结构变动的主要因素,但每次降息对利率结构有不同的作用方式。三是新国债发行的示范效应大于挤占效应。四是利率结构的波动特征对运用财政货币政策实施宏观调控有重要的参考价值     

我国股市非确定性计量问题探析

一、股市不确定性的存在早在１００多年前,道氏理论就提出股市价格有三种趋势,即基本趋势、次级运动和日常波动,这被人们公认是确定的。但直至今天,我们能确切地观察到的,这仅仅是三种趋势混合在一起的总趋势,而无法把它们确切地具体地分离出来。利率的下调将导致股票价格的上升,但具体什么时候上升,上升多少,又是不确定的。确定问题与不确定问题缠扰在一起,导致了信息的混沌,从而形成了股市的不确定性。股市的确定因素与不确定因素早为经济学家和广大股民所注意,他们对确定性进行了大量的、深入的研究,并建造了一系列的数学模…     

利率互换套期保值研究

一、引言随着中国利率市场化进程的推进,中央银行逐步放松和取消对利率的管制,由市场资金供求关系来决定利率水平。利率市场化使利率的波动更加频繁,可预测度降低,利率风险成为金融风险中最基本的风险。商业银行、养老保险基金等定息债券的机构投资者对利率变动的影响非常敏感,     

我国股市波动的利率效应

股票的价格取决于股票的供给和需求,而股票的供求则深受利率影响.利率高,股票供给增加,需求降低,股票价格下跌,这就是股市的利率效应.通过实证分析,我们却发现我国股市的利率效应并不显著,这可归因于三个制度性因素.     

On the experience of projecting the family composition of the population of the USSR

The joint efforts in the USSR by the Central Planning Commission and the State Statistical Commission to develop projections of family characteristics of the Soviet population are described. The projections, based on official data for the rural and urban populations in 1987, are for the years 1991, 1996, 2001, and 2006.     

Estimation of the parameter in the problem of the nile

Estimation of the parameter in the problem of the Nile is treated as a decision problem with squared error loss, It is shown that the minimum risk scale equivariant estimator dominates the incomplete sufficient unbiased estimators considered by Iwase and Seto, Sharper bounds for the equivariant estimator are derived which may be used to obtain the values of the same from the sample with sufficient accuracy.     

Demographic policy in the light of the resolutions of the Twenty-sixth Congress of the Communist Party

The USSR is moving from extensive to intensive type of population reproduction, not because of any governmental measures but as a reaction to objective circumstances. At present there is a reduction in the population cohort of working age. This has an adverse effect on production. And the number of the elderly is increasing; we must involve them more in the production process, in monitoring the service sphere, for instance. The infant mortality rate has declined sharply in the USSR, especially since World War II. The birthrate has also dropped, but it is still higher than in the US, France, or West Germany. Some authorities think that this (the ZPG) is a good idea, but this author thinks it is a bad idea, meaning a drop in society's productive forces. We need an active demographic policy, meaning one which ensures optimal reproduction of the population with an improvement in its health, culture, and living standard. The policy must be differentiated, as conditions vary from one part of the country to another. An example is the 1981 decree on assistance to families with children which provides for payments of 35-50 rubles/month to mothers who must stay home to look after children. The number of children per family to ensure reproduction must be 2.6 on the average. In the Central Asian republics family sizes of 4-5 children are anticipated, but in the RSFSR, Ukraine, Belorussia, and the Baltic republics the anticipated size of families is rather low. Measures must be taken to alter this by providing assistance to families with children.

On the Computation of the Distribution for the Analysis of Means

Abstract

We discuss the accuracy of the computation and present a fortran program to compute the cumulative distribution function (CDF) for the analysis of means (ANOM).     

On the behavior of mle of the scale parameter of the student family

This paper contains a study of the qualitative properties of the maximum likelihood estimate of the scale parameter of the Student family as a function of its (continuous) degrees of freedom. Sharp bounds are provided for the estimate and its (continuous) degrees of freedom. Sharp bounds are provided for the estimate and its monotonicity as a function of the degrees of freedom is established. Inferential implications are also discussed.     

On the estimation of the parameters of the von mises distribution

The usual maximum likelihood estimators of the parameters of the von Mises distribution are shown to perform badly in small samples. In view of this and the fact that these estimators require a large amount of computation, alternative, simpler estimators are proposed. It is shown that these estimators are at least comparable to the traditional estimators and are, in many cases, superior to them. We also apply the procedure of jackknifing to the maximum likelihood estimator of the concentration parameter of the von Mises distribution and compare the properties of the jackknifed estimator with the other estimators considered in this paper.     

On the admissibility of the maximum-likelihood estimator of the binomial variance

This paper addresses the admissibility of the maximum-likelihood estimator (MLE) of the variance of a binomial distribution with parameters n and p under squared-error loss. We show that the MLE is admissible for n ≤ 5 and inadmissible for n≥ 6.
