现行金融风险测度方法的局限及其突破 总被引:2,自引:0,他引:2
均值-方差、线性相关系数、VaR等现行金融风险测度方法应用得十分广泛,但应该注意的是在测度风险时必须考虑是否具备必要的前提条件。如果滥用就会导致荒唐的结果.将此作为控制风险的依据可能会带来重大的经济损失。对新的金融风险测度的研究从1997年开始获得了巨大发展.与现行金融风险测度方法相比至少有两大突破:可测度有极端事件分布的风险与更准确描述多变量分布的相关性。 相似文献

现有的控制权私益测度方法本质上都是以控制权获取成本为计量基础的,它是一种间接的测度方法,其理论依据存在缺陷,实际运用也面临挑战。构建控制权私益的直接的估算模型是创新性的课题,既要有科学的思路,又要有相关的实证研究提供数据上的支持。 相似文献

Improved estimation of the covariance matrix of stock returns with an application to portfolio selection 总被引:3,自引:0,他引:3
This paper proposes to estimate the covariance matrix of stock returns by an optimally weighted average of two existing estimators: the sample covariance matrix and single-index covariance matrix. This method is generally known as shrinkage, and it is standard in decision theory and in empirical Bayesian statistics. Our shrinkage estimator can be seen as a way to account for extra-market covariance without having to specify an arbitrary multifactor structure. For NYSE and AMEX stock returns from 1972 to 1995, it can be used to select portfolios with significantly lower out-of-sample variance than a set of existing estimators, including multifactor models. 相似文献

Empirical estimates of monetary policy reaction functions feature a very high estimated degree of monetary policy inertia. This evidence is very hard of reconcile with the alternative evidence of low predictability of monetary policy rates. In this paper we examine the potential relevance of the problem of weak instruments to correctly identify the degree of monetary policy inertia in forward-looking monetary policy reaction function of the type originally proposed by Taylor [1993. Discretion versus policy rules in practice. Canergie-Rochester Conference Series on Public Policy, 39, 195–214]. After appropriately diagnosing and taking care of the weak instruments problem, we find an estimated degree of policy inertia which is significantly lower than the common value in the empirical literature on monetary policy rules. 相似文献

This study explores accounting for shrinkage in continuous flow industries, an area which has received no attention in the literature, but which appears to present some difficulty to cost accountants in some companies studied. The study presents an appropriate approach for process cost accounting where the materials in process undergo some dimensional transformation but remain measurable in the same physical units as the raw materials. Appropriate formulae are presented to help calculate the equivalent units of finished output that the semi-processed materials in inventory represent. The initial development assumes a uniform loss rate, an assumption later relaxed to illustrate the solution procedure for non-uniform loss rates. 相似文献

We consider a joint distribution that decomposes asset returns into two independent components: an elliptical innovation (Gaussian) and a systematic non-elliptical latent process. The paper provides a tractable approach to estimate the underlying parameters and, hence, the assets’ exposures to the latent non-elliptical factor. Additionally, the framework incorporates higher-order moments, such as skewness and kurtosis, for portfolio selection. Taking into account estimation risk, we investigate the economic contribution of the non-elliptical term. Overall, we find weak empirical evidence to support the inclusion of the non-elliptical term and, hence, the higher-order comoments. Nonetheless, our findings support the mean–variance (MV) decision rule that incorporates the elliptical term alone. Excluding the non-elliptical term results in more robust mean–variance estimates and, thus, enhanced out-of-sample performance. This evidence is significant among stocks that exhibit a strong deviation from the Gaussian property. Moreover, it is most pronounced during market turmoils, when exposures to the latent factor are highest. 相似文献

The long memory linear ARCH process is extended to a multivariate universe, where the natural cross-product structure of the covariance is generalized by adding two bi-linear terms with their respective parameter. The residuals of the linear ARCH process are computed using historical data and the (inverse square root of the) covariance matrix. Simple measures of quality assessing the independence and unit magnitude of the residual distributions are proposed. The salient statistical properties of the computed residuals are studied for three data sets of size 54, 55 and 330. Both new terms introduced in the covariance help to produce uncorrelated residuals, but the mean residual magnitudes are much larger than one. The large magnitudes of the residuals are due to the exponential decay of the covariance eigenvalues, corresponding to directions with very small fluctuations in the historical sample. Because the postulated properties of the innovations cannot be obtained regardless of the parameter values, subsequent inferences reach a fundamental limitation in a large multivariate universe. 相似文献

本文结合非金融企业影子银行化的形成机制以及中国金融市场发展的特征事实,从“供给侧”和“需求侧”双重视角探究银行竞争如何抑制非金融企业影子银行化。以2003—2019年中国非金融上市企业为研究样本,分析发现,银行竞争能够显著降低非金融企业影子银行化。进一步以放松中小商业银行分支机构市场准入为标志事件构造准自然实验,基于双重差分法的计量结果为识别银行竞争对非金融企业影子银行化的抑制效应提供了稳健的经验证据。机制分析发现,银行业竞争通过弱化“信贷扭曲”和“监管套利”两个维度的作用机制抑制非金融企业影子银行化。异质性分析表明,银行竞争对非金融企业影子银行化的抑制作用在融资约束较高和投资机会较少的样本中尤为明显。 相似文献
