    Pair-Copula Constructions of Multiple Dependence and Its Application

    随着金融市场的不断发展和创新,金融市场和金融资产之间的相关关系越来越复杂,呈现出非线性、非对称以及尾部相关的相关形式。因此,传统使用的线性相关系数的分析方法早已不能准确地反映金融市场的相关信息。此外,由SKlar提出的copula理论则认为,随机变量之间的相关信息可以用copula函数表达。因此,国内外学者开始利用不同形式的copula函数来表示多元随机变量之间的相关模式,但没有考虑到多元随机变量两两之间服从的分布并非全部一致。基于这一考虑,本文介绍了一种新的方法,即pair-copula方法,不仅允许应用不同的copula函数,更准确地反映不同随机变量之间的相关性,而且可以十分方便地建立联合...With the development of the financial markets, the dependent relationship between financial assets become more and more complicated and represent nonlinear, asymmetric and tail dependence, as well.

    VaR Models in Risk Management: A Comparative Analysis

    Get PDF
    摘要 VaR是一定期限内特定金融资产头寸在一定概率下可能遭受的最大损失。自上世纪九十年代以来,VaR模型由于其度量风险的定量性、综合性、通俗性等特点而被许多金融机构和监管当局广泛使用,逐渐成为金融风险度量的重要基准。而在由美国次贷危机引发的国际金融危机中,很多金融机构因为资产遭受巨大损失而被迫将自身出卖给竞争对手甚至破产。在这种环境下,研究VaR模型在度量风险方面的应用、存在的问题和改进的方向对金融风险管理的实践有着重要的意义。 VaR估计的基础是选择适当的收益率分布。为此,在进行VaR估计之前本文简要介绍了各种收益率和波动率模型并分析了上证综指的收益率和波动率特点,结果发现,上证综指收益...Abstract VaR can be defined as the maximal loss of a financial position during a given time period for a given probability.
