范围风险价值:多变量和极值

Range Value-at-Risk: Multivariate and Extreme Values

Roba Bairakdar, Lu Cao, Melina Mailhot

摘要:

由Cont等人(2010)提出的单变量范围风险价值的概念在多维环境中得到了扩展。传统的风险度量方法在处理重尾分布和无穷尾期望时不太适用。本文给出了稳健截尾期望的多元定义,克服了这一问题。鲁棒性和其他属性以及经验估计。在极值框架下的封闭形式的表达式和特殊情况进行了讨论。数值和图形的例子来检查经验估计的准确性。

英文摘要:

The concept of univariate Range Value-at-Risk, presented by Cont et al. (2010), is extended in the multidimensional setting. Traditional risk measures are not well suited when dealing with heavy-tail distributions and infinite tail expectations. The multivariate definitions of robust truncated tail expectations are provided to overcome this problem. Robustness and other properties as well as empirical estimators are derived. Closed-form expressions and special cases in the extreme value framework are also discussed. Numerical and graphical examples are provided to examine the accuracy of the empirical estimators.
