非凸环境下的多元风险测度

Multivariate risk measures in the non-convex setting

Andreas Haier, Ilya Molchanov

摘要:

交易成本模型中的容许位置族是一个随机闭集,在成比例的交易成本情况下是凸的。然而,凸性失效,例如在固定交易成本的情况下或当仅可能进行有限数量的转移时。本文提出了一种基于考虑投资组合的所有选择并检查其中一个是否可接受的思想来度量此类头寸的风险的方法。给出了非凸投资组合风险度量的性质和基本例子。

英文摘要:

The family of admissible positions in a transaction costs model is a random closed set, which is convex in case of proportional transaction costs. However, the convexity fails, e.g. in case of fixed transaction costs or when only a finite number of transfers are possible. The paper presents an approach to measure risks of such positions based on the idea of considering all selections of the portfolio and checking if one of them is acceptable. Properties and basic examples of risk measures of non-convex portfolios are presented.
