圆锥市场模型的集值风险度量
Set-valued risk measures for conical market models
摘要:
定义了圆锥市场模型的$L^p_d$与$0 \leq p \leq \infty$上的集值风险测度,给出了原始和对偶表示结果.集合的初始禀赋,允许超对冲的多元索赔,形成一个集值次线性(相干)风险度量的值。具有多个合格资产的标量风险度量也是集值框架中的一个特例。
英文摘要:
Set-valued risk measures on $L^p_d$ with $0 \leq p \leq \infty$ for conical market models are defined, primal and dual representation results are given. The collection of initial endowments which allow to super-hedge a multivariate claim are shown to form the values of a set-valued sublinear (coherent) risk measure. Scalar risk measures with multiple eligible assets also turn out to be a special case within the set-valued framework.
