一致风险测度的对偶表示

On the Dual Representation of Coherent Risk Measures

Marcus Ang, Jie Sun, Qiang Yao

摘要:

风险测度论中的一个经典结果是:每个相干风险度量都有一个对偶表示,作为风险包络上某个期望值的上确界。我们更详细地研究这个主题。相关问题包括:1.设置风险信封的操作以及它们如何改变风险度量; 2.流行的风险度量的风险包络的结构,3。风险度量的多样性及其对风险包络的影响,以及4。随机最优化中的风险度量与鲁棒最优化中的不确定集之间的联系。

英文摘要:

A classical result in risk measure theory states that every coherent risk measure has a dual representation as the supremum of certain expected value over a risk envelope. We study this topic in more detail. The related issues include: 1. Set operations of risk envelopes and how they change the risk measures, 2. The structure of risk envelopes of popular risk measures, 3. Aversity of risk measures and its impact to risk envelopes, and 4. A connection between risk measures in stochastic optimization and uncertainty sets in robust optimization.
