RiskRank：测量相互关联的风险
RiskRank: Measuring interconnected risk
摘要：
本文提出RiskRank作为周期性和横截面系统性风险的联合度量。RiskRank是一个通用的聚合运算符，同时考虑各个实体的风险水平及其相互关联性。该措施依赖于将系统性风险分解为子组成部分，然后使用一套风险措施及其关系进行评估。出于这个目的，出于Choquet积分的发展，我们采用RiskRank函数来聚合风险度量，允许在聚合过程中整合不同因素的相互关系。RiskRank的使用是通过一个真实世界的情况下，在欧洲的设置，我们表明，它表现良好，在样本分析。在这个例子中，我们提供了一个估计的系统性风险，从国家层面的风险和跨境联系。
英文摘要：
This paper proposes RiskRank as a joint measure of cyclical and cross-sectional systemic risk. RiskRank is a general-purpose aggregation operator that concurrently accounts for risk levels for individual entities and their interconnectedness. The measure relies on the decomposition of systemic risk into sub-components that are in turn assessed using a set of risk measures and their relationships. For this purpose, motivated by the development of the Choquet integral, we employ the RiskRank function to aggregate risk measures, allowing for the integration of the interrelation of different factors in the aggregation process. The use of RiskRank is illustrated through a real-world case in a European setting, in which we show that it performs well in out-of-sample analysis. In the example, we provide an estimation of systemic risk from country-level risk and cross-border linkages.
