To overcome several limitations of existing diversification indices, we introduce the quotient (DQ). Defined through a parametric family risk measures, DQ satisfies three natural properties, namely, non-negativity, location invariance and scale invariance, which are shown to be conflicting for any traditional index based on single measure. We pay special attention two most important classes mea...

To present essential and pragmatic lessons for other countries which are still in pandemic to prepare future affections diseases, risk mitigation measures took by Chinese government during the COVID-19 period were assorted included. Pertinent information was arranged three parts, pre-pandemic, during-pandemic after-pandemic. In first period, stockpile building, public health workforce training ...

Abstract In this paper we present results on dynamic multivariate scalar risk measures, which arise in markets with transaction costs and systemic risk. Dual representations of such measures are presented. These then used to obtain the main time consistency; namely, an equivalent recursive formulation multiportfolio consistency. We motivated study consistency as superhedging measure (with a sin...
