Accurate measurement of bank risk is a matter of considerable importance for bank regulation and supervision. Current … practices in most countries emphasize reliance on financial statement data for assessing banks’ risk. However, the possibility … of increased reliance on market-based risk indicators has been a topic for academic and regulatory debate for a long time …

Using coherent measures of risk the sum of the capital requirements of the divisions is larger than the … jointly satisfy three natural fairness requirements for allocating risk capital in illiquid markets: Core Compatibility, Equal … Treatment Property and Strong Monotonicity. Core Compatibility can be viewed as the allocated risk to each coalition (subset) of …

A new class of risk measures called cash sub-additive risk measures is introduced to assess the risk of future … sub-additive risk measures can model stochastic and/or ambiguous interest rates or defaultable contingent claims …. Practical examples are presented and in such contexts cash additive risk measures cannot be used. Several representations of the …

The measurement and the allocation of risk are fundamental problems of portfolio management. Coherent measures of risk … provide an axiomatic approach to the former problem. In an environment given by a coherent measure of risk and the various … portfolios' realization vectors, risk allocation games aim at solving the second problem: How to distribute the diversification …

Coherent measures of risk defined by the axioms of monotonicity, subadditivity, positive homogeneity, and translation … invariance are recent tools in risk management to assess the amount of risk agents are exposed to. If they also satisfy law … invariance and comonotonic additivity, then we get a subclass of them: spectral measures of risk. Expected shortfall is a well …
