Risk Measures , Risk Aggregation and Capital Allocation
We consider risk measures, risk aggregation and capital allocation in these lecture notes and build on our earlier introduction to Value-at-Risk (VaR) and Expected Shortfall (ES). We will follow Chapter 8 of the 2 edition of Quantitative Risk Management by MFE quite closely. This chapter, however, contains considerably more material than we will cover and it should be consulted if further detai...
متن کاملCapital requirements, risk measures and comonotonicity
In this paper we examine and summarize properties of several well-known risk measures, with special attention given to the class of distortion risk measures. We investigate the relationship between these risk measures and theories of choice under risk. We also consider the problem of evaluating risk measures for sums of nonindependent random variables and propose approximations based on the con...
متن کاملThe Marginal Cost of Risk, Risk Measures, and Capital Allocation
Financial institutions define their marginal cost of risk on the basis of the gradients of arbitrarily chosen risk measures. We reverse this approach by calculating the marginal cost for a profit-maximizing firm with risk-averse counterparties, and then identifying the risk measure delivering the correct marginal cost. The resulting measure is a weighted average of three parts, each correspondi...

15 صفحه اولRisk Measures , Risk Aggregation and Capital Allocation 2
In 1999 Artzner et al. proposed a list of properties that any good risk measure should have and this list gave rise to the concept of coherent and incoherent measures of risk. Since then a substantial body of research has developed on the theoretical properties of risk measures and we describe some of these results here. Let M denote the space of random variables representing portfolio losses o...
