Stochastic Orders and Risk Measures: Consistency and Bounds
We investigate the problem of consistency of risk measures with respect to usual stochastic order and convex order. It is shown that under weak regularity conditions risk measures are consistent with these stochastic orders. This result is used to derive bounds for risk measures of portfolios. As a by-product, we extend the characterization of Kusuoka (2001) of coherent, law-invariant risk meas...
متن کاملRisk Measures with Comonotonic Subadditivity or Convexity and Respecting Stochastic Orders
In Song and Yan (2006), we introduced risk measures which are comonotonic subadditive or comonotonic convex, and gave their representations in terms of Choquet integrals. Independently, Heyde et al. (2006) proposed a data based risk measure in which the comonotonic subadditivity is taken as an axiom. The present paper proposes an axiomatic approach to some new risk measures and gives their repr...

15 صفحه اولDual stochastic dominance and quantile risk measures
Following the seminal work by Markowitz, the portfolio selection problem is usually modeled as a bicriteria optimization problem where a reasonable trade-off between expected rate of return and risk is sought. In the classical Markowitz model, the risk is measured with variance. Several other risk measures have been later considered thus creating the entire family of mean-risk (Markowitz type) ...
متن کاملStochastic Shortest Paths and Risk Measures
We consider three shortest path problems in directed graphs with random arc lengths. For the first and the second problems, a risk measure is involved. While the first problem consists in finding a path minimizing this risk measure, the second one consists in finding a path minimizing a deterministic cost, while satisfying a constraint on the risk measure. We propose algorithms solving these pr...
