متن کاملReducing model risk via positive and negative dependence assumptions
We give analytical bounds on the Value-at-Risk and on convex risk measures for a portfolio of random variables with fixed marginal distributions under an additional positive dependence structure. We show that assuming positive dependence information in our model leads to reduced dependence uncertainty spreads compared to the casewhere onlymarginals information is known. Inmore detail, we show t...
