Bounds on Choquet Risk Measures in Finite Product Spaces with Ambiguous Marginals

Mario Ghossoub, David Saunders, Kelvin Shuangjian Zhang

We investigate the problem of finding upper and lower bounds for a Choquet risk measure of a nonlinear function of two risk factors, when the marginal distributions of the risk fac…

Wrong-Way Bounds in Counterparty Credit Risk Management

Amir Memartoluie, David Saunders, Tony Wirjanto

We study the problem of finding the worst-case joint distribution of a set of risk factors given prescribed multivariate marginals and a nonlinear loss function. We show that when…
