Cont et al. recently showed that coherent risk measures are not robust with respect to changes in large data. In this paper we show that robust risk measures always generate pathological financial positions called "Good Deals". We also introduce the minimal distribution invariant modification of...

In this paper, we consider the problem of optimal reinsurance design, when the risk is measured by a distortion risk measure and the premium is given by a distortion risk premium. First, we show how the optimal reinsurance design for the ceding company, the reinsurance company and the social...

In this paper we consider the problem of optimal reinsurance design for general distortion risk measures and premiums. In the first part of the paper, we find the Lagrangian dual of the primal optimal reinsurance problem and show the strong duality holds. Therefore we characterize the optimal...
