In this paper, we study the structure of optimal contracts in a banking system when there is no risk of moral hazard. We consider a risk management problem under a policy that reduces the excessive risk taking behavior by making all banks bear part of the risk that they transfer to other parties...

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...
