The framework of this paper is that of uncertainty, that is when no reference probability measure is given. To every convex regular risk measure $\rho$ on ${\cal C}_b(\Omega)$, we associate a canonica...
This paper gives an overview of the theory of dynamic convex risk measures for random variables in discrete time setting. We summarize robust representation results of conditional convex risk measures...
Risk assessment for uncertain cash flows: Model ambiguity, discounting ambiguity, and the role of bubbles
Risk assessment uncertain cash flows Model ambiguity

We study the risk assessment of uncertain cash flows in terms of dynamic convex risk measures for processes as introduced in Cheridito, Delbaen, and Kupper (2006). These risk measures take into accou...
We analyze operational risk in terms of a spin glass model. Several regimes are investigated, as a functions of the parameters that characterize the dynamics. The system is found to be robust against...

It is commonly accepted that Commodities futures and forward prices, in principle, agree under some simplifying assumptions. One of the most relevant assumptions is the absence of counterparty risk. I...
