摘要翻译：
根据Cheridito、Delbaen和Kupper(2006)中引入的过程的动态凸风险度量，我们研究了不确定现金流的风险评估。这些风险度量不仅考虑到现金流的金额，还考虑到现金流的时间。在可选的sigma域上，我们用适当惩罚概率测度讨论了它们的鲁棒表示。这就产生了对模型和贴现歧义的明确分析。我们关注不同时间一致性概念的上鞅准则。特别地，我们展示了在动态惩罚中如何出现泡沫，以及它们如何导致风险评估程序的渐近安全性崩溃。

英文摘要：
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 account not only the amounts but also the timing of a cash flow. We discuss their robust representation in terms of suitably penalized probability measures on the optional sigma-field. This yields an explicit analysis both of model and discounting ambiguity. We focus on supermartingale criteria for different notions of time consistency. In particular we show how bubbles may appear in the dynamic penalization, and how they cause a breakdown of asymptotic safety of the risk assessment procedure.
