英文摘要:
In this work we consider optimal stopping problems with conditional convex risk measures called optimised certainty equivalents. Without assuming any kind of time-consistency for the underlying family of risk measures, we derive a novel representation for the solution of the optimal stopping problem. In particular, we generalise the additive dual representation of Rogers (2002) to the case of optimal stopping under uncertainty. Finally, we develop several Monte Carlo algorithms and illustrate their power for optimal stopping under Average Value at Risk.

中文摘要:
在这项工作中,我们考虑了具有条件凸风险度量的最优停止问题,称为优化确定性等价物。在不假设潜在风险度量族的任何时间一致性的情况下,我们推导出了最优停止问题的一种新表示。特别地,我们将Rogers(2002)的加法对偶表示推广到不确定性下的最优停止情况。最后,我们开发了几种蒙特卡罗算法,并说明了它们在平均风险值下的最优停止能力。
