摘要翻译:
当基于动态风险度量的决策受到移动视界的影响时,我们考虑了投资组合选择,以及这可能造成的不一致。通过给出时间一致性的一种形式处理,它独立于Bellman方程,我们表明存在一种新的意义,在这种意义上,这些决策可以被看作是一致的。

英文摘要:
We consider portfolio selection when decisions based on a dynamic risk measure are affected by the use of a moving horizon, and the possible inconsistencies that this creates. By giving a formal treatment of time consistency which is independent of Bellman's equations, we show that there is a new sense in which these decisions can be seen as consistent.
