风险度量的时间一致性和动态范围

Time consistency and moving horizons for risk measures

Samuel N. Cohen, Robert J. Elliott

摘要:

我们考虑投资组合选择时,基于动态风险度量的决策受到使用移动的地平线,这可能产生的不一致。通过给出一个正式的治疗时间的一致性,这是独立的贝尔曼方程,我们表明,有一个新的意义上,这些决定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.
