Time consistency and moving horizons for risk measures

Risk Management 2010-07-12 v2 Optimization and Control

Abstract

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.
