英文摘要:
In this paper we propose the notion of dynamic deviation measure, as a dynamic time-consistent extension of the (static) notion of deviation measure. To achieve time-consistency we require that a dynamic deviation measures satisfies a generalised conditional variance formula. We show that, under a domination condition, dynamic deviation measures are characterised as the solutions to a certain class of backward SDEs. We establish for any dynamic deviation measure an integral representation, and derive a dual characterisation result in terms of additively $m$-stable dual sets. Using this notion of dynamic deviation measure we formulate a dynamic mean-deviation portfolio optimisation problem in a jump-diffusion setting and identify a subgame-perfect Nash equilibrium strategy that is linear as function of wealth by deriving and solving an associated extended HJB equation.

中文摘要:
在本文中,我们提出了动态偏差度量的概念,作为偏差度量(静态)概念的动态时间一致性扩展。为了实现时间一致性,我们要求动态偏差度量满足广义条件方差公式。我们证明了在控制条件下,动态偏差测度被刻画为一类向后SDE的解。我们为任何动态偏差度量建立了一个积分表示,并导出了一个关于附加$m$-稳定对偶集的对偶特征化结果。利用动态偏差测度的概念,我们在跳跃-扩散环境下建立了一个动态均值-偏差投资组合优化问题,并通过推导和求解相关的扩展HJB方程,确定了一个与财富成线性函数的子博弈完美纳什均衡策略。
