本文将动态控制问题从风险中性扩展到风险厌恶。我们通过一致和充分地嵌套一致的风险衡量标准,为连续的风险厌恶决策设定了一个限度。该方法为研究连续时间的多阶段最优控制问题提供了新的视角。对于极限情况,我们阐述了一种新的动态规划原理,即风险厌恶,并通过推广无穷小生成元给出了风险厌恶的Hamilton-Jacobi-Bellman方程。在此基础上,我们给出了基于倒向随机微分方程的动态风险度量-的一种动态风险度量的建设性解释。
This paper extends dynamic control problems from a risk-neutral to a risk-averse setting. We establish a limit for consecutive risk-averse decision making by consistently and adequately nesting coherent risk measures. This approach provides a new perspective on multistage optimal control problems in continuous time. For the limiting case, we elaborate a new dynamic programming principle, which is risk averse, and give risk-averse Hamilton–Jacobi–Bellman equations by generalizing the infinitesimal generator. In doing so, we provide a constructive explanation of the driver g in g-expectation, a dynamic risk measure based on backward stochastic differential equations.
