摘要
利用消费决策模型研究了风险规避下的随机现金流管理问题,得到了该问题的最优策略,同时证明了指数效用函数下决策者的最优策略与风险中性时决策者的最优策略具有相同的结构.
In this paper,we propose a framework for incorporating risk aversion in stochastic cash management problem.We characterize the structure of the optimal policy on the risk-averse stochastic cash management problem according to the consumption model,and show that the structure of the optimal policy for a decision maker with exponential utility functions is almost identical to that of the optimal policy for the risk-neutral model.
