摘要
利用正倒向随机微分方程,建立连续时间框架下的新凯恩斯模型,并将最优货币政策问题转化为带控制约束的随机最优控制问题.结合最大值原理,得到最优货币政策的必要条件,并刻画最优货币政策的特征.
Abstract
In this paper,we give the continuous time version of the New Keynesian model,which is a backward stochastic differential system and translate the optimal monetary policy problem into a stochastic optimal control problem under control constraints.By using the maximum principle for the control system,we obtain the necessary condition for the optimal monetary policy.Also we give the expression of the optimal monetary policy.
