当代新凯恩斯主义货币经济学的新发展

New developments in present-day new Keynesian monetary economics

将垄断竞争和名义刚性假设引入MIU模型,新凯恩斯主义者建立了与AS—IS—LM模型简单线性形式相一致的一般动态均衡模型,实现了基于微观最优行为的动态一般均衡货币理论模型与适用于货币政策分析的线性宏观经济模型的统一,政策分析的重点转向政策目标和工具规则的统一。但是,在政策目标选择,通货膨胀的动态性和政策工具规则设定方面仍未达成共识。

The new Keynesianists have introduced monopoly competition and nominal rigidity hypothesis into MIU Model. They＇ ve also established a general dynamic equilibrium model in line with the simple linear form of AS - IS - LM Model, which unifies the general dynamic equilibrium model of monetary theory based on micro optimal behavior with the linear macro economic model suitable for monetary policy analysis. They＇ ve diverted their policy analysis focus to the unification of the policy objectives and the tool rules. However, they have not reached agreement on the selection of policy objectives and the design of inflation dynamics and tool rules yet.
