Stabilising Properties of Discretionary Monetary Policies in a Small Open Economy
在新凯恩斯开放经济模型中证明,开放经济下相机抉择货币政策的稳定性质与封闭经济不同,汇率渠道会削弱国内通胀目标制下应对需求冲击的完美稳定效果。
This article sets out a simple New Keynesian open-economy model and shows that the conduct of discretionary monetary policy in an open economy differs substantially from the closed-economy framework. The article shows analytically that the existence of the direct exchange rate channel in the open economy Phillips Curve impairs the perfect stabilising property of monetary policy in the face of demand-side disturbances under domestic inflation targeting. If CPI inflation is instead the target, then the perfect stabilising property of monetary policy breaks down even in the absence of the direct exchange rate channel in the Phillips Curve.
