Taylor Rules in a Model that Satisfies the Natural-Rate Hypothesis
分析了央行利率政策规则不导致经济实际不确定性的条件，在灵活价格和粘性价格模型中，发现粘性价格模型实现实际确定性的充要条件是相应灵活价格模型具有名义和实际确定性，这要求泰勒规则对滞后通胀率做出激进反应。
The authors analyze the restrictions necessary to ensure that the interest-rate policy rule used by the central bank does not introduce real indeterminacy into the economy. They conduct this analysis in a flexible price economy and a sticky price model that satisfies the natural rate hypothesis. A necessary and sufficient condition for real determinacy in the sticky price model is that there must be nominal and real determinacy in the corresponding flexible price model. This arises if and only if the Taylor rule responds aggressively to lagged inflation rates.
