We explore Knightian model uncertainty as an explanation for the observed excess persistence and attenuation in estimated interest-rate reaction functions for the United States, relative to what optimal feedback rules would suggest. Two types of uncertainty are identified: (i) unstructured model...

This paper explores Knightian model uncertainty as a possible explanation of the considerable difference between estimated interest rate rules and optimal feedback descriptions of monetary policy. We focus on two types of uncertainty: (i) unstructured model uncertainty reflected in additive...

This paper considers the "Lucas"-critique issue of how the indicator role of auction prices is affected when the central bank attempts to exploit the correlation between auction prices and inflation. This question is examined using a simple macroeconomic model with rational expectations (perfect...

This paper analyses the mechanics of simple interest rate rules for two models----one with backward and the other with forward looking, rational expectations. The approach is to consider policy when faced with a specific task reducing inflation in a stabilizing manner. The two models are: (i)...

An issue with monetary policy rules to guide inflation is the indeterminacy of the price level. In the context of a traditional backward-looking and a modern forward-looking New-Keynesian Phillips curve, this paper examines the dynamic and steady state properties of interest rate rules anchored...

This paper examines the properties of interest rate rules aimed at controlling aggregate price inflation. Policies are compared in two models having either flexible or sticky inflation The latter is assumed to derive from a traditional, adaptive-expectations augmented Phillips curve. The...
