We present the first assessment of U.S.monetary policy across time and frequencies within the Taylor Rule framework. We derive a novel wavelet tool - the partial wavelet gain - to estimate a parametric equation relating the federal funds rate to infation and the output gap. We detect a gradual shift of the focus of policy from short cycles to intermediate cycles at the beginning of the Great Moderation,followed by a strengthening of policy´s reaction to long fluctuations once credibility was attained, and, during the Great Recession, a renewed interest in shorter output cycles. We document that the violation of the Taylor principle until the early 1980s and the strengthening of the reaction of policy to inflation there after were more marked at intermediate than at long cycles. Overall, we also detect lead-lag relationships between the policy rate and infation and the output gap that differ along time and cyclical frequencies.
