DID U.S. MONETARY POLICY RESPOND TO EXCHANGE RATES, LONG-TERM INTEREST RATES, AND THE UNEMPLOYMENT RATE GAP?

Abstract

Extending the original Taylor rule and applying the VAR model, the author finds that the federal funds rate (FFR) responds positively to a shock to the output gap, the inflation gap, the long-term interest rate, or the lagged FFR, and it reacts negatively to a shock to the unemployment rate gap or the exchange rate. The response of FFR to stock prices is insignificant at the 5% level. The long-term rate can explain up to 41.3% or 46.1% of the variation in FFR, depending on the model considered. The exchange rate can explain up to 8.5% or 12.3% of the variance, depending on the model considered. The output gap can explain up to 26.6% of FFR variance. The unemployment rate gap can explain up to 26.8% of the variation in FFR. Because FFR responds to a shock to the output gap and the unemployment rate gap in a similar manner, both may be considered in conducting monetary policy. The more explanatory power of the long-term interest rate than the inflation gap may suggest that both need to be taken into consideration in the Taylor rule.
