We use a Taylor rule with time-varying policy coefficients in combination with an unobserved components model for the output gap to estimate the uncertainty about future values of the Federal Funds Rate. The model makes it possible to separate ex-ante interest rate uncertainty into three...

We study how the inclusion of growth rates of monetary aggregates or changes in stock market indices affects the stabilization performance of optimal monetary policy rules when there is uncertainty about the structure of the economy. With a simulation model of the U.S. economy we show that the...

We estimate monetary policy reaction functions with threshold effects for the Deutsche Bundesbank using a real-time data set. Estimates based on the deviation of inflation from the Bundesbank's inflation target as threshold variable suggest a switch to a stronger output gap response in the...

This paper studies whether the observed high correlation between monetary policy in the U.S. and the Euro area can be explained by economic fundamentals, i.e. by macroeconomic interdependence between the two regions. We show that an optimal monetary policy reaction function for the ECB that...

This paper studies regime dependence in the effects of monetary policy shocks for the U.S. using a threshold vector autoregressive model. In a high inflation regime the standard results from the literature obtain. In a low inflation regime output shows no significant response to monetary policy...

This paper uses real-time data for the U.S. to estimate out-of-sample forecast uncertainty about the Federal Funds Rate. By combining a Taylor rule with an unobserved components model of economic fundamentals I separate forecast uncertainty into economically interpretable components that...
