In a simple dynamic macroeconomic model, it is shown that uncertainty about structural parameters does not necessarily lead to more cautious monetary policy, refining the accepted wisdom concerning the effects of parameter uncertainty on optimal policy. In particular, when there is uncertainty...

The paper analyses the performance of simple interest rate rules which feature a response to noisy observations of inflation, output and money growth. The analysis is based on a small empirical model of the hybrid New Keynesian type which has been estimated on euro area data by Stracca (2007)....

This paper studies the transmission of shocks and the trade-offs between stabilizing CPI inflation and alternative measures of the output gap in Ramses, the Riksbank's empirical dynamic stochastic general equilibrium (DSGE) model of a small open economy. The main results are, first, that the...

Economic outcomes in dynamic economies with forward-looking agents depend crucially on whether or not the central bank can precommit, even in the absence of the traditional inflation bias. This paper quantifies the welfare differential between precommitment and discretionary policy in both a...

Simple models of monetary policy often imply optimal policy behavior that is considerably more aggressive than what is commonly observed. This paper argues that such counterfactual implications are due to model restrictions and a failure to account for multiplicative parameter uncertainty,...

The analysis of this paper demonstrates that when the Phillips curve has forward-looking components, a goal for average inflation - i.e. targeting a j-period average of one-period inflation rates - will cause inflation expectations to change in a way that improves the short-run trade-off faced...

Recent research have provided evidence that backward-looking models fit the data well while purely forward-looking models seem to be inconsistent with data. Consequently, many recent papers in the monetary policy rule literature have used hybrid models, which contain both backward- and...

A central bank pursuing the policy of inflation targeting aims to keep inflation as close as possible to a pre-announced value. But which 'inflation' should this be? Quarterly, annual, biennial? In theoretical models it is typically inflation during one period. We analyze how changing the period...

We start from the assertion that a useful monetary policy design should be founded on more realistic assumptions about what policymakers can know at the time when policy decisions have to be made. Since the Taylor rule – if used as an operational device - implies a forward looking behaviour,...
