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...

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...

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...

Central banks typically have a long-run inflation target that is modestly positive. However, the standard New Keynesian framework prescribes that zero inflation is the optimal long-run target. In this paper, we show that when the baseline New Keynesian model is extended to allow for...

Many empirical studies find robust evidence that marginal cost of production directly depends on the nominal rate of interest. This relationship induces a cost channel for monetary policy transmission. Although the empirical literature provides ample evidence for a cost channel, studies that...

This paper examines the implications of uncertainty about the effects of monetary policy for optimal monetary policy with an application to the current situation. Using a stylized macroeconomic model, I derive optimal policies under uncertainty for both conventional and unconventional monetary...

This paper proposes a channel through which increased openness to international trade can increase a country’s long-run incentive to create inflation. The theoretical justification for this channel is the well known “beggar thy neighbor” incentive, and its dominance relies on a monetary...
