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 demonstrates how a target for money growth can be beneficial for an inflation targeting central bank acting under discretion. Because the growth rate of money is closely related to the change in the interest rate and he growth of real output, delegating a money growth target to the...

In theory, prices of current-month federal funds futures contracts should reflect market expectations of near-term movements in the Federal Reserve's target level for the federal funds rate. However, empirical results show that such measures of market expectations are too noisy to predict...

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,...

I revisit the potential costs and benefits for Sweden of joining the Economic and Monetary Union (EMU) of the European Union. I first show that the Swedish business cycle since the mid-1990s has been closely correlated with the Euro area economies, suggesting that common shocks have been an...

We study the effects of model uncertainty in a simple New Keynesian model using robustcontrol techniques. Due to the simple model structure, we are able to find closed-formsolutions for the robust control problem, analyzing both instrument rules and targetingrules under different timing...

We use a standard quantitative business cycle model with nominal price and wage rigidities to estimate two measures of economic ineffciency in recent U.S. data: the output gap - the gap between the actual and effcient levels of output - and the labor wedge - the wedge between households'...
