This paper shows that monetary policy should be delegated to a central bank that cross-checks optimal policy with information from the Taylor rule. Attaching some weight to deviations of the interest rate from the interest rate prescribed by the Taylor rule is beneficial if the central bank aims...

We highlight how detrending within Structural Vector Autoregressions (SVAR) is directly linked to the shock identification. Consequences of trend misspecification are investigated using a prototypical Real Business Cycle model as the Data Generating Process. Decomposing the different sources of...

We analyse the implications of asymmetric monetary policy rules by estimating Markovswitching DSGE models for the euro area (EA) and the US. The estimations show that until mid-2014 the ECB's response to in ation was more forceful when in ation was above 2% than below 2%. Since then, the ECB's...

This paper analyzes monetary policy in a model with a potential unanchoring of inflation expectations. The degree of unanchoring is given by how sensitively the public's long-run inflation expectations respond to inflation surprises. I find that optimal policy moves the interest rate...

We study the optimal combination of conventional (interest rates) and unconventional (credit easing) monetary policy in a model where agency costs generate a spread between deposit and lending rates. We show that unconventional measures can be a powerful substitute for interest rate policy in...

A key insight from the open economy literature is that domestic price stability is in general not optimal for countries that exert some market power over their terms of trade. Under commitment, a national benevolent monetary policymaker improves upon the allocation associated with stable...

There is growing empirical evidence that the strength of the cost channel of monetary policy differs across countries. Using a New Keynesian model of a two-country monetary union, we show how the introduction of a cost channel (differential) alters the optimal monetary responses to union-wide...

Erceg et al. (2000) show that when both wages and prices are sticky, maximization of expected utility is equivalent to minimizing a loss function with three terms, involving measures of the variability of wage inflation, price inflation and the output gap respectively. Here we generalize their...

We lay out a small open economy version of the Calvo sticky price model, and show how the equilibrium dynamics can be reduced to a tractable canonical system in domestic inflation and the output gap. We employ this framework to analyse the macroeconomic implications of three alternative monetary...

This Paper studies an advantage of commitment over discretion when a central bank observes only noisy measures of current inflation and output, in the context of an optimizing model with nominal-price stickiness. Under a commitment regime, if current policy turns out to be too expansionary...
