In this paper, we examine the performance and robustness of optimised interest-rate rules in four models of the euro area which differ considerably in terms of size, degree of aggregation, relevance of forward-looking behavioural elements and adherence to micro-foundations. Our findings are...

Assigning a discretionary central bank a mandate to stabilize an average inflation rate—rather than a period-by-period inflation rate—increases welfare in a New Keynesian model with an occasionally binding lower bound on nominal interest rates. Under rational expectations, the...

This paper studies optimal discretionary monetary policy in the presence of uncertainty about the degree of financial frictions. Changes in the degree of financial frictions are modelled as changes in parameters of a hybrid New-Keynesian model calibrated for the UK, following Bean, Larsen and...

The zero lower bound (ZLB) constraint on interest rates makes speed limit policies (SLPs)—policies aimed at stabilizing output growth—less effective. Away from the ZLB, the history dependence induced by a concern for output growth stabilization improves the inflation-output tradeoff for a...

We study alternative monetary policy strategies in the presence of the lower bound on nominal interest rates and a low equilibrium real rate using an estimated DSGE model for the euro area. We find that simple feedback rules that implement inflation targeting result in a binding lower bound...

We study optimal monetary policy in a flexible state-dependent pricing framework, in which monopolistic competition and stochastic menu costs are the only distortions. We show analytically that it is optimal to commit to zero inflation in the long run. Moreover, our numerical simulations...

In an economy with an occasionally binding zero lower bound (ZLB) constraint, the anticipation of future ZLB episodes creates a trade-off for discretionary central banks between inflation and output stabilization. As a consequence, inflation systematically falls below target even when the policy...

We study optimal monetary and fiscal policy in a New Keynesian model where occasional declines in agents' confidence can give rise to persistent liquidity trap episodes. Unlike in the case of fundamental-driven liquidity traps, there is no straightforward recipe for mitigating the welfare costs...

Modifying the objective function of a discretionary central bank to include an interest-rate smoothing objective increases the welfare of an economy where large contractionary shocks occasionally force the central bank to lower the policy rate to its effective lower bound. The central bank with...

How does the need to preserve government debt sustainability affect the optimal monetary and fiscal policy response to a liquidity trap? To provide an answer, we employ a small stochastic New Keynesian model with a zero bound on nominal interest rates and characterize optimal time-consistent...
