We investigate the implications of cross-country heterogeneity within the euro area for the design of optimal monetary policy. We build an optimizing-based multi-country model (MCM) describing the euro area in which differences between structural parameters across countries are allowed. Using...

This note estimates several constrained versions of an optimization-based multi-country model to test the sources of heterogeneity within the euro area. We show that the main source is the asymmetry of shocks affecting the economies and that the heterogeneity of behaviors does not seem to be of...

In this paper, we investigate the sources of heterogeneity within the euro area. For this purpose, we build an optimization-based multi-country model (MCM) that allows different sources of heterogeneity across countries, both in terms of behavior of economic agents and in terms of asymmetry of...

Using two estimated models for the euro area and the United States, this paper investigates whether the observed difference in the amplitude of the interest rate cycle since 1999 in both areas is due to differences in the estimated monetary policy reaction function, differences in the structure...

This note applies H∞ methods to an estimated hybrid monetary policy model and derives standard and robust optimal interest rate rules. We find that the 'robust' central banker responds more aggressively than it does without concerns for robustness and that the responses of the state variables...

This paper studies the implications of parameter estimation uncertainty on the central banker behaviour. It first describes the optimal monetary policy rule obtained by the linear quadratic stochastic control approach. The treatment of parameter estimation uncertainty is covered by the...

The euro area as a whole has experienced a marked downward trend in inflation over the past decades and, concomitantly, a protracted period of depressed activity. Can permanent and gradual shifts in monetary policy be held responsible for these dynamics? To answer this question, we embed...

This article addresses the existence of a wide range of estimated government spending multipliers in a dynamic stochastic general equilibrium model of the euro area. Our estimation results and counterfactual exercises provide evidence that omitting the interactions of key ingredients at the...
