This paper extends the New Keynesian model to allow for stochastic shifts in the monetary policy regime. Agents cannot observe the regime and use a Bayesian learning rule to make optimal inferences. Price setting is adapted to this environment: lagged expectations about monetary policy influence...

This paper analyses the degree of price rigidity and of inflation persistence across different product categories with particular focus on regulated prices and services for the individual EU15 countries, as well as for the EU15 and the euro area aggregates. We show that services and HICP...

This paper uses disaggregated CPI time series to show that a break in the mean of French inflation occurred in the mid-eighties and that the 1983 monetary policy shift mostly accounted for it. CPI average yearly growth declined from nearly 11% before the break date (May 1985) to 2.1% after. No...

This paper compares the Calvo model with a Taylor contracting model in the context of the Smets-Wouters (2003) Dynamic Stochastic General Equilibrium (DSGE) model. In the Taylor price setting model, we introduce firm-specific production factors and discuss how this assumption can help to reduce...

This paper analyses the degree of inflation persistence in the EU15, the euro area and each of its member states using disaggregate price indices from the Harmonised Index of Consumer Prices. Our results reveal substantial heterogeneity across countries and indices. The overall results, based on...

Surprisingly it did not, or at least not directly. Using micro data on consumer prices and sectoral inflation rates from 6 euro area countries, spanning several years before and after the introduction of the euro, we look at whether EMU has altered the behaviour of retail price setting and/or...

This paper studies optimal discretionary policy with parameter uncertainty about inflation inertia. Optimal policy rules and impulse responses are presented within a hybrid New-Keynesian model estimated for the euro area by Smets (2003). We find that it may be optimal for policy to respond more...

We build a stylised 12-country model of the euro area and use it to analyse why differences in national inflation and growth rates arise within the European monetary union. We find that inflation persistence is a key potential explanatory factor. Other more frequently mentioned reasons, like...

How monetary policy should be set optimally when the structure of the economy exhibits inflation persistence is an important question for policy makers. This paper provides an overview of the implications of inflation persistence for the design of monetary policy. JEL Classification: E52, E58

This study investigates the pricing behaviour of firms in the euro area on the basis of surveys conducted by nine Eurosystem national central banks, covering more than 11,000 firms. The results, robust across countries, show that firms operate in monopolistically competitive markets, where...
