This paper examines whether reputation concerns can induce the central bank to implement the time-inconsistent optimal monetary policy in a standard New Keynesian model. The forward-looking nature of this model is in this respect interesting on two accounts: first, it worsens the...

This paper designs, for a broad class of rational-expectations dynamic stochastic general-equilibrium models, interest-rate rules which not only ensure the local determinacy of the targeted equilibrium within the neighbourhood of the targeted steady state, but also prevent the economy from...

Several recent papers are devoted to the examination of the central banker's behaviour in an uncertain economic environment. This paper proposes, from a central banker's point of view, a synthesis of the main sources of uncertainty as well as an illustration of their effects within an analytical...

In a broad class of locally linearizable dynamic stochastic rational-expectations models, I consider various alternative observation sets for the policy maker, each of them made of the history of some endogenous variables or exogenous shocks until some current or past date. For each observation...

How can a currency union be sustained when member states have an exit option? This paper derives how fiscal and monetary policies can ensure the survival of a common currency, if countries want to leave the union. A union-wide central bank can prevent a break-up by setting interest rates in...

We use high-frequency intraday interest rate data to measure euro area monetary policy shocks on the days of ECB interest rate announcements between 2002 and 2013. In line with Gürkaynak et al. (2005), we look at monetary policy shocks along two time dimensions: one related to the current level...

Euro area countries as a whole have experienced a marked downward trend over the 1980s. Over this period, the unemployment rate has increased and economic activity has been sluggish. Changes in the implicit inflation target, viewed as low frequency movements of inflation, might possibly explain...

The present paper investigates the dynamic effects of disinflation shocks for a number of real macroeconomic variables in the euro area. Using structural VARs, we identify disinflation shocks as the only shocks that can exert a long-run effect on inflation as well as other nominal variables...

Central banks are often reluctant to take immediate or forceful actions in the face of new information on the economic outlook. To rationalize this cautious approach, Brainard’s attenuation principle is often invoked: when a policy-maker is unsure of the effects of his policies, he should...

This paper investigates the ability of monetary policy rules to coordinate private agents' expectations when the enforcement of rules is limited. We show that limited enforcement precludes diverging inflation paths ensuring that nominal variables remain bounded in equilibrium. When applied to...
