This paper elaborates on the alternative measure of persistence recently suggested in Marques (2004), which is based on the idea of mean reversion. A formal distinction between the “unconditional probability of a given process not crossing its mean in period t” and its estimator, is made...

Previous studies have interpreted the rise and fall of U.S. inflation after World War II in terms of the Fed's changing views about the natural rate hypothesis but have left an important question unanswered. Why was the Fed so slow to implement the low-inflation policy recommended by a natural...

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.

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...

An important stylized fact to emerge from the VAR estimates is that exogenous monetary policy shocks (also labelled unsystematic monetary policy) have a delayed, persistent, hump shaped effect on inflation. I argue that this empirical pattern is fragile. In particular it disappears when one...

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 estimates a hybrid New Keynesian model on euro area data and evaluates the performance of different simple policy rules and of the optimal unconstrained rule under commitment. The study reaches two main conclusions. First, inflation is found to be mainly forward-looking in the euro...

The paper shows that US monetary policy has been an important determinant of global equity markets. Analysing 50 equity markets worldwide, we find that returns fall on average around 3.8% in response to a 100 basis point tightening of US monetary policy, ranging from a zero response in some to a...

This paper formalizes the process of updating the nowcast and forecast on output and inflation as new releases of data become available. The marginal contribution of a particular release for the value of the signal and its precision is evaluated by computing "news" on the basis of an evolving...

We propose a theoretical framework for assessing whether a forecast model estimated over one period can provide good forecasts over a subsequent period. We formalize this idea by defining a forecast breakdown as a situation in which the out-of-sample performance of the model, judged by some loss...
