In this paper we re-evaluate the empirical evidence on money-inflation Granger causality for the euro area and, in contrast to Trecroci and Vega (2000), conclude that money does in fact Granger cause inflation. We also show that it takes about a year and a half for changes in money growth to...

It is believed that a shock, common to a set of countries with identical fundamentals, has identical outcomes across countries. We show that in general, when specialization in production is such that a common shock creates a missing role for labor mobility across countries, the terms of trade of...

We study environments with sticky prices, wages or portfolios where it is feasible and optimal to use monetary policy to replicate the allocation under full flexibility. In these environments the optimal policy does not depend on the scope of the frictions. In this sense, the strength of the...

This paper compares the monetary transmission mechanism in the US and the 3 largest economies of the euro area. We start by showing that the dynamic responses to a monetary policy shock in each of the four countries are analogous. A model with a small set of frictions that broadly accounts for...

We show that the Friedman rule is optimal in the standard transactions techology monetary model whether the alternative fiscal instrument is a consumption tax, an income tax, or both, and whether taxes are paid with money or not. These results are at odds with recent literature. We show that an...

We derive principles of optimal short run monetary policy in a real business cycles model, with money and with monopolistic firms that set prices one period in advance. The only distortionary policy instruments are the nominal interest rates and the money supplies. In this environment it is...

This paper assesses the relevance of the exchange rate regime for stabilization policy. This regime question cannot be dealt with independently of other institutions, in particular how .fiscal policy is designed. We show that once .fiscal policy is taken into account, the exchange rate regime is...

This paper investigates the dynamics of aggregate wages and prices in the United States (US) and the Euro Area (EA) with a special focus on persistence of real wages, wage and price inflation. The analysis is conducted within a structural vector error-correction model, where the structural...

This paper investigates the persistence of aggregate wages and prices in Portugal assuming a model of a unionized economy with imperfect competition. An impulse response analysis is conducted where the structural shocks are identified by taking into account the long-run properties of the model,...

The aim of this paper is to assess inflation forecasting acurracy over the short-term horizon using Consumer Price Index (CPI) disaggregated data. That is, aggregating forecasts is compared with aggregate forecasting. In particular, three questions are addressed: i) one should bottom-up or not,...
