A two-country model that incorporates many features proposed in the New Open Economy Macroeconomics literature is developed in order to replicate the volatility of the real exchange rate and its disconnect with macroeconomic variables. The model is estimated using data for the euro area and the...

Since the adoption of flexible exchange rates, real exchange rates have been much more volatile than they were under Bretton Woods. However, the volatilities of most other macroeconomic variables have remained approximately unchanged. This poses a puzzle for standard international business cycle...

We assess the global macroeconomic implications of different strategies of official reserve management by developing a large scale new-Keynesian dynamic general equilibrium model of the world economy, calibrated on the euro area, the United States, China, Japan and the rest of the world. An...

The work of Ghironi and Melitz (2005) is at the frontier of international real business cycle (IRBC) models with heterogeneous firms. In their model, the dynamic behaviour of real marginal costs is puzzling: a positive technology shock hitting the home country makes it permanently less...

A Monetary Union is modeled as a technology that makes a surprise policy deviation impossible but requires voluntarily participating countries to follow the same monetary policy. Within a fully dynamic context, we identify conditions under which such arrangement may dominate a coordinated system...

This paper analyzes the macroeconomic consequences of the establishment of a monetary union in the presence of unionized labor markets. It is shown that the effects of the formation of a monetary union depend on several labor market festures, such as the degree of centralization of wage...

We use Italian firm-level data to investigate the impact of trade openness on the distribution of firms across marginal cost levels. In so doing, we implement a procedure that allows us to control not only for the standard transmission bias identified in firm-level TFP regressions but also for...

I analyse the effects of a reduction in the tariffs of a trading partner on the exports of domestic firms. More precisely, I focus on how cross-industry differences in factor intensities and within-industry differences in firm productivities shape the response of the extensive (decision to...

For historical and geographical reasons, the member countries of the European Monetary Union (EMU) display different degrees of external trade openness. The paper lays out a model for a currency area composed of two regions. One region is more open to trade with a third country outside the area...
