We propose a new and time-varying optimum currency area (OCA) index for the euro area in assessing the evolution of the OCA properties of the monetary union from an international business cycle perspective. It is derived from the relative importance of symmetric vs. asymmetric shocks that result...

In this paper we provide a positive exercise on past business-cycle correlations and risk sharing in the European Union, and on the ability of insurance mechanisms and fiscal policies to smooth income fluctuations. The results suggest in particular that while some of the new Member States have...

This paper addresses the effects of the European Economic and Monetary Union (EMU) since the introduction of the euro -- on economic and financial structures, institutions and performance. What type of changes is the euro fostering? What forces is it setting in motion that were not there before?...

This paper presents evidence for structural differences in economic growth dynamics between the current EU and the central- and eastern European accession countries. Two important results emerge from the analysis. First, accession countries have posted higher average growth and wider output...

Two seemingly unconnected empirical results suggest an intriguing mechanism. First, economic integration helps harmonize prices internationally, with trade being the primary channel (Rogoff 1996, Goldberg and Knetter 1997). Second, monetary union may greatly increase the amount of trade among...

We study cross-country price differences in the European market for new passenger cars based on detailed pricing and technical data. Car prices in Europe converged until the year 2003, but not thereafter. Within the EU 15 countries the price range of the median model in 2004 was close to 20...

This paper analyzes the implications of price-setting and incomplete financial markets for optimal monetary cooperation. The main objective is to provide the basic intuitions concerning the role of the main international frictions on optimal policy within a simple Dynamic Stochastic General...

This paper discusses the choice of an optimal external anchor for oil exporting economies, using optimum currency area criteria and simulations of a simple model of a small open economy pegging to a basket of two currencies. Oil exporting countries .in particular those of the Gulf Cooperation...

This paper brings together several strands of the literature on the endogenous effects of monetary integration: i.e., whether sharing a single currency may set in motion forces bringing countries closer together. The start of EMU has spurred a new interest in this debate. Four areas are...
