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...

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...

The move to monetary union in Europe led to convergence of interest rates among the participating countries. This was associated with notable cross-country differences in the behaviour of key macroeconomic aggregates. Compared to the low interest rate countries, former high interest rate...

This paper quantifies the economic influence that shocks to EMU cohesion, which in turn reflect the incomplete nature of the monetary union, have on the rest of the world. Disentangling euro area stress shocks and global risk aversion shocks based on a combination of sign, magnitude and...

Economic and Monetary Union (EMU) has transformed Europe and has created an integrated pan-European economy. Much research has focused on understanding this integration process and what benefits and costs it entails. This paper identifies a political economy channel of EMU as the monetary union...

The paper presents a model-based assessment of fiscal multipliers operating in the euro area during the period 2011-2014. The assessment is conditional on two distinct reactions of the sovereign risk premium (either responding endogenously to fiscal shocks or being an exogenous process) and two...

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 studies stabilisation policies in a multi-country currency union of small open economies. It abstracts from key factors favouring currency union formation, such as reduced transaction costs and enhanced credibility, which are exogenous to the factors studied here. Demand-side shocks...
