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...

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...

The fiscal consolidation measures adopted in many euro area countries over 2010-13 reduced excessive domestic fiscal imbalances, but came at the cost of short-term output losses. This simultaneous tightening of fiscal policy raised concerns that such output losses might be exacerbated by...

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...

This paper studies export adjustment to negative shocks in currency unions. I consider the hitherto ignored role of trade costs and taxes in internal devaluations, which have been brought to the fore of international policy during the recent euro periphery crisis. Trade costs can limit the...

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 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...
