Persistent price differences across euro area countries are an indication of incomplete economic integration. We analyze long and short run developments of price level dispersion in the euro area and compare the results with the situation in the US. We find that monetary and economic integration...

Under monetary union, economic dynamics may diverge across countries due to regional inflation differentials and a pro-cyclical real interest rate channel, yet stability is generally ensured through endogenous adjustment of the real exchange rate. The speed of adjustment depends, inter alia, on...

Recent studies find that short-term fluctuations in EMU have been symmetric. This finding leads to benign views on the functioning of EMU as an optimum currency area (OCA), that are difficult to reconcile with the sovereign debt crisis. We try to solve this puzzle by looking at medium-term...

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, by disentangling euro area stress shocks and global risk aversion shocks on the basis of a combination of sign, magnitude...

I rely on a historical natural experiment to provide, for the first time, a causal estimate of the effect of currency unions on international trade. Since the seminal paper by Rose (2000), a large literature has developed around currencies as a trade cost. However, self-selection and endogeneity...

Monetary union can benefit countries suffering from policy credibility problems if it eliminates the inflation bias and also allows for more efficient management of certain shocks. But it also carries costs as some stabilization may be feasible even in the absence of credibility, and this may be...
