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...

The cross-country regression relating the relative price level to the relative GDP level is significant and stable. But there is no shorter-term trade-off between fast real convergence and low inflation. Such a tradeoff characterises the dynamic process moving the economy along the regression...

We study lessons from the experience of Finland in meeting the challenges of joining the euro area at its outset and its subsequent economic success. Traditional optimum currency area theory is too limited a framework for judging the experience in qualifying and membership.Five main factors have...

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 is intended to theoretically present divergent business cycles as effects of a monetary union, even in the absence of asymmetric, exogenous shocks. The main inference form the model developed in this paper says that microeconomic optimization may lead to sub-optimal macro states and...
