Andy Rose (2000), followed by many others, has used the gravity model of bilateral trade on a large data set to estimate the trade effects of monetary unions among small countries. The finding has been large estimates: Trade among members seems to double or triple, that is, to increase by...

We compare risk sharing in response to demand and supply shocks in four types of currency unions: segmented markets; a banking union; a capital market union; and complete financial markets. We show that a banking union is efficient at sharing all domestic demand shocks (deleveraging, fiscal...

We study the macroeconomic effects of internal devaluations undertaken by a periphery of countries belonging to a monetary union. We find that internal devaluations have large and positive output effects in the long run. Through an expectations channel, most of these effects carry over to the...

We ask whether Poland is at risk of the boom-bust problem that has afflicted economies around the time of euro adoption. Our answer, inevitably, is mixed. On the one hand the fact that Poland is an outlier, credit-growth wise, accentuates the danger of a boom if one believes in mean reversion....

During the last few years there has been a renewed analysis in currency unions as a form of monetary arrangement. This new interest has been largely triggered by the Euro experience. Scholars and policy makers have asked about the optimal number of currencies in the world economy. They have...

In this paper we analyze whether common currency' countries that is, dollarized and independent currency union countries have outperformed countries that have a currency of their own. The paper is empirical and estimates jointly the probability of being a common currency country and outcome'...

This paper develops a new instrumental-variable (IV) approach to estimate the effects of different exchange rate regimes on bilateral outcomes. The basic idea is that the characteristics of the exchange rate regime between two countries (exchange rate variability, fixed or float, autonomous or...

Does leaving a currency union reduce international trade? We answer this question using a large annual panel data set covering 217 countries from 1948 through 1997. During this sample a large number of countries left currency unions; they experienced economically and statistically significant...

This paper analyzes reforms and adjustments in the context of the Euro and the global financial crises. Taking the perspective of the evolutionary approach to institutions, the formation of a new currency area is not unidirectional. The process leading to the euro is an example of a common...

This paper applies a full-information technique to test for the presence of contagion across the money markets of ERM member countries. We show that whenever it is possible to estimate a model for interdependence, a test for contagion based on a full information technique is more powerful. We...
