What is the optimal number of currencies in the world? Common currencies affect trading costs and, thereby, the amounts of trade, output, and consumption. From the perspective of monetary policy, the adoption of another country's currency trades off the benefits of commitment to price stability...

The main goal of this paper is to estimate to what extent the federal government of the United States insures member states against regional income shocks. We find that a one dollar reduction in a region's per capita personal income triggers a decrease in federal taxes of about 34 cents and an...

The global financial crisis which erupted in the United States instantaneously swept across Europe. Like the United States, the European Monetary Union (EMU) was ripe for a crash. It had its own real estate bubble, specifically in Ireland and Spain, indulged in excessive deficit spending,...

At a time of historic challenges to the viability of the Eurozone, we assess the contribution of the EU and the Euro to equity market integration in Europe. We use a simple and essentially model free measure of bilateral market segmentation: two countries are segmented if there is a wide...

This paper reviews the first evidence on the impact of European Monetary Union on European capital markets, one year after the launch of the single currency. Our assessment of this evidence is very favourable. On almost all counts EMU has either changed the European financial landscape already...

After reviewing the theoretical arguments that may link the adoption of...

A country's suitability for entry into a currency union depends on a number of economic conditions. These include, inter alia, the intensity of trade with other potential members of the currency union, and the extent to which domestic business cycles are correlated with those of the other...

Once upon a time, in the 1990s, it was widely agreed that neither Europe nor the United States was an optimum currency area, although moderating this concern was the finding that it was possible to distinguish a regional core and periphery (Bayoumi and Eichengreen, 1993). Revisiting these...

We take stock of the history of the European Monetary Union and pegged exchange-rate regimes in recent decades. The post-Bretton Woods greater financial integration and under-regulated financial intermediation have increased the cost of sustaining a currency area and other forms of fixed...

Between 2000 and 2012, the Portuguese economy grew less than the United States during the Great Depression and less than Japan during its lost decade. This paper asks why this happened, with a particular focus on the slump between 2000 and 2007. It describes the main facts of Portugal's recent...
