We apply ideas from fiscal federalism to reassess how fiscal authority should be delegated within a monetary union. In a real-economy model with no fiscal externalities, in which local fiscal authorities have an informational advantage about the preferences of their citizens for public spending...

The Maastricht Treaty on Europe Union features an Excessive Deficit Procedure limiting the freedom to borrow of governments participating in the European monetary union. One justification is to prevent states from over- borrowing and demanding a bailout which could divert the European Central...

We study cross-country risk sharing as a second-best problem for members of a currency union using an open economy model with nominal rigidities and provide two key results. First, we show that if financial markets are incomplete, the value of gaining access to any given level of aggregate risk...

Formation of the Euro area raises new questions about the coordination of monetary and fiscal policy. Using a New Neoclassical Synthesis (NNS) model, we show that a common monetary policy, responding to area-wide aggregates, has asymmetric effects on countries within the union, depending on...

Europe's monetary union is part of a broader process of integration that started in the aftermath of World War II. In this "political guide for economists" we look at the creation of the euro within the bigger picture of European integration. How and why were European institutions established?...

This paper studies fiscal spillovers in a monetary union. The focus of the analysis is on the interaction between the fiscal policy of member countries (regions) and the central monetary authority. When capital markets are integrated, the fiscal policy of one country will influence equilibrium...

some stylized facts relating the regional dispersion in headline inflation rates in the euro area as well as in the main components of the consumer price index. We find that a relatively large proportion of it occurs in the Service category of the EU's harmonized consumer price index (HICP). We...

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...

We lay out a tractable model for fiscal and monetary policy analysis in a currency union, and analyze its implications for the optimal design of such policies. Monetary policy is conducted by a common central bank, which sets the interest rate for the union as a whole. Fiscal policy is...

This paper explores the gains to monetary union. We consider a two-country overlapping generations model. Agents work when young and have random tastes over the composition (domestic vs. foreign goods) of old age consumption. In equilibrium, governments require that local currency be used for...
