Borrowing from the experience of environmental markets, this paper proposes a system of tradable deficit permits as an efficient mechanism for implementing fiscal constraints in the European Monetary Union: having chosen an aggregate target for the Union and an initial distribution of permits,...

In our European Economic Review (2002) paper, we used pre-1998 data on countries participating in and leaving currency unions to estimate the effect of currency unions on trade using (then-) conventional gravity models. In this paper, we use a variety of empirical gravity models to estimate the...

This paper explores the implications of the European single currency within a simple sticky price intertemporal model. The main issue we focus on is how the euro may alter the responsiveness of consumer prices to exchange rate changes. Our central conjectures is that the acceptance of the euro...

Larger data sets, with more countries and a longer span of time, exhibit systematically larger effects of European monetary union on trade. I establish this stylized fact with meta-analysis and confirm it by estimating a plain-vanilla gravity model. I then explain this finding by examining...

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...

What makes an asset a “safe asset”? We study a model where two countries each issue sovereign bonds to satisfy investors' safe asset demands. The countries differ in the float of their bonds and their resources/fundamentals available to rollover debts. A sovereign's debt is more likely to be...

We study the effects of labor mobility within a currency union suffering from nominal rigidities. When the demand shortfall in depressed region is mostly internal, migration may not help regional macroeconomic adjustment. When external demand is also at the root of the problem, migration out of...

What are the macroeconomic effects of tax adjustments in response to large public debt shocks in highly integrated economies? The answer from standard closed-economy models is deceptive, because they underestimate the elasticity of capital tax revenues and ignore cross-country spillovers of tax...

In this paper I focus on two specific hazard areas in the transition from Stage Two to Stage Three of European economic and monetary union (EMU), as well as on some key problems of Stage Three that EMU's monetary and fiscal structures appear ill-prepared to handle. The transitional hazards are...

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...
