This paper seeks to integrate more closely the theory of optimum currency areas with the theory of international trade. The currency area is considered as a continuous variable ranging from zero to one: zero if there is no enlargement, and some positive value otherwise, corresponding exactly to...

The European Monetary System (EMS) has proven to work remarkably well thus far, despite three major realignments. We make an attempt to explain the dynamic stability of the system. This attempt gives a central place to movements in desired transactions balances, or `leads and lags', as they are...

In contrast to conventional analyses of monetary union between two particular countries or sets of countries, this paper treats the possible expansion of a given currency area as a continuous variable ranging from zero to one; zero if there is no expansion and one if all sources of imports and...

This Paper reports on four basic results of tests of the standard gravity equation. First, geography can serve to reflect comparative advantage as well as transportation costs. Second, the effect of distance on bilateral trade is mostly a substitution effect between closer and more distant trade...

How much risk sharing takes place between regions within countries, between countries internationally, and what are the lessons for EMU? We study these questions based on regional data from the US, Canada, the UK and Italy, and national data from an international sample of 23 OECD countries,...

What purpose does the European Monetary System serve? Who benefits from it? Is it a Deutschmark zone? Or could one argue that, despite the asymmetrical positions of France and Germany, the System does serve a certain collective interest? An attempt to answer these questions reveals a basic...

We argue that wages have increased so far ahead of labour productivity in East Germany as to produce a problem that will continue to hound German policy-makers for the next two decades. Despite rapid rates of capital accumulation (around 9%) and growth (around 5%) in East Germany over the coming...

The discussion of monetary policy in France, which is intended for a chapter in a general handbook on monetary policy that will cover a number of other countries as well, begins with the early postwar period and carries the story up to the present. A separate section analyses the new framework...

In this paper we test the well-known hypothesis of Obstfeld and Rogoff (2000) that trade costs are the key to explaining the so-called Feldstein-Horioka puzzle. Our approach has a number of novel features. First, we focus on the interrelationship between trade costs, the trade account and the...
