With many emerging market currencies tied to the U.S. dollar either implicitly or explicitly, movements in the exchange values of the currencies of major countries have the potential to influence the competitive position of many developing countries. According to some analysts, establishing...

This paper addresses the puzzle of regime-dependent volatility in foreign exchange. We extend the literature in two ways. First, our microstructural model provides a qualitatively new explanation for the puzzle. Second, we test implications of our model using Europe's recent shift to rigidly...

This paper reconsiders the determinants of the exchange rate by studying the historical episode after the fall of the Iron Curtain. Testing a modified portfolio balance model, we attribute the strength of the deutschmark in the early nineties and the puzzling decline of the euro during its...

The theory of international macroeconomics shows that domestic tax policy in a global economy affects foreign economic conditions via complex, dynamic interactions through relative prices, tax revenues, and wealth distribution. This paper proposes a tractable quantitative framework for assessing...

We use a simple graphical approach to represent Social Welfare Functions that satisfy Independence of Irrelevant Alternatives and Anonymity. This approach allows us to provide simple and illustrative proofs of May's Theorem, of variants of classic impossibility results, and of a recent result on...

The thesis of this paper is that more transparent, rule-bound and subtle mechanisms for policy coordination will be needed to ensure the success of an enlarged European Union. A common policy is a public good with distributional implications. Economists have developed a large number of plausible...

This paper develops the thesis that credit market frictions may be an important contributor to high unemployment in Europe. When a change in the technological regime necessitates the creation of new firms, this can happen relatively rapidly in the U.S. where credit markets function efficiently....

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...

A growing body of new research has emphasized the macroeconomic consequences of transactional impediments in factor markets, and their role in the recurrent restructuring requirements of modern economies. We first review the function institutional arrangements play in facilitating transactions...

The creation of the euro and the European Central Bank is a remarkable and unprecedented event in economic and political history: creating a supranational central bank and leaving eleven countries without national currencies of their own. The experience of the first year confirms that one size...
