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...

The aging of the population shakes the confidence in the economic viability of pay-as-you-go social security systems. We demonstrate how in a political-economy framework the shaken cofidence leads to the downsizing of the social security-system, and to the emergence of supplemental individual...

Following the rationale for regional redistribution programs described in the official documents of the European Union, this paper studies a very simple multi-country model built around two regions: a core and a periphery. Technological spill-overs link firms' productivity in each of the two...

Motivated by the need for more flexible decision-making mechanisms in the European Union, the paper proposes a simple but novel voting scheme for binary decisions taken by committees that meet regularly over time. At each meeting, committee members are allowed to store their vote for future use;...

In most European countries, the prevailing terms of employment, including the nominal wage, can only be changed by mutual consent. I show that this feature implies that workers have a strategic advantage in the wage negotiations when they try to prevent a cut in nominal wages. If inflation is so...

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...

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...

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....

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...
