We model an international union as a group of countries deciding together the provision of certain public goods and policies because of spillovers. The countries are heterogeneous either in preferences and/or in economic fundamentals. The trade off between the benefits of coordination and the...

Financial integration generates macroeconomic spillovers that may require international monetary policy coordination. We show that individual central banks may set nominal interest rates too low or too high relative to the cooperative outcome. We identify three sufficient statistics that...

Why should multilateral lending exist in a world where private capital markets are well developed and governments have their own bilateral aid programs? If lending by the World Bank, IMF, and regional development banks has an independent rationale, it must rest on advantages generated by the...

We examine the extent to which developing countries that do little, if any research and development themselves benefit from R&D that is performed in the industrial countries. By trading with an industrial country that has large 'stocks of knowledge' from its cumulative R&D activities, a...

This paper reviews the management of the debt crisis to date, and considers several possible alternative approaches for international cooperation in the future. The first part of the paper briefly reviews the scope of the crisis, and some of the reasons for its onset. Then, the paper describe...

The paper presents a model of a monetary union designed to illuminate monetary and exchange rate policy in the West African Monetary Union (UMOA). Emphasis is placed on the interaction of the members of UMOA with each other, through the common central bank, and on their interaction with France...

Using two decades of data from twelve low-income countries in West Africa, we show that dust carried by harmattan trade winds increases infant and child mortality. Health investments respond to dust exposure, consistent with compensating behaviors. Despite these efforts, surviving children still...

Liberalization of tropical agricultural markets has brought globalization, in the sense that all producers now face world rather than domestic prices. Producer prices have tended to rise as a share of fob prices as intermediation costs and tax has declined. However, in conjunction with inelastic...
