A collection of essays in honour of Robert Triffin, the principal architect of the European Payments Union in the 1940s. These works cover topics such as obstacles to international policy co-ordination, the reform of the international monetary system and European monetary integration. The "Open Market" and its ramifications are discussed and the future of the European Monetary System is examined. The text does not concentrate solely on Europe, however, and also examines such subjects as monetary management in Latin America and proposals for co-operative relief of debt in Africa. An overview of the International Monetary System is provided and the future of macroeconomic policy coordination is examined.
