This book, first published in 1973, presents a collection of original contributions to the analysis of international trade and monetary relations by a number of distinguished economists. The papers bear on six topics in trade theory: the inadequacies of classical trade theory, customs unions, immiserising growth, the international transmission of technical change, multinational company behaviour, and comparative trends in income distribution. Chapters dealing with international monetary relations focus on general equilibrium analysis of spot and forward exchange markets, money supply analysis in open economies, devaluation in developing countries, the sharing of the burden of international adjustment, the monetary approach to balance-of-payments theory, and the integration of Keynesian and monetary approaches to international adjustment. Taken together, they summarize much of the most advanced contemporary research in international economics. The volume is unified by the contributors' common belief that economic theory can help solve important and relevant problems in international economic relations. All the contributions represent original work on the frontiers of research in international economics, but they use simple and understandable techniques to reach their conclusions.
