This book presents articles that focus on the inter-related issues of choice of exchange rate and monetary policy regimes, and others that use a global macroeconomic model developed by the author and collaborators to quantify the effects of the ‘baby boom’ on global imbalances, costs of disinflation, and the effects of German unification. The book presents new analysis of the euro-zone experience and its applicability to other monetary unions, as well as a discussion of the prerequisites for successful inflation targeting. It is grounded in real-world data, readily accessible to non-specialists, and addresses important economic policy issues.
