Covering a full array of topics in open economy macro and public economics, Fiscal Policies and Growth in the World Economy has been thoroughly revised and extended. The added material in this new edition includes stochastic rational-expectations extensions of the Mundell-Fleming model, the development of a dynamic-optimizing approach of the trade balance, and an entirely new part on issues of international economic convergence, which also contains a comprehensive policy overview. Other chapters have been updated or reorganized, and there is a brief guide to solving typical dynamic macro problems along with a printout of software suitable for numerical simulations. A companion diskette containing solutions in dynamic macro problems and some sample programs is available in GAUSS for IBM. The exercises and solutions manual by Krueger, Ostry, and Yuen has also been updated and extended. Fiscal Policies and Growth in the World Economy has been used successfully in graduate and senior undergraduate courses in international economics and public finance. The objective of this new edition remains the same as before: to treat the major topics in macro and public economics using both traditional and modern approaches. The traditional approach is first explained, from the simple income-expenditure model to the more advanced stochastic Mundell-Fleming model. The modern intertemporal approach is then presented, starting with the simple two-period model and extending it to a full-fledged dynamic model. Other sections review recent developments in the world economy; government spending, budget deficits, and differences across international taxation; and economic growth in the world economy, especially the convergence of income and growth levels across countries.
