This volume surveys the state-of-the-art of global international modeling. All 15 models included in the survey feature national or regional disaggregation of the world economy and interdependencies among the various nations and regions. A few are constructed for short-term forecasting, but the primary focus is on long-run models and applications.Macroeconomic, input-output, general equilibrium, trade and exchange rate, and several hybrid models are included. A cross-sectional analysis by the editor compares the structures, linkage mechanisms, methodologies and applications of the various models and concludes with some observations on prospective research trends.
