N2  - This book examines projections for the United States economy over longer periods (of between five and ten years), and within this time scale the framework is annual rather than quarterly. The book which used the Wharton annual industry forecasting model combined the national accounts approach of most short term models with a 50 sector input-output table. In all, there are 155 stochastic equations, 191 definitional identities, 346 endogenous and 90 exogenous variables
