A Four-Sector World Model: Approach and Results

Major criticism of the MIT world models (Forrester’s World II and Meadows’ World III /1, 2/) has been directed to the fact that the world system was aggregated into a single undifferentiated structure. The results of necessity represented averages bearing little relationship to the actual world of nations at vastly different levels of development. I attempted to overcome this deficiency through the development of a 4-sector world model, where each sector contained Forrester’s world model II model structure with the proper sector-specific parameters.
