Forrester 1995 FellowArchived at the Wayback Machine This model is presented more fully in Forrester's 1971 World Dynamics, and is notable primarily because it served as the initial basis for the World3 model used by Donella Meadows and Dennis Meadows in their popular 1972 book The Limits to Growth. The paper also gives an overview of Forrester's model of world dynamics that correlates population, food production, industrial development, pollution, availability of natural resources, and quality of life, as well as projections of those values into the future under various assumptions. The paper further suggests that measures to reduce the shortage - such as the conversion of land use from housing to industry, or an increase in real estate taxes to spur redevelopment of property - would counter-intuitively create the result desired when enacting the failed policies. an increase in the amount of low-income housing available, or a reduction in real estate taxes) counter-intuitively serve to make the situation worse by increasing the population but not the availability of jobs, so that the relative shortage increases. The paper summarizes the results of a previous study on the system dynamics governing economic dynamics in urban centers, which showed 'how industry, housing, and people interact with each other as a city grows and decays.' The study's findings, presented more fully in Forrester's 1969 book Urban Dynamics, suggest that the root cause of depressed economic conditions is a significant shortage of job opportunities relative to the population level, and that the most popular solutions proposed at the time (e.g. ![]()
