A Look at Urban Dynamics: The Forrester Model and Public Policy

A review of Urban Dynamics [1] and additional simulation by the authors is presented. Structural choices of boundary conditions, major subsectors, and multiplier relationships in the Forrester model are examined. Some of their implications and shortcomings are noted. Forrester's policy conclusions and implicit evaluation criteria are discussed and related to our alternative assumptions and simulation.
