Regional Stabilization: A Model for Policy Decision

A policy simulative model with the main purpose of simulating the effects of alternative policy moves and obtaining an accurate read-out of resulting urban-suburban conditions is the focus of this paper. The model deals with the movement of various population groups and the resulting effects on some very broad indicators of city-suburban life, rather than with particular topics like transportation, land use and the like. The level of abstraction is thus intermediate and is directed at providing practical policy suggestions for a particular city-Newark-for which the model is calibrated. The model, however, is general enough in nature so that it can be applied to other urban-suburban complexes and therefore the policy suggestions made on a fairly broad basis. The outputs of the model are graphically represented to show the results of alternative policies which then may be compared. As a side benefit the inputs to the model can also serve as a "social report" on the present status of an area. Policy questions to be answered by the model include: Should a city budget be directed somewhat differently? Should a city ask the state or federal government for funding and for how much? What may be expected from imposing a city sales tax, weighing the revenue benefit against costs of lost sales or citizens? And last, would the federal government not be better off by simply giving money to the poor directly instead of to cities?
