Models of Population Movement and Urban Policy

In the first part of this paper the policy discussions of the Forrester model [1] are compared with those of the urban planners. Contrary to Forrester´s assertions, these are found to be very similar. In the second part of the paper the determinants of population movement are reexamined and found to differ substantially (particularly with respect to policy variables) from both the Forrester model and the implicit model of the urban planners.
