ABSTRACT

Obviously the detailed form of the model turns on the 'location functions' F., F~., F~. and F~ .• In the rest of the1 lJ lJ lJ paper, Allen et aZ. discuss the form of F~. in detail but notlJ the others. Indeed, in the model whose results are reported, the focus is entirely on residential patterns and the economic sector is treated in aggregate with a single variable X. being

1 used to represent jobs at i. It would in fact be more consistent, in the light of Equation (6.27) to use Dj for this, and this is what is done below. It is also not clear from the text how many zones are allowed to have jobs: that is, the extent to which they are concentrated in the centre of the study area. Here, the formulation as presented is modified to allow for all zones having jobs. The attractiveness function can then be taken as

which obviously needs some explanation.
