ABSTRACT
Consider, as a starting point, the performance indicators for marketed goods and services outlined by Clarke and Wilson in Chapter 5. Broadly, the suggested indicators are as follows:
Catchment population of a centre Service availability Benefit, or consumer surplus Total revenue attracted Residential travel costs Service availability per head Benefit per head
There are two points to be made about this framework. The first is that all the indicators are based around an interaction variable of the form
where i and j are locations, g is the type of good or service and m is a persontY Pe.
