Abstract
This paper constructs a model of shopping behaviour in which the frequency of shopping is endogenous. It identifies the size of an equilibrium market area for a set of consumers and derives theoretical expressions for the total number of trips to a shopping centre, the average distance travelled, the average number of trips per shopper and the average distance travelled to shop per period. These characteristics are functions of income, population density, travel costs, inventory costs, shopping costs, and the cost of retailing. (Author/publisher).
