Abstract: Abstract Spatial interaction modelling defines a theory of movement rather than a theory of location (Davies 1976). It has no rigid underlying assumptions such as in central place theory and was originally formulated around a series of mathematical models, based on the gravity concept analogous to Newton’s law in physics. This gravity model has been applied to many different problems in spatial interaction modelling (for example, traffic movements, population flows and shopping trips). It is in the study of a shopping trip that is of interest here, particularly the form of the gravity model derived under the time discounting of shopping opportunities as a differential equation (termed the ‘supermarket’ equation in Baker 2000
