The model of oligopoly between <I>N </I>retail stores, treated in the second paper of this series, is extended to consider competition between groups or 'chains' within which the location and sizes of stores are coordinated to promote organizational objectives. This model of oligopolistic competition...</i>

In three related papers the economic and spatial characteristics of a set of retail stores locating under welfare-maximizing and profit-maximizing criteria are explored. In this first paper, a set of location-spatial interaction models is formulated and the locations and sizes of stores which...

This paper examines a variety of issues within the context of two main themes: the formation of travel demand and economic evaluation measures which are mutually consistent within a theory of rational choice; and a consideration of the structure of models which are representations of the trip...

Building on the tabular analyses exemplified in our first paper and widely used in the medical literature, we use generalised linear models to provide a formal, statistical approach to the analysis of mortality and deprivation relationships, and their change over time. Three types of fixed...

In this paper a new approach is developed to the analysis of stratified housing and employment systems which exhibit interdependencies between movers in the allocation process. Vacancy chain models, derived within a mathematical programming framework, are presented and their properties are...

In this paper we examine the relationship between premature mortality and material deprivation both over time (the intercensal period, 1981 - 91) and over space (for the population in wards and ward groups in Wales). Our focus is on the methods of analysis for small area (ward-based) multiple...

In this paper some of the conceptual and empirical issues in the specification and aggregation of deprivation measures used as a basis for resource allocation in the primary health sector are explored. The problems of deriving deprivation payments to general practitioners (GPs) from data...

This paper presents a summary of findings on the design and evaluation of an urban park-and-ride system. Three main aspects are presented: the construction of mixed-mode demand models; the calculation of user benefits; and the consideration of optimization procedures for the design process. The...

In this paper, postcoded data are used to develop spatial interaction models for the registration of individuals with different health centres. With use of a cell-based representation of urban space, indices of accessibility to and market areas for such services are devised. The empirical work...
