Minimum-cost distances in spatial analysis

An axiomatic approach to distance is developed which focuses on thosebehavioral concepts of distance related to movement in space. In particular,spatial movement by behaving units is postulated to involve a choice fromamong some set of abstract trips in space, and implicitly, to involve theminimization of some relevant notion of trip costs. In this context, therelevant behavioral notion of distance in space is taken to be theminimum-cost distance generated by this choice process. These trip-costconcepts extend the classical notions of paths, path lengths, and shortestpaths in metric spaces. Hence many of the analytical results of the paperinvolve extensions of classical shortest-path distance properties tominimum-cost distances. In addition to these extensions, a characterizationtheorem is given which specifies the possible functional relationships between trip costs and their associated path lengths. These relationships include most functional forms which are commonly employed in the literature

[Agglomération et bien-être : le modèle centre-phériphérie à la lumière de Bentham, Kaldor et Rawls]

Différentes approches de l'économie du bien-être sont appliquées au model canonique d'économie géographique développé par Krugman. Plus précisément, les auteurs comparent les deux solutions de marché issues du modèle, l'agglomération et la dispersion, à l'aide du critère de Paréto et de critères de compensation initiés par Kaldor. Ils ont également recours à des fonctions de bien-être social avec aversion pour l'inégalité permettant notamment de considérer les critères utilitaristes et celui de Rawls. Il n'existe pas de réponse nette puisqu'il existe, à partir des critères de compensation, une indétermination quant à la désirabilité de l'agglomération par rapport à la dispersion, et vice-versa. Le choix de la configuration spatiale la plus socialement souhaitable dépend du degré d'aversion pour les inégalités individuelles. Les auteurs mettent également en évidence que le critère utilitariste biaise en faveur de l'agglomération
