RECERCAT author Martínez Giralt, Xavier author Usategui Diaz de Otalora, J. Mª author Universitat Autònoma de Barcelona. Unitat de Fonaments de l'Anàlisi Econòmica author Institut d'Anàlisi Econòmica 2010 Transport costs in address models of differentiation are usually modeled as separable of the consumption commodity and with a parametric price. However, there are many sectors in an economy where such modeling is not satisfactory either because transportation is supplied under oligopolistic conditions or because there is a difference (loss) between the amount delivered at the point of production and the amount received at the point of consumption. This paper is a first attempt to tackle these issues proposing to study competition in spatial models using an iceberg-like transport cost technology allowing for concave and convex melting functions. open access Aquest document està subjecte a una llicència d'ús Creative Commons.
