Abstract

. We introduce a flexible third‐degree price discrimination framework by modeling the information firms possess about consumers’ locations (preferences) on the Salop circle as a partition. Higher information quality is translated into a partition refinement. In the limit, we obtain the perfect price discrimination paradigm. We show that the free‐entry equilibrium number of firms exhibits a U‐shape as a function of the quality of information. This implies that imperfect price discrimination generates the most efficient free‐entry outcome. JEL classification: D43, L11, L43 Discrimination imparfaite par les prix, structure de marché et efficacité. Les auteurs produisent un cadre d’analyse flexible de la discrimination par les prix au troisième degré en modélisant l’information que les firmes possèdent à propos de la localisation (préférences) comme base de découpage dans un cercle de Salop. Une plus grande qualité d’information se traduit par un découpage plus fin. A la limite, on obtient le paradigme parfait de discrimination par les prix. On montre que le nombre de firmes en équilibre quand l’entrée est libre est une fonction en forme de U dans son rapport avec la qualité de l’information. Cela implique que la discrimination imparfaite par les prix engendre le résultat le plus efficace quand l’entrée est libre.
