Price dispersion in a directed search model

Abstract

This paper investigates a directed search model in which some buyers are uninformed about prices. We find that sellers' strategies are given by discrete distributions in any symmetric pricing equilibrium. When the proportion of uninformed buyers is sufficiently high, the unique symmetric pricing equilibrium involves a countably infinite number of atoms. Dispersion de prix dans un modèle de recherche dirigée. Ce papier étudie un modèle de recherche dirigée dans lequel certains acheteurs sont mal informés sur les prix. Nous trouvons que les stratégies des vendeurs sont données par les distributions discrètes dans tout equilibre de prix symmétrique. Quand la proportion des acheteurs qui ne connaissent pas les prix est suffisament élevée, le seul equilibre de prix symmétrique concerne un nombre dénombrable infini des atomes.
