Abstract

This paper explores the implications of price-dependent demand in spatial models of product differentiation.We introduce consumers with a quasi-linear utility function in the framework of the Salop (1979) model.We show that the so-called excess entry theorem relies critically on the assumption of completely inelastic demand. Our model is able to produce excessive, insufficient, or optimal product variety.A proof for the existence and uniqueness of symmetric equilibrium when price elasticity of demand is increasing in price is also provided.
