Monopolistic Competition and Preference Diversity

  • Raymond Deneckere
  • Michael Rothschild

This paper presents a general model of the demand for differentiated products which has as special cases two popular models used to analyze welfare and competition in monopolistically competitive markets: the model of spatial competition and the symmetric aggregate benefit function approach. The authors model is especially attractive because it starts from economic primitives: a specification of the set of possible individual preference patterns. It shows how specific properties of the distribution of preferences translate into properties of aggregate demand. This allows the authors to understand the relationship between the distribution of preferences and the degree to which the market introduces biases in product selection.
