The simple circular model of horizontal product differentiation, in which firms compete in price, is characterized by excessive firm entry in equilibrium. When non-monotonic network effects are present, this result no longer holds. If consumers differ in their optimal number of other consumers choosing their same good, entry in equilibrium can be insufficient.
