Optimal product variety in a Hotelling model

Author

Listed:
  • Meagher, Kieron J.

Abstract

Consider the Hotelling linear spatial duopoly with firm uncertainty over the consumer mean. As uncertainty about the mean grows relative to the dispersion of consumers, competitive locations become socially optimal. A limit result for discontinuous, log-concave densities is also established.
