This note analyses product diversity under increasing returns to scale. We employ, in a general equilibrium framework, the model of Perloff and Salop (1985), which synthesizes Hotelling-type and Chamberlin-type models. The main result in the paper provides an instance of the excess diversity of a product, and its interpretation is illustrated diagrammatically.
