This Paper examines the importance of the distribution of consumers in Hotelling's circle on the comparison between the optimal and the market equilibrium levels of diversity. It finds that when most consumers are located very close to the firms, the result of Salop that the equilibrium number of firms is larger than the optimal one (surplus maximizing) can be reversed.
