Diversity and Quantity Choice in a Horizontally Differentiated Duopoly

Abstract

The Hotelling model is extended where not only can consumers choose to buy from both sellers (multi-brand purchase), buying multiple units from one seller is also considered (within-brand multi-unit purchase). When an increase of the demand for within-brand multi-purchase exceeds a threshold: (i) firms’ strategies are switched from single-brand equilibrium with higher prices to multi-brand equilibrium with lower prices, if the incremental value from consuming an additional unit of the same product is independent of the preference for diversity; (ii) the direction of such equilibrium-switch is reversed if the two types of multi-purchase are substitutes.
