Vertical product differentiation and entry deterrence

Abstract

This paper studies how the existence of a potential entrant influences an incumbent’s choice of quality in a model of vertical product differentiation and entry. Both firms face fixed set-up costs and quality-dependent costs of production, and compete on quality and price. With identical quality-dependent costs, the incumbent will always deter entry if possible, i.e. if fixed costs are high. Quality will be set at a level lower than the optimal quality set if entry was accommodated. If entry is not blockaded, quality will be set at a level strictly lower than the optimal quality set under monopoly.
