Vertical Product Differentiation, Entry-Deterrence Strategies, and Entry Qualities
We analyze the potential entry of a new product into a vertically differentiated market. Here the entry-deterrence strategies of the incumbent firm rely on ï¾“limit qualities.ï¾” The model assumes quality-dependent marginal production costs and considers sequential quality choices by an incumbent and an entrant. Entry-quality decisions and the entry-deterrence strategies are related to the fixed cost necessary for entry and to the degree of consumersï¾’ taste for quality. We detail the conditions under which the incumbent increases its quality level to deter entry. Quality-dependent marginal production costs in the model entail the possibility of inferior-quality entry as well. Welfare is not necessarily improved when entry is encouraged rather than deterred.
