Market Size and Substitutability in Imperfect Competition: A Bertrand-Edgeworth-Chamberlin Model
This paper examines the role of market size in a model of price competition with imperfect substitutes that bridges the Chamberlin and Bertrand-Edgeworth approaches. The author investigates the role of two fundamental parameters in the existence of an equilibrium: the market size, given by the number of competitors, and the degree of substitutability. He proves that (1) for a given number of competitors, a sufficiently large, but finite, degree of substitutability entails nonexistence; and (2) conversely, for a given upper bound on the degree of substitutability, a sufficiently large number of competitors ensures existence. He finally investigates the proximity of an equilibrium (when it exists) to a "competitive outcome," and finds that both high substitutability and large market size are a condition for competitiveness.
