Endogenous duopolies

Abstract: This paper investigates an oligopolistic market with vertical product differentiation, where both qualities and consumers are represented by unidimensional intervals. We examine the Nash equilibrium with positive profits per each firm in the oligopoly game with different production costs. We show that under standard conditions on consumers’ preferences an endogenous duopoly will arise.
