Price leadership in a homogeneous product market

The present paper reexamines the price-setting Stackelberg duopoly with asymmetric and strictly convex cost functions in a homogeneous product market. It demonstrates that in a generic environment, the higher-cost firm is likely to be the price leader. That is, leadership by such a firm is either (a) a unique equilibrium or (b) a payoff- and risk-dominant equilibrium in the observable delay game. Thus, while this paper complements and generalizes the findings of recent studies that indicate the possibility of the higher-cost firm’s leadership in homogeneous product markets, it also contrasts with the traditional literature that predicts the dominant-firm price leadership in various environments.
