Haraguchi, Junichi; Hirose, Kosuke study Endogenous Timing in a Price-Setting Mixed Oligopoly.
ABSTRACT: We investigate the endogenous order of moves in a price-setting mixed oligopoly model, comprising two private firms and a public firm. We show that sequential moves emerge as the equilibrium in the observable delay game. Specifically, one of the private firms and the public firm set their prices in period 1, and the other private firm does so in period 2, in equilibrium, if their goods are not significantly differentiated. This is a clear contrast to a mixed duopoly where a simultaneous move game is a unique equilibrium. We also discuss a number of extensions and the robustness of our result.
