We revisit and compare equilibrium uniqueness results for homogeneous Cournot oligopolies. In doing this we provide various useful and interesting results for which it is difficult to give appropriate reference in the literature. We also propose problems for future research.
Keywords: Aggregative game, equilibrium (semi-)uniqueness, Fisher–Hahn conditions, marginal reduction, marginal revenue condition, oligopoly.
