Uniqueness of Cournot Equilibrium: New Results from Old Methods
给出了古诺均衡存在且唯一的充分条件，不依赖非退化假设，适用于多阶段博弈中的古诺子博弈，比以往结果更广泛。
This paper provides sufficient conditions for the existence of a unique Cournot equilibrium. Previous uniqueness results have depended on an assumption of non-degeneracy of equilibrium. As we illustrate, this assumption often fails in multi-stage games with proper Cournot subgames. Since our uniqueness results do not depend on this assumption, they are more widely applicable.
