本文分析了在成本严格凸的同质产品市场中价格竞争的纯策略Nash均衡(或Bertrand均衡)的存在性,并证明了当产量由需求决定时,这种均衡总是存在的。本文还描述了这种均衡,并表明,如果企业是相同的,这种均衡必然是非唯一的。然而,对于具有非对称成本的公司,它可以是唯一的或非唯一的。
SummaryThe paper analyses the existence of pure strategy Nash equilibrium in price competition (or Bertrand equilibrium) in a homogeneous product market when costs are strictly convex and proves that if output is demand determined such equilibrium always exists. This paper also characterises such equilibria and shows that if firms are identical such equilibria are necessarily non-unique. However for firms with asymmetric costs it can be unique or non-unique.
