有库存成本的m期双寡头模型,每个厂商选择何时生产。我们发现,与大多数关于企业内生角色的现有工作相反,当m严格大于2时,不存在纯战略均衡。这一结果表明,除了两阶段模型外,不存在稳定的角色分配模式,因此领导者-追随者关系不可避免地变得不稳定。
m-period duopoly model with inventory costs, where each firm chooses when to produce. We find that, in contrast to most existing works concerning endogenous roles of the firms, no pure strategy equilibrium exists when m is strictly larger than two. This result indicates that no stable pattern of allocation of roles exists except for a two-period model; thus the leader-follower relationship inevitably becomes instable.
