摘要

我们在连续时间和马尔可夫完美纳什均衡的框架内，分析了开采不可再生资源的寡头垄断的结果是否能被相关垄断复制的问题。我们建立了必要条件和充分条件，并在某些情况下找到了明确的解决方案。此外，我们还展示了具有外部性的非常简单的模型，这些模型的纳什均衡无法在垄断中复制。

What does a dynamic oligopoly maximize? The continuous time Markov case

We analyze the question of whether the outcome of an oligopoly exploiting a nonrenewable resource can be replicated by a related monopoly, within the framework of continuous time and Markov Perfect Nash Equilibrium. We establish necessary and sufficient conditions and find explicit solutions in some cases. Also, very simple models with externalities are shown which Nash equilibrium cannot be replicated in a monopoly.
