英文摘要:
In this paper we analyse a dynamic model of investment under uncertainty in a duopoly, in which each firm has an option to switch from the present market to a new market. We construct a subgame perfect equilibrium in mixed strategies and show that both preemption and attrition can occur along typical equilibrium paths. In order to determine the attrition region a two-dimensional constrained optimal stopping problem needs to be solved, for which we characterize the non-trivial stopping boundary in the state space. We explicitly determine Markovian equilibrium stopping rates in the attrition region and show that there is always a positive probability of eventual preemption, contrasting the deterministic version of the model. A simulation-based numerical example illustrates the model and shows the relative likelihoods of investment taking place in attrition and preemption regions.

中文摘要:
本文分析了双寡头垄断中不确定性投资的动态模型,其中每个企业都有从当前市场切换到新市场的选择权。我们构造了混合策略下的子博弈完美均衡,并证明了抢占和消耗都可以沿着典型的均衡路径发生。为了确定磨损区域,需要求解二维约束最优停止问题,我们在状态空间中刻画了非平凡停止边界。我们明确地确定了消耗区的马尔可夫均衡停止率,并证明了最终抢占的概率始终为正,这与模型的确定性版本形成了对比。一个基于模拟的数值例子说明了该模型,并显示了在消耗和抢占区域发生投资的相对可能性。
