随机定时对策的子对策完美均衡

Subgame-Perfect Equilibria in Stochastic Timing Games

Frank Riedel, Jan-Henrik Steg

摘要:

我们引入了随机时间博弈的子博弈概念和可能的混合策略中的子博弈完美均衡的相关概念。虽然一个很好的概念,子博弈完美均衡的连续时间的游戏是不是在一般情况下,我们认为,我们的模型是合适的版本定时游戏。我们表明,这个概念与通常的离散时间游戏相吻合。许多连续时间的时间博弈只有混合策略的均衡,特别是在战略实物期权文献中经常出现的抢占博弈。我们提供了一个良好的基础,一些主力均衡的文献,这一直缺乏,因为我们显示。我们得到了一个一般的建设性的存在结果子博弈完美均衡抢占游戏,并说明我们的研究结果的几个明确的应用。

英文摘要:

We introduce a notion of subgames for stochastic timing games and the related notion of subgame-perfect equilibrium in possibly mixed strategies. While a good notion of subgame-perfect equilibrium for continuous-time games is not available in general, we argue that our model is the appropriate version for timing games. We show that the notion coincides with the usual one for discrete-time games. Many timing games in continuous time have only equilibria in mixed strategies -- in particular preemption games, which often occur in the strategic real option literature. We provide a sound foundation for some workhorse equilibria of that literature, which has been lacking as we show. We obtain a general constructive existence result for subgame-perfect equilibria in preemption games and illustrate our findings by several explicit applications.
