On identifying subgame-perfect equilibrium outcomes for timing games
指出Smirnov和Wait(2021)提出的识别时序博弈子博弈完美均衡结果的迭代方法既不必要也不充分,问题在于该方法未完全反映子博弈完美的要求,属于概念性缺陷。
In Smirnov and Wait (2021), an iterative method is devised to identify subgame-perfect equilibrium outcomes of timing games. This note shows by simple examples that the identification is in fact neither necessary nor sufficient. The main issue is that the method does not fully reflect the requirements of subgame perfection, so there is a conceptual and not just a technical problem.
