On identifying subgame-perfect equilibrium outcomes for timing games

Steg J-H. On identifying subgame-perfect equilibrium outcomes for timing games. Games and Economic Behavior. 2022;135:74-78.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
