On Ambiguities in the Interpretation of Game Trees
指出Piccione和Rubinstein关于不完全记忆博弈中时间不一致性的论点源于对玩家知识、记忆和重新考虑节点的隐含假设,并提出了一个使这些假设显性化的模型。
Piccione and Rubinstein have pointed out ambiguities in the interpretation of games of imperfect recall. They claim that a player in such a game may be time inconsistent. Here, it is argued that the apparent time inconsistency arises from implicit assumptions regarding what the player knows when he reconsiders his strategy, what he will remember if he changes his strategy, and how the node at which reconsideration takes place is chosen. A model is proposed that allows us—indeed, almost forces us—to make these issues explicit. Once these issues are made explicit, time inconsistency seems less inconsistent.Journal of Economic LiteratureClassification Numbers: C70, D80.
