Forward Induction in the Battle of Sexes Games
通过实验检验前向归纳作为精炼准则的有效性，发现外部选项的存在虽改变了博弈行为，但对前向归纳假说的支持有限，且外部选项的效果部分源于其创造的焦点效应。
This paper provides experimental evidence on forward induction as a refinement criterion. In the basic extensive form, one of the two players chooses to play a battle-of-the-sexes game or to receive a certain payoff. According to forward induction, choosing to play the game is a signal about intended action. Though the presence of the outside option changes play, the authors find only limited support for the forward-induction hypothesis. The effects of the outside option also reflect the creation of a focal point through the asymmetry created by offering the outside option to one of the two players.
