Order Independence for Iterated Weak Dominance
定义了“好弱占优”概念，证明在该概念下消除弱占优策略的顺序不影响结果，并识别了一类重要博弈使好弱占优与弱占优等价，从而弱占优的顺序也不影响结果。
In general, the result of the elimination of weakly dominated strategies depends on order. We definenice weak dominance. Under nice weak dominance, order does not matter. We identify an important class of games under which nice weak dominance and weak dominance are equivalent, and so the order under weak dominance does not matter. For all games, the result of iterative nice weak dominance is an upper bound on the result from any order of weak dominance. The results strengthen the intuitive relationship between backward induction and weak dominance and shed light on some computational problems relating to weak dominance.Journal of Economic LiteratureClassification Number: C72.
