What Does it Take to Eliminate the use of a Strategy Strictly Dominated by a Mixture?
通过实验研究被试能否学会停止使用一种被混合策略严格占优但可能成为高于平均回报的策略,发现最有效的处理是使用二元彩票加金钱奖励并给予充分经验,最终将使用率降至约10%。
Abstract This paper reports an experiment to determine whether subjects will learn to stop using a strictly dominated strategy that can be an above average reply. It is difficult to find an experimental design that eliminates the play of the strictly dominated strategy completely. The least effective treatment used money to motivate behavior directly. The most effective treatment used a binary-lottery with money prizes to induce preferences, but even this treatment required giving subjects plenty of experience. Doing so reduced the play of the strictly dominated strategy to around 10 percent by the end of a session. There is no evidence for the explosive cycling needed to make the strictly dominated strategy an above average reply.
