Identifying Higher-Order Rationality
利用环形网络博弈实验数据，在比现有方法更弱的假设下，估计个体层面的高阶理性水平。结果显示，93%的参与者是理性的，但仅22%持有至少三阶信念。
Strategic choice data from a carefully chosen set of ring-network games are used to obtain individual-level estimates of higher-order rationality. The experimental design exploits a natural exclusion restriction that is considerably weaker than the assumptions underlying alternative designs in the literature. In our data set, 93 percent of subjects are rational, 71 percent are rational and believe others are rational, 44 percent are rational and hold second-order beliefs that others are rational, and 22 percent are rational and hold at least third-order beliefs that others are rational.
