Classroom Games: Information Cascades
介绍如何在课堂上设置一个序列决策练习，学生看到私人信号后公开决策，当从众模式出现时即形成信息级联，该练习有助于讨论贝叶斯法则、信息和社会从众行为。
This paper describes how to set up a classroom exercise in which students see private signals and make public decisions in sequence. A pattern of conforming decisions in this context is called an information cascade. Once a cascade starts, it is rational for students to ignore their private signals and follow the pattern of previous decisions. This exercise provides an interactive framework that facilitates discussions of Bayes's rule, information, and social conformity.
