The Importance of Information Targeting for School Choice
在加纳900所初中随机实验中发现，向学生和监护人同时提供择校信息比仅向学生提供更能提升监护人参与度和知情度，对多数结果影响更大。
Although school choice programs are common, we know little about the underlying decision-making processes. In this study, we randomly assigned 900 junior high schools in Ghana, a country with universal secondary school choice, to 1 of 3 treatment arms: (1) information to students, (2) information to students and guardians, and (3) control group. We observe changes in beliefs, behaviors, and the decision maker's identity through a survey of guardians. Our intervention increased the likelihood that guardians were involved with and informed about the school selection process. Moreover, specifically targeting guardians led to significantly larger changes for most outcomes.
