A simple nudge increases socioeconomic diversity in undergraduate Economics
通过随机对照试验，发现向学生发送关于经济学专业的基本信息或强调职业回报的信息，能使第一代大学生选择经济学专业的比例提高5个百分点，从而缩小了社会经济背景带来的差距。
Abstract We assess whether a light‐touch intervention can increase socioeconomic and racial diversity in undergraduate Economics. We randomly assigned over 2200 students a message with basic information about the Economics major; the basic message combined with an emphasis on the rewarding careers or financial returns associated with the major; or no message. Messages increased the proportion of first generation students majoring in Economics by five percentage points. This effect size was sufficient to reverse the gap in Economics majors for first generation students. Suggestive evidence indicates the effects may be driven by first generation students who were not also underrepresented minorities.
