I test, in a field experiment at a flagship state university in the US, whether providing college students salary information can affect their choices of major and classes. I find that undergraduates are substantially misinformed about mean salaries by major. On average, students in my sample underestimate mean salaries, but there is also large heterogeneity in beliefs across individuals. I also find that providing information to correct these errors has a large impact on students’ choices; students in the treatment group were nine percentage points (16%) more likely to major in a field about which they received information.

主要故障：纠正大学生薪酬观念的现场实验

我在美国一所旗舰州立大学的实地实验中测试，向大学生提供薪资信息是否会影响他们对专业和课程的选择。我发现本科生对专业的平均工资有很大的误解。平均而言，我的样本中的学生低估了平均工资，但个人之间的信念也存在很大的异质性。我还发现提供信息来纠正这些错误对学生的选择有很大的影响；治疗组的学生主修他们获得信息的领域的可能性要高出 9 个百分点 (16%)。
