Internships during tertiary education have become substantially more common over the past decades in many industrialised countries. This study examines the impact of a voluntary intra-curricular internship experience during university studies on the probability of being invited to a job interview. To estimate a causal relationship, we conducted a randomised field experiment in which we sent 1248 fictitious, but realistic, resumes to real job openings. We find that applicants with internship experience have, on average, a 12.6% higher probability of being invited to a job interview.

学生毕业后的实习和就业机会：实地实验

在过去的几十年中，高等教育期间的实习在许多工业化国家变得更加普遍。本研究考察了大学学习期间自愿的课内实习经历对被邀请参加工作面试的可能性的影响。为了估计因果关系，我们进行了一项随机现场实验，其中我们向真实职位空缺发送了 1248 份虚构但真实的简历。我们发现，具有实习经验的申请人被邀请参加面试的概率平均高出 12.6%。
