Using Employer Hiring Behavior to Test the Educational Signaling Hypothesis*
检验教育信号假说，发现雇主在招聘中更依赖教育信号，当使用信息更丰富的非正式招聘渠道时，雇主更可能降低教育标准。
Abstract This paper presents a test of the educational signaling hypothesis. If employers use education as a signal in the hiring process, they will rely more on education when less is otherwise known about applicants. We find that employers are more likely to lower educational standards when an informal, more informative recruitment channel is used. We thus reject the hypothesis that education is not used as a signal in the hiring process.
