ABSTRACT Previous research has documented substantial overqualification and an association with social disadvantage and fields of study. Overqualification persistence has been less studied. Persistence is more important than prevalence because skill and job matches are likely to involve lags. Our data set allows us to estimate the prevalence, the correlates, and the persistence of overqualification among Canadian postsecondary graduates using two different measures. We find: i) substantial overqualification and overqualification persistence; ii) the socially disadvantaged and those with less vocational diplomas were more likely to be overqualified but not more likely to move to a match; iii) mobility and academic performance seem to influence catch-up; iv) choice of overqualification measure has large effects on results.

加拿大毕业生中资格过高的发生率，来源和持续存在

摘要先前的研究已经证明，资格过高和与社会不利因素及研究领域相关联。对资格过度保留的研究较少。持久性比普遍性更重要，因为技能和工作的匹配可能会带来滞后。我们的数据集使我们能够使用两种不同的方法来估计加拿大专上毕业生中的普遍性，相关性和超额资格的持续性。我们发现：i）大量的资格过度和持续性过度资格；ii）社会处境不利者和职业文凭较少的人更有可能获得资格，但更不可能参加比赛；iii）流动性和学习成绩似乎会影响追赶；iv）选择超标措施对结果影响很大。
