Education Match and Job Match
利用新数据集发现，资历过高的工人对工作满意度更低且更可能离职，但培训时间与资历过高呈负相关，说明这种看似不匹配的现象可能是最优的。
Using a new data set, this paper gives evidence in support of the intuitive notion that overqualified workers are less satisfied with their jobs and are more likely to quit.However, training time is inversely related to overqualification, which suggests why such seeming mismatches occur and may in fact be optimal.
