本文採用PSID資料庫大量的Sibling樣本以及Fixed effect的計量方法來重新檢驗小孩子在成長過程中的一些家庭事件對其日後教育成果之影響。實証結果有下列幾點異於傳統之發現：(1)父母親的離異對小孩有負的影響，而再婚則有顯著的正的影響，而非如傳統研究所顯示的負影響，(2)媽媽外出工作對小孩日後之教育成果沒有顯著影響，而非如傳統結果的顯著正影響，(3)家庭小孩數與搬家事件對小孩沒有顯著影響，而非傳統研究所顯示的顯著負影響。另外，本文之研究再次加強父母教育程度與所得對小孩日後教育成果之正向影響。

　　　　　In this study we reexamine the association between childhood events and children's later educational achievement by constructing a sibling data set from the Panel Study of Income Oynamics (PSID) survey. Fixed effects models with sibling data are used to control for the unobserved characteristics that drive the outcomes of both childhood events and children's later educational achievements and the correlation among siblings. There are several differences in the findings of conventional estimations and fixed effects estimations. The results from the fixed-effects estimations show that: (1)Children who experienced parental separation and lived extensively in single-parent families had substantially lower educational achievement. Children with a parent who had remarried had substantially higher educational attainment than those with a single parent who did not remarry. (2)Children of working mothers exhibited statistically no difference in educational achievements compared with children whose mothers did not work. (3)The number of siblings and location moves had no significant impacts on children's educational achievements. The correlation between these events and unobserved family heterogeneity might be the causes of the differences.
