Revisiting Sweden's comprehensive school reform: Effects on education and earnings
重新评估瑞典综合学校改革，发现改革提高了教育年限但平均收入效应小，未发现取消分轨对不同社会经济群体有差异化收入影响，且先前工具变量估计存在向上偏误。
Summary We revisit a Swedish comprehensive school reform first evaluated by Meghir and Palme (2005). This reform increased years of schooling and abolished tracking. We extend the original analysis to the full population and introduce an improved education measure. Our results confirm the original overall finding of small average earnings effects. However, we find considerably larger increases in educational attainment and no evidence of decreased labor earnings for students with high‐educated fathers. Our analysis provides two new important insights: First, we find no evidence that de‐tracking had differential earnings effects across socioeconomic groups. Second, previous instrumental variable (IV) estimates using similar administrative education data are substantially upward biased.
