Are there no wage returns to compulsory schooling in Germany? A reassessment
重新检验了德国义务教育对工资无回报的结论，发现该结论对样本选择和模型设定敏感，且可能受未考虑的制度细节干扰，因此该结论至少是有争议的。
Summary This study replicates and challenges the finding of zero wage returns to compulsory schooling in Germany by Pischke and von Wachter ( Review of Economics and Statistics, 90(3), 592–598 ), which is unusual in the literature yet widely cited and until now uncontradicted. I document that this finding is sensitive to minor changes in sample restrictions and model specification. Further results suggest that their estimates are potentially confounded by previously unconsidered institutional details. These findings render the conclusion that compulsory schooling in Germany yields no wage returns at a minimum controversial.
