Do School Resources Matter Only for Older Workers?
利用学校层面和州层面的数据，检验学校支出对学生未来收入的影响是否随年龄增长而变化，发现通常不存在显著的年龄依赖关系。
The literature that examines the impact of school spending on students' subsequent earnings is bifurcated into state-level studies, which typically find strong effects, and school-level studies, which find little effect. Since most of the school-level studies examine young workers, one explanation for the discrepancy is that school inputs benefit workers only as they gain job experience. This paper tests the hypothesis by using both school-level (National Longitudinal Survey of Youth) and state-level data sources (Census and the Biennial Survey of Education). Both data sets suggest that there is typically no significant age dependence. Thus other explanations of the discrepancy are likely to explain the differing results. Copyright 1996 by MIT Press.
