Heterogeneity across Families in the Impact of Compulsory Schooling Laws

This paper aims to reconcile diverging results in the literature on the effects of compulsory schooling reforms on earnings. I point out, through a simple model of human capital accumulation, the importance of identifying parental education information to better target the set of potential compliers. Using parental background data, the empirical analysis uncovers the large and positive effects of a French school leaving age reform previously shown to have produced zero and statistically insignificant effects on the earnings of impacted cohorts. The analysis suggests that identifying parental background information is likely a crucial effort in analysing contemporary compulsory schooling policies.
