Long-Term Gains from Longer School Days



This paper examines whether additional time in school affects labor market outcomes and educational attainment in adulthood. We leverage within and across city and cohort variation covering a large-scale reform that increased the Chilean elementary and secondary school day by 30 percent between 1997 and 2010. Exposure to full-day school increases educational attainment and earnings when students are in their 20s and 30s. In addition, we find evidence of delayed childbearing among women, and some occupational upskilling. These labor market effects are not concentrated in any particular subgroup, but are widespread throughout the population. JEL classification: I26; I25; J24; H52
