RT Journal Article SR Electronic T1 Long-Term Gains from Longer School Days JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 0419-10160R2 DO 10.3368/jhr.59.2.0419-10160R2 A1 Dominguez, Patricio A1 Ruffini, Krista YR 2021 UL http://jhr.uwpress.org/content/early/2021/05/04/jhr.59.2.0419-10160R2.abstract AB This paper examines whether additional time in elementary and secondary school affects economic well-being in adulthood. We leverage cross-municipality and cross-cohort variation in a reform that increased the Chilean school day by 30 percent between 1997 and 2010 and find that full-day schooling increased educational attainment, delayed childbearing, and increased earnings when students reached young adulthood. These findings are consistent with a human capital channel and demonstrate large-scale investments in public education can yield long-term economic benefits.
