The Effect of Employment while in High School on Educational Attainment: A Conditional Difference-in-Differences Approach
Using American panel data from the National Education Longitudinal Study of 1988, this article investigates the effect of working during grade 12 on attainment. We employ, for the first time in the related literature, a semiparametric propensity score matching approach combined with difference-in-differences. We address selection on both observables and unobservables associated with part-time work decisions, without the need for instrumental variable. Once such factors are controlled for, little to no effects on reading and math scores are found. Overall, our results therefore suggest a negligible academic cost from part-time working by the end of high school. © 2011 Blackwell Publishing Ltd and the Department of Economics, University of Oxford.
