This study examines how high school employment affects future economic
attainment. There is no indication that light to moderate job commitm
ents ever have a detrimental effect; instead, hours worked during the
senior grade are positively correlated with future earnings, fringe be
nefits, and occupational status. These gains occur even though employe
d seniors attain slightly less education than their counterparts. The
results are robust across a variety of specifications and suggest that
student employment increases net investments in human capital particu
larly toward the end of high school and for females.
