This paper provides structural estimates of a dynamic model of schooli
ng, work, and occupational choice decisions based on II years of obser
vations on a sample of young men from the 1979 youth cohort of the Nat
ional Longitudinal Surveys of Labor Market Experience (NLSY). The stru
ctural estimation framework that we adopt fully imposes the restrictio
ns of the theory and permits an investigation of whether such a theore
tically restricted model can succeed in quantitatively fitting the obs
erved data patterns. We find that a suitably extended human capital in
vestment model can in fact do an excellent job of fitting observed dat
a on school attendance, work, occupational choices, and wages in the N
LSY data on young men and also produces reasonable forecasts of future
work decisions and wage patterns.
