Human Capital and Personal Income Distribution", JPE 66, 281-302 spells a model of education
as an investment, where human capital H equals
H = AeBeduc
where educ is educational attainment, 3 is the return to an investment of the annual earnings
amount (that gives you an extra year of education, and so increases human capital), and A
includes all other factors influencing human capital. If one unit of H can be rented by a firm
at price P, a person with capital H gets wage H x P:
log (wage) = log P + Beduc + log A.
Using the data on workers' wages, education, experience, etc. from the Stata file wage1.dta
(taken from the 1976 Current Population Survey), run a regression of the logarithm of wage on
the education and tenure. Interpret and critically assess your results. Pay attention to possible
biases.
