Return to the stratified regressions of table 14.4.

(a) Compare the predicted earnings associated with different levels of schooling for men and women. Are there particular levels of education at which the earnings for men diverge most dramatically from those for women? If so, what are they? What might explain these patterns?

(b) Use equation (13.22) to estimate the ages at which total returns to age are greatest for men and for women. How do they compare?

(c) In our discussion of equations (13.55) and (13.56), we conclude that earnings for black and nonblack women are statistically indistinguishable.

Does the female regression support or contradict that conclusion? Why?

(d) The slopes for the five dummies identifying racial or ethnic identity in the female regression are all negative, but much smaller in magnitude than in the male equation. What might explain the difference?
