What drives women's rising college graduation rates relative to men's?
Core argument: Parental background accounts for about one quarter of the rise in women's college graduation rate, as children with college-educated mothers have greater tastes for or ability at college, with the effect stronger for daughters than sons.
In recent cohorts, women graduate at much higher rates than men. Our first main result is that changes in parental background are a key factor driving the growing gender education gap: children with college educated mothers have greater tastes for (or ability at) college, and this effect is stronger for daughters than sons. Thus, the increase in women’s education over time has the knock-on effect of increasing daughter’s education relative to sons in the next generation. The marriage market also contributed: women’s chance of getting marriage offers at older ages has improved, making it easier to defer marriage until after college. In contrast, we find that assortative mating did not increase much across the cohorts we study, so this is not an important factor driving the increase in women’s college graduation rate. Labor market returns to college increased in the ’60 to ’80 cohorts, but they increased twice as fast for women as for men. This factor accounts for about 50% of the increase in their graduation rate. Parental background accounts for about 1/4 and marriage offers 1/5.
