Questions: Gender Wage Gap

Question 1

Goldin's research attributes a large portion of the gender wage gap to...

• A. Differences in cognitive ability between men and women
• B. The structure of compensation in certain occupations that disproportionately reward long hours, continuous availability, and schedule inflexibility — characteristics that disadvantage workers with caregiving responsibilities
• C. Women's lower ambition and career commitment
• D. Legal barriers preventing women from entering high-paying occupations

Answer: (B)

Goldin showed that the gender gap is largest in occupations where earnings are convex in hours worked — where working 80 hours pays more than twice as much as working 40 hours. Finance, law, and corporate management exhibit this pattern (a lawyer available 24/7 is disproportionately valued). Women, who bear a disproportionate share of caregiving, are less able to provide this extreme availability. In occupations where hours and scheduling are more flexible and substitutability is high (pharmacy, technology), the gender gap is much smaller.

Question 2

The motherhood penalty refers to the finding that mothers earn less than childless women, while fathers earn more than childless men (the fatherhood premium).

• T. True
• F. False

Answer: True

The motherhood penalty is one of the most robust findings in the gender wage gap literature. Mothers experience wage losses of approximately 5-7% per child, driven by reduced hours, career interruptions, shift to more flexible but lower-paying jobs, and potential employer discrimination against mothers. Fathers, by contrast, experience a wage premium — possibly reflecting selection (more career-oriented men become fathers), employer bias (fathers are perceived as more stable/committed), or increased effort to provide. This asymmetric effect of parenthood is a major driver of the within-gender and between-gender wage gap.

Question 3

If the gender wage gap were entirely due to women's free choices about occupation and hours, would there be no policy concern?

Model answer: Not necessarily, because 'free choice' is shaped by social norms, institutional constraints, and asymmetric expectations. If women disproportionately choose flexible, lower-paying work because they face social pressure to be primary caregivers, because workplaces penalize caregiving-compatible schedules, or because employer discrimination channels them into certain roles, then the choices are constrained rather than free. Furthermore, workplace structures that reward extreme hours may be inefficiently designed — Goldin argues that reducing the premium for inflexible schedules (through better technology, task sharing, and organizational redesign) could narrow the gap without requiring women to work like men.

This is a critical conceptual distinction. Human capital explanations ('women choose different occupations') and discrimination explanations ('women are excluded or underpaid') are not mutually exclusive. The choices women make about education, occupation, and hours are themselves influenced by expected discrimination, social norms about caregiving, and workplace structures that were designed around a male breadwinner model. Disentangling free choice from constrained choice is one of the deepest challenges in gender wage gap research.
