What factors contribute to the gender wage gap?

• A. Occupational segregation, motherhood penalty, discrimination, differences in work experience and hours, and negotiation dynamics
• B. Biological differences in ability and overall health disparities
• C. Random fluctuations in hiring practices
• D. Wage gaps are solely due to industry-specific policies and have no social components

Answer: (A)

The gender wage gap mainly stems from a mix of social and structural factors that shape how much people earn over time. Occupational segregation means women are concentrated in fields and roles that pay less, with fewer high-paying advancement paths. The motherhood penalty shows up when having children leads to slower wage growth, reduced hours, and gaps in work experience, all of which lower lifelong earnings. Discrimination—both explicit and implicit—slides into pay decisions, contributing to systematically lower wages for women. Differences in work experience and hours arise because caregiving responsibilities and part-time schedules disproportionately affect women, reducing tenure, promotions, and accumulated earnings. Negotiation dynamics matter because norms and expectations around asking for higher pay or raises can disadvantage women, leading to lower initial offers and smaller raises over time.

Biological differences in ability and health disparities aren’t the primary drivers of the broad, persistent gap observed across many occupations. Random fluctuations in hiring practices aren’t systematic enough to explain the wage gap, and saying gaps come solely from industry policies ignores the strong social components like caregiving norms and discrimination that shape pay. The best answer reflects how multiple interconnected social factors collectively contribute to the wage gap.
