Employer-sponsored health insurance and the gender wage gap.

During prime working years, women have higher expected healthcare expenses than men. However, employees' insurance rates are not gender-rated in the employer-sponsored health insurance (ESI) market. Thus, women may experience lower wages in equilibrium from employers who offer health insurance to their employees. We show that female employees suffer a larger wage gap relative to men when they hold ESI: our results suggest this accounts for roughly 10% of the overall gender wage gap. For a full-time worker, this pay gap due to ESI is on the order of the expected difference in healthcare expenses between women and men.
