Household taxation, nonlinear occupations, and gender gaps

Abstract: An enduring source of gender inequality is that some high-paying ("nonlinear") occupations penalize balancing work and household time commitments, as emphasized by Goldin (2014). We ask how household taxation interacts with these occupational differences to shape gender gaps in hours, wages, and occupational choice, and whether these differences materially affect the impact of tax reforms. We address these questions in a structural Roy model of household labor supply with occupation-specific earnings-hours nonlinearities and progressive taxation, calibrated to US data. We find that a balanced-budget switch to separately filed progressive taxes significantly reduces the gender gaps in hours and occupational choice, while the wage gap declines more modestly. These improvements arise because the reform lowers marginal tax rates for secondary earners and raises them for primary earners. By contrast, proportional taxation yields much smaller reductions in gender gaps. In both reforms, the standard labor-supply channel accounts for roughly two-thirds of the overall taxable- income response, while the convex earnings-hours relationship amplifies these effects and explains most of the remainder. Occupational switching contributes little because those who do switch are negatively selected.
