Household Chores, Taxes, and the Labor-Supply Elasticities of Women and Men
We study how the division of household chores and individual preferences contribute to gender differences in labor supply elasticities and examine the implications for optimal taxation. In a model of labor supply in dual-earner households, we show that elasticities and optimal income tax rates depend jointly on gender and the within-household allocation of chores. Using PSID data, we find that chore division substantially affects labor supply elasticities, whereas gender per se plays a smaller role. We then evaluate how well simple, feasible tax rules can approximate the optimal within-household tax structure. Gender-based taxation captures a sizable share of the potential efficiency gains, but gender-neutral rules with realistic levels of progressivity perform better.
