We capture these divisions in the model by positing gender-segregated labour markets and women’s association with paid care work. Both women and men contribute to the financial and time costs of providing care, however, just to varying degrees. In our model, investment is of two types: what we term physical investment undertaken by capitalists and human capacities investment undertaken by individuals and households.3 Funds for both types of investment are drawn from national income, which is split between capitalists (profit share) and workers (wage share). Because industries and occupations tend to be highly segregated by sex, we further disaggregate the wage share into the female and male wage shares.
