Blood and Wolfe' s relative resources theory has been cited as an explanation for the well-documented finding that women have typically performed and continue to perform far more domestic labor in their households than men do. This theory holds that power in a family accrues to the spouse contributing the most resources to the household. Such power can be used to withdraw from monotonous housework. Where husbands specialize in income generation, while wives work part-time or are unpaid homemakers, the theory might explain the domestic division of labor. Yet Atkins and Boles found that wives who earn more than their husbands often do most of the domestic labor in their households, and Brayfield found that women whose husbands are unemployed also do most of the housework.
