“…The relative economic resource model suggests that the more equal husbands' and wives' financial contributions are, the more equally unpaid labor is divided (Coverman, 1985). Some studies have found that when women's incomes are more similar to their husbands, their own housework contributions are lessened, or their husbands' contributions increase (Deutsch et al, 1993;McFarlane et al, 2000;Presser, 1994;Stevens, Minnotte, Mannon, & Kiger, 2006). It is of note, however, that Bittman, England, Sayer, Folbre, and Matheson (2003) found that women's relative earnings decreased their own housework contributions only to the point of equality with their husbands; women whose relative income was more than 50% tended to do more housework.…”
