Abstract The division of labour remains persistently gendered, in particular among couples with children. Previous research shows that women’s lower economic resources are an important factor driving these inequalities, but because gender and (relative) earnings are highly correlated in male–female couples, their relative importance is difficult to disentangle with observational data. Using a factorial survey conducted among approximately 700 employed men and women of childbearing age in Sweden, the United Kingdom, and the Netherlands, the contribution of relative earnings and gender in explaining work-care divisions in couples with children is disentangled. The results show that men and women do not differ in their preferences for their own work hours after childbirth, but both prefer the father to work more hours than the mother. Moreover, the combination of own and partners’ preferred hours shows that men and women in all three countries prefer a modified male-breadwinner model after childbirth in scenarios where the male partner earns more or partners have equal earnings. Preferences for egalitarian divisions of labour appear to be slightly stronger in men compared to women and respondents with more egalitarian views on care tasks show less gender-specialization.
