Discussion
This research explores the brand new systems from improved monetary homogamy one of hitched partners in america plus the effects ones components getting monetary inequality round the domiciles. Our appeal could have been to research parenthood since a switch process driving manner inside the spouses’ monetary similarity. I hypothesized that the declining results of parenthood towards ladies economic benefits-specifically, because of a position-create play a central role inside growing spouses’ earning similarity. I assess it device near to anybody else, eg assortative mating therefore the decreasing negative effects of wedding into ladies’ a career. All of our efficiency substantiated you to definitely alter following the parenthood starred a central part in the broadening spouses’ monetary homogamy in america, eg following the 1990s. The newest analyses as well as show that changes regarding relationships ranging from relationships and you may ladies work starred a crucial role in the previous several months-a discovering that, in the event in line with historical browse to the women’s a job (Goldin 1988; Kessler-Harris 1982), can be a bit unanticipated given the insufficient current studies directing so you’re able to which options.
