I use artificial correlation manner off Desk cuatro to demonstrate brand new sum from five vehicle operators of interest: alterations in women’s a job before birth, alterations in income correlation before delivery websites out of changes in ladies a position, changes in ladies’ a position immediately after delivery, and you can changes in earnings correlations immediately after birth online of changes in ladies’ a career.

Shape 2 summarizes the outcomes of investigation for the entire period as well as for the earlier and soon after attacks, 1968–1990 and you may 1990–2015. The top committee suggests this new contribution off alterations in economic homogamy in order to aggregate-peak alterations in money most attractive spanish girl inequality, together with base committee reveals brand new people away from improvement in economic homogamy.

Our very own performance substantiated you to changes following parenthood starred a central part during the broadening spouses’ economic homogamy in the usa, including adopting the 1990s. The brand new analyses in addition to demonstrate that changes throughout the dating between relationships and you will ladies a job starred a crucial role in the last months-a finding that, no matter if in line with historic lookup on the women’s work (Goldin 1988; Kessler-Harris 1982), is somewhat unexpected because of the lack of recent degree leading so you’re able to this options.
