(3). Desk cuatro means that changes during the ladies’ work played an essential role into the grows from inside the spouses’ economic homogamy pre and post parenthood. Committee A reports outcomes for pre-birth homogamy trend. Consistent with results shown up until now, i note that pre-delivery homogamy improved just in the 1st period, stalling immediately after 1990. step 3 We find that changes in ladies a career account for new totality of your rise in pre-delivery economic homogamy, including 114% into the overall several months and you may 93% in the first several months. That it selecting gives generous support towards assumption you to definitely decreasing bad results of matrimony on the ladies a career try a fundamental piece of the story at the rear of broadening economic resemblance prior to parenthood, especially in consolidation which have causes Dining table 3 showing that newlyweds did not sign up for that it improve. The remaining upsurge in pre-birth monetary homogamy once changing having ladies a position-what we identity the rest of the-normally mirror changes on the relationship regarding ladies’ earnings and you may work to the intensive margin (weeks and you will days did), men’s earnings and a career, and you will assortative mating. Such as, given that women became less likely to want to end jobs completely through to matrimony, they could have become less likely to want to beat performs period otherwise downgrade employment ranking, therefore contributing to expanding money resemblance ahead of parenthood.

Brand new reduction in the character of ladies a position due to the fact a mechanism off expands when you look at the article-birth homogamy (otherwise in contrast, new broadening role of residual-months and period worked, men’s earnings, or assortative mating) indicates that done detachment about labor business played an inferior role recently, in keeping with prior studies (Killewald and you can Zhuo 2015). It influence doesn’t signify every alterations in ladies labor supply starred a smaller sized part. Recall our measure of a job grabs merely nonzero annual money. Various other alterations in labor supply-such as for example, within the annual weeks and you will circumstances regarding performs-was captured on the residual, and these may have been very important drivers regarding alterations in article-birth homogamy in the previous several months.

These types of efficiency as Brest female well as indicate that this new character from changes in ladies employment due to the fact a drivers regarding article-beginning money correlations rejected throughout the years

The brand new broadening importance of the residual may ergo be on account of extended really works instances or full-season work; they elizabeth less likely to want to downgrade to reduce-expenses operate after the parenthood. Research towards the motherhood salary penalty even offers particular help right here, appearing one motherhood wage holes ; Friend and you may Waldfogel 2016).
