We y in order to money inequality to the bits on account of alterations in economic homogamy both before and after parenthood, and we disaggregate the new piece into the all these pieces that try determined from the alterations in ladies’ a position.

Strengthening to your earlier literary works, i started to two expectations towards people off alterations in couples’ economic homogamy ranging from 1968 and you may 2015. Very first, we anticipate that alterations in spouses’ monetary resemblance immediately after parenthood tend to enjoy a major role during the explaining grows during the couples’ financial homogamy and will also be mainly motivated because of the changes in ladies a position. 2nd, i assume you to changes in spouses’ economic similarity in advance of parenthood commonly gamble a smaller part during the describing develops from inside the couples’ financial homogamy and that this type of changes was determined alot more of the changes inside the ladies work habits involving the beginning of the matrimony and you will parenthood and you will smaller from the changes in assortative mating because the mentioned at the start out of relationships.
