I y in order to money inequality into the parts because of changes in financial homogamy pre and post parenthood, therefore we disaggregate brand new bit into the each one of these parts that was driven because of the alterations in women’s a job.
Strengthening into the earlier books, we visited two standards in regards to the motorists of changes in couples’ economic homogamy anywhere between 1968 and 2015. Basic, we predict one alterations in spouses’ economic similarity just after parenthood commonly play a major character from inside the explaining develops in couples’ financial homogamy and also be largely driven from the changes in women’s a job. 2nd, we anticipate you to alterations in spouses’ monetary similarity prior to parenthood will play a smaller sized part into the describing increases for the couples’ financial homogamy and that these alter might possibly be motivated a great deal more from the changes in women’s a career models between your start of the relationship and you may parenthood and you will reduced of the changes in assortative mating as mentioned at the start regarding wedding. If our very own criterion are best, we are going to find that alterations in exactly how parenthood molds ladies’ financial benefits to household try a button rider of your own share of economic homogamy in order to inequality around the family.
Investigation, Examples, and you may Actions
Because shown in Desk 1, i explore investigation from around three studies to help you conduct all of our analyses: the 1968–2015 March Newest Inhabitants Surveys (CPS); this new 1960, 1970, and 1980 You.S. ); therefore the 1984–2014 Questionnaire cash and you can System Involvement (SIPP) (U.S. Census Agency 2015).

The fresh CPS includes details about the age of this new oldest youngster regarding the house, which i used to proxy this new timing away from entryway for the parenthood.
Much of our very own CPS analyses rely on a sample of hitched lovers where in actuality the spouse are age forty five or young and its eldest child is years 0–ten (Letter = 333,455 couples).
