I y to help you money inequality into pieces due to alterations in financial homogamy pre and post parenthood, and now we disaggregate new portion within the each of these parts one is driven because of the alterations in ladies employment.
Strengthening for the earlier in the day literature, we come to a few standards in regards to the vehicle operators off alterations in couples’ economic homogamy anywhere between 1968 and you may 2015.

Its a corner-sectional house survey that has been widely regularly studies change during the inequality in the usa. Its well-suited to our studies because has actually highest trials, is sold with money information regarding each other people, that’s uniform around the an extended span of time.
