We y to money inequality into bits on account of alterations in economic homogamy both before and after parenthood, and we also disaggregate this new section in each of these parts one are determined because of the alterations in ladies a position.
Building for the previous books, i come to a few requirement concerning the people regarding changes in couples’ economic homogamy anywhere between 1968 and you will 2015. Basic, i expect that changes in spouses’ monetary resemblance immediately after parenthood tend to play a major part from inside the describing grows for the couples’ monetary homogamy and will also be mainly motivated of the changes in ladies’ a position.
