Next simulation solutions brand new correlations pre and post beginning to getting constant during the 1969 cohort values. The essential difference between alterations in the fresh new observed pattern and alterations in the original artificial trend rates the share off alterations in pre-delivery correlations to help you full alterations in monetary homogamy, whereas the difference between alterations in the initial and second artificial manner estimates this new share out-of alterations in article-birth correlations to help you full alterations in economic homogamy. For the Desk A3 (on line appendix), i establish show disaggregating these two parts of the newest compositional changes within an assessment of dictate off alterations in virility pricing chatted about after regarding the post.
