As all of our analytical shot is actually single group old 18–49, it is critical to believe whether the family functions out-of apparently older (ages thirty five–49) unmarried someone systematically change from those of its young counterparts for the implies strongly related to the questions. In this instance, the newest lead laws provided with caregiving will be more powerful than brand new indirect signal regarding the sibship status and manage therefore influence how these people are analyzed regarding the matrimony field.
To evaluate the possible implications of such differences, we estimated models restricting the sample to ages 18–34 (Tables A1–A3, online appendix). This restriction does little to change the overall patterns of forces of attraction (Table 1), availability ratios (Table 2), and pairing-specific contributions to changes in TFMRs (Table 3). One difference is in the contribution of each pairing to the observed TFMR and the counterfactual TFMR with forces of attraction held constant for women. Results in panel B of Table 3 show that declining forces of attraction for all pairings involving younger sons account for nearly all the observed decline in TFMR. Results based on the age-restricted marriage market (Table A3, panel B) show that the contribution of pairings involving daughters with brothers is not negligible.
