TY - JOUR T1 - A Sibling Study of Stepchild Well-being JF - Journal of Human Resources JO - J Hum Resour SP - 248 LP - 276 DO - 10.3368/jhr.XXXIX.1.248 VL - XXXIX IS - 1 AU - Eirik Evenhouse AU - Siobhan Reilly Y1 - 2004/01/01 UR - http://jhr.uwpress.org/content/XXXIX/1/248.abstract N2 - Examining 33 indicators of well-being from the National Longitudinal Study of Adolescent Health, we conclude that stepchildren’ s inferior outcomes are not entirely explained by sample selection. Using sibling comparisons to control for unobserved family characteristics, we identify stepparent effects by comparing half-siblings in families in which one child has both parents and the other a parent and stepparent. Most estimated effects retain their sign after differencing across siblings, and a third remain statistically significant. The estimates’ sensitivity to the choice of indicator suggests that studies based on a single measure of child wellbeing may be misleading. ER -
