RT Journal Article SR Electronic T1 Effects of the Child Protection System on Parents JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 0424-13537R2 DO 10.3368/jhr.0424-13537R2 A1 Grimon, Marie-Pascale YR 2026 UL http://jhr.uwpress.org/content/early/2026/04/01/jhr.0424-13537R2.abstract AB Child protective services investigate a third of child-homes for maltreatment, yet repercussions for parents remain unclear. I show that mothers face considerable adversity when referred for alleged child maltreatment. Using a novel strategy that combines event studies with variation in intervention tendency across investigators, I find that child protective services interventions increase mothers’ enrollment in mental health and substance abuse treatment services for a year, even when those services are not mandated. Earnings and employment are unaffected. Marginal interventions can lead to persistent involvement with social services for years.
