“…At the activity-level, we control for solo parenting (using the “who with” questions to assess whether the respondent engaged in the parenting activity without another adult present) and the hours mothers reported with children (in any activity) prior to the indexed activity. We also control for a total of 14 activity types (following activity coding in Aguiar and Hurst 2007; Kahneman et al 2004; Kalil et al 2012): market-work , carework (exclusive of childcare), cooking , cleaning , shopping , other non-market work , television watching , socializing , education/religious events, eating , basic childcare, playing with children, teaching children, and managing children’s activities and schedules.…”
