Evidence from the literature Previous studies have found mixed results. In general, full-time maternal employment during the first year is associated with poorer child outcomes - especially poorer cognitive outcomes - but effects are small. Evidence from UK and US, in other countries evidence is less extensive.
Aim of the study First international study examining whether early maternal employment matters for outcomes of children of the 21st century. Data: Birth cohort studies in 5 OECD countries: – Australia - The Longitudinal Study of Australian Children (LSAC); – Canada - National Longitudinal Survey of Children and Youth (NLSCY); – Denmark - Danish Longitudinal Survey of Children (DALSC); – UK - Millennium Cohort Study (MCS); – US - Early Childhood Longitudinal Study (ECLS-B)
Data Outcome variables: –Child outcomes: cognitive development, conduct problems and attention deficit. ‘Focal’ variable: –Maternal employment: < 6months full-time, <6 months part-time, 6-11 months, not in paid work by 12 months. Other control variables: –Child characteristics –Mother characteristics –Family characteristics
Results Many mothers are in paid work by child’s first birthday. However, timing and intensity varies across countries.
Results Early maternal employment is weakly linked to cognitive development - association is negative and marginally significant in the UK and the US
Relationship between maternal employment and child cognitive outcomes differs across family types … Coefficients of early maternal employment on vocabulary tests, by family structure Results
… and differs across children with parents with different overall levels of educational attainment Coefficients of early maternal employment on vocabulary tests, by parental education Results
Maternal employment is only one of many factors influencing cognitive and behavioural outcomes, but it is not the most relevant. Promoting parenting activities like reading to children is important for child development. Cautious on drawing policy implications. Further analyses are needed to identify whether results vary by quality of formal care and father’s involvement. Nev Conclusions
