If looks could heal: Child health and paternal investment

Area of Science:

• Sociology
• Developmental Psychology
• Public Health

Background:

• Father involvement is crucial for child development.
• Previous studies on father involvement face endogeneity biases.
• The impact of paternal resemblance on child health is under-researched.

Purpose of the Study:

• To investigate the causal effect of father-child resemblance on child health.
• To quantify the impact of paternal time investment on child wellbeing.
• To address endogeneity issues in prior research on fatherhood.

Main Methods:

• Utilized data from the Fragile Family and Child Wellbeing study (first two waves).
• Employed statistical methods to eliminate endogeneity biases (e.g., omitted variable bias).
• Focused on the link between perceived infant-father resemblance and child health at one year.

Main Results:

• Infants resembling their fathers at birth show better health one year later.
• Father-child resemblance increases paternal time investment in positive parenting.
• An additional day per month of father's time investment improves child health by over 10% of a standard deviation.

Conclusions:

• Father-child resemblance positively influences paternal engagement and child health.
• Paternal time investment is a significant factor in improving child health, especially in fragile families.
• The study provides unbiased estimates of father's impact on child wellbeing.
