The effects of SNAP and WIC programs on nutrient intakes of children

Nutritional effects of participation by young children in the Supplemental Nutrition Assistance Program (SNAP) and the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) in the United States are investigated. A system of nutrient equations with dual endogenous programs is estimated by the maximum-likelihood procedure. WIC is found to increase the intakes of three of the four important nutrients for WIC children, including iron, potassium, and fiber. SNAP only has a small and negative effect on fiber intake. The additional benefit of SNAP participation is non-existent given participation in WIC.
