Hoynes H, et al. Can targeted transfers improve birth outcomes? Evidence from the introduction of the WIC Program. J Public Econ. Aug 2011;95(7/8):813-827.
This study explored the relationship between participation in the WIC Program and birth outcomes. The authors analyzed whether WIC participation increased the average birthweight and decreased the number of low-birthweight births. Based on the results, WIC initiation raised the average birthweight by 2 grams and raised it by 7 grams among infants born to mothers with low education levels.
