We use administrative data on a sample of births between 1978 and 1985 to investigate the short, medium and long-term consequences of poor infant health. Our findings offer several advances to the existing literature on the effects of early infant health on subsequent health, education, and labor force attachment. First, we use a large sample of both siblings and twins, second we use a variety of measures of infant health, and finally we track children through their schooling years and into the labor force. Our findings suggest that poor infant health is a strong predictor of educational and labor force outcomes. In particular, infant health is found to predict both high school completion and social assistance (welfare) take-up and length.
