Gender Differences in (Some) Formative Inputs to Child Development

While there is a large literature on gender differences in important childhood developmental inputs in developing countries, the evidence for developed countries is relatively limited. I investigate gender differences in some of these inputs in the US and Canada. In the US very low birthweight males face excess mortality compared to their female counterparts. I provide evidence that the previously documented increase in mortality with the withdrawal of critical care at the Very Low Birth Weight (VLBW) threshold is primarily for boys. The fact that the critical care of both boys and girls changes discretely at this threshold suggests a possible misallocation of scarce hospital resources. In the US first born girls are breastfed longer than first born males, but the difference is so small that it is unlikely to have any consequence. Finally, mothers in the US and Canada are more likely to experience depression post birth when the first born child is a boy. Perhaps related, the parenting of first born boys in Canada in the first years of life is more likely to be confrontational.
