Childhood Health and Sibling Outcomes: The Shared Burden and Benefit of the 1918 Influenza Pandemic
NBER Working Paper No. 19505
There is a growing body of evidence showing that negative childhood health shocks have long term consequences in terms of health, human capital formation and labor market outcomes. However, by altering the relative prices of child quality across siblings, these health shocks can also affect investments in and the outcomes of healthy siblings. This paper uses the 1918 influenza pandemic to test how household resources are reallocated when there is a health shock to one child. Using a new dataset linking census data on childhood households to health and education data from military enlistment records, I show that families with a child in utero during the pandemic shifted resources to older siblings of that child, leading to significantly higher educational attainments and high school graduation rates for these older siblings. There are no significant effects for younger siblings born after the pandemic. These results suggest that the reallocation of household resources in response to a negative childhood health shock tended to reinforce rather than compensate for differences in endowments across children.
