Using partial identification methods and data from the PSID, we analyze the causal transmission of food security across generations. Food security rates are positively correlated across generations; food security rates in 2015 are 20 points higher for respondents who grew up in households that were secure in 1999 than those growing up in food insecure households. Despite these strong associations, the intergenerational effect of growing up in a food secure household remains uncertain. .
The Women, Infants, and Children Program (WIC) is considered a crucial component of the social safety net in the United States, yet there is limited supporting evidence on the effects of WIC on the nutritional well-being and food security of infants and young children. Two key identification problems have been especially difficult to address. First, the decision to take up WIC is endogenous as households are not randomly assigned to the program; recipients are likely to differ from nonrecipients in unobserved ways (e.g., prior health) that are related to associated outcomes.
