Bounding The Effects Of Food Insecurity On Children’S Health Outcomes, Craig Gundersen, Brent Kreider Sep 2009

Bounding The Effects Of Food Insecurity On Children’S Health Outcomes, Craig Gundersen, Brent Kreider

Economics Publications

Previous research has estimated that food insecure children are more likely to suffer from a wide array of negative health outcomes than food secure children, leading many to claim that alleviating food insecurity would lead to better health outcomes. Identifying the causal impacts is problematic, however, given endogenous selection into food security status and potential mismeasurement of true food security status. Using recently developed nonparametric bounding methods and data from the 2001-2006 National Health and Nutritional Examination Survey (NHANES), we assess what can be identified about the effects of food insecurity on child health outcomes in the presence of nonrandom ...


Identification Of Expected Outcomes In A Data Error Mixing Model With Multiplicative Mean Independence, Brent Kreider, John V. Pepper May 2009

Identification Of Expected Outcomes In A Data Error Mixing Model With Multiplicative Mean Independence, Brent Kreider, John V. Pepper

Economics Working Papers (2002–2016)

We consider the problem of identifying a mean outcome in corrupt sampling where the observed outcome is a mixture of the distribution of interest and some other distribution.We make two contributions to this literature. First, the statistical independence assumption maintained under contaminated sampling is relaxed to the weaker assumption that the outcome is mean independent of the mixing process. We then generalize this restriction to allow the two conditional means to differ by a known or bounded factor of proportionality. Second, in the special case of a binary outcome, we consider the possibility that draws from the alternative distribution ...
