A comprehensive evaulation of the impact of SNAP on the health of seniors

Senior participation in the Supplemental Nutrition Assistance Program (SNAP) has traditionally been lower than other groups, with historical estimates below 50 percent. We examine the relationship between state SNAP policy changes occurring over the 2001-2014 period and SNAP participation as well the relationship between SNAP participation and a variety of health-related outcomes for senior and non-senior households.

Racial and ethnic disparities in Covid-19: Evidence from six large cities

As of June 2020, the coronavirus pandemic has led to more than 2.3 million confirmed infections and 121 thousand fatalities in the United States, with starkly different incidence by race and ethnicity. Our study examines racial and ethnic disparities in confirmed COVID-19 cases across six diverse cities – Atlanta, Baltimore, Chicago, New York City, San Diego, and St. Louis – at the ZIP code level (covering 436 “neighborhoods” with a population of 17.7 million).

Estimating the associations between SNAP and food insecurity, obesity, and food purchases with imperfect administrative measures of participation

Administrative data are considered the “gold standard” when measuring program participation, but little evidence exists on the potential problems with administrative records or their implications for econometric estimates. We explore issues with administrative data using the FoodAPS, a unique dataset that contains two different administrative measures of Supplemental Nutrition Assistance Program (SNAP) participation as well as a survey-based measure.

Do Walmart supercenters improve food security?

This paper examines the effect of Walmart Supercenters, which lower food prices and expand food availability, on household and child food insecurity. Our food insecurity-related outcomes come from the 2001-2012 waves of the December Current Population Study Food Security Supplement. Using narrow geographic identifiers available in the restricted version of these data, we compute the distance between each household’s census tract of residence and the nearest Walmart Supercenter.
