The Administration for Community Living (ACL) was created around the fundamental principle that all people, regardless of age or disability, should be able to live independently and fully participate in their communities.
James Mabli's research focuses on federal nutrition assistance programs, including the Supplemental Nutrition Assistance Program (SNAP), formerly known as the Food Stamp Program; the Special Supplemental Nutrition Program for Women, Infants, and Children; and community-based emergency food programs.
Mabli is the deputy project director for Mathematica’s national evaluation of the impact of SNAP on household food security. He also currently directs several projects related to the dynamics of participants entering and exiting SNAP; the effect of changes in the economy on the characteristics of SNAP participants; and the relationship between low-income household food security and access to retail food establishments and emergency food pantries.
Mabli was the principal investigator of Hunger in America, the largest national evaluation of food insecurity and hunger to date, for Feeding America. He also played a key role in recent projects looking at the relationship between spending on food and diet outcomes for low-income households and the relationship between SNAP caseload trends and changes in economic factors and program policies over the past decade.
Mabli, who joined Mathematica in 2006, has presented at the Southern Economic Association meetings and the Federal Conference of Statistical Methodology. He holds a Ph.D. in economics from New York University.
