Klerman and Danielson -- If SNAP had never changed or AFDC-TANF never happened or if economy stayed same, how would food stamp caseload and composition changed? The economy does not change composition of caseload but the caseload would have been smaller without the recession. SNAP and TANF policies change caseload (SNAP increases, TANF decreases) and composition (both do the same thing: less welfare). These three explain half of the change in composition and increased caseload.
Dickert-Conlin, Fitzpatrick, Tiehen -- advertising's effect on SNAP caseload. Radio advertising increased caseload 2.6% ... but not if you include state fixed effects. Spanish TV advertisements lowered caseload (9%), as did online applications (4%). The interaction term Spanish ads * percent Spanish speakers is initially positive, but then goes negative again (at about 1/4 Spanish).
DW (and discussant) - Could it be positive in areas where there are few Spanish-speakers but in areas with a large Hispanic population there are already policies in place to reach out to them so there is little to no effect? Discussant's version relies on network effects.
North Carolina Hunger Project -- Relative to overall population, minorities over-represented in food pantry clients. Food pantry visitors more likely to be female, more likely to have a long-term relationship if on food stamps than if not, and to visit more often if on food stamps than if not. They followed a cohort and found people who get food stamps are likely to have a longer relationship than others (3 months), African Americans have longer relationships (6 mo) and less long if Hispanic (10 mo). Once you enter as an elderly person, you never leave.
