RT Journal Article SR Electronic T1 Efficiency Versus Equity in the Provision of In-Kind Benefits: Evidence from Cost Containment in the California WIC Program JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 0120-10677R1 DO 10.3368/jhr.58.4.0120-10677R1 A1 Katherine Meckel A1 Maya Rossin-Slater A1 Lindsey Uniat YR 2021 UL http://jhr.uwpress.org/content/early/2021/02/03/jhr.58.4.0120-10677R1.abstract AB The government often contracts with private firms to deliver in-kind safety net benefits. These public-private partnerships generate agency problems that could increase costs, but cost-containment reforms may discourage firm participation. We study a 2012 reform of California’s Special Supplemental Nutrition Program for Women, Infants, and Children that reduced the number of small vendors. We show that within-ZIP-code access to small vendors increases take-up among first-time and foreign-born mothers, suggesting that small vendors are distinctly effective at lowering take-up barriers among women with high program learning costs. Thus, cost containment reforms may have unintended consequences of inequitably reducing program access.
