Data and Code for "Efficiency Versus Equity in the Provision of In-Kind Benefits: Evidence from Cost Containment in the California WIC Program"

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, for whom distance-related or program learning costs may be high. Thus, cost containment reforms may have unintended consequences of inequitably reducing program access.<br>
