Daycare home providers care for small numbers of children in the provider’s residence. Many of these providers participate in the Child and Adult Care Food Program, which subsidizes nutrient-dense food served to children in daycare. The effects of this large federal program are little-studied. We estimate the causal effects of the program on daycare home services and prices, leveraging a policy that increased some providers’ food cost reimbursements for identification. Estimation is conducted with unique and richly detailed administrative data. Providers with increased reimbursements increased their supply of child care services as measured by food service, operating schedule length, and variety of shifts. There is weaker evidence of increased child care prices for some child age groups. Large relative increases in offering dinner and evening care are notable, since these are important services for parents working nonstandard schedules. (author abstract)
