When Nutrition Policy Becomes Childcare Policy
This series has followed one policy question from its administrative rule to its provider response: can a CACFP meal reimbursement change the hours and kinds of care offered by small home daycares? The Illinois evidence supports a clear but bounded answer. A higher reimbursement can reach the childcare clock because a qualifying dinner is part of the cost of later care, yet the resulting schedule change is not the same as cheaper care, higher measured quality, more actual meals, or a larger provider market. That distinction is the final judgment readers need in order to evaluate similar nutrition policies without mistaking one outcome for the whole system.
The causal chain is short, but it has several links
The mechanism begins with a payment that is tied to qualifying food. CACFP does not reimburse a provider for an unconditioned hour; it offsets part of the cost of meals and snacks that meet program rules and are served to attending children. Under the Illinois rules studied, the move from the lowest to the highest reimbursement schedule changed the provider's effective food cost across conforming offerings. Because dinner is closely connected to care that runs later in the day, that cost change could alter whether an evening or extended service was worth offering.
The Healthy, Hunger-Free Kids Act supplied the policy variation that made the mechanism testable. Some providers who were all-low in 2009 moved into school mode and the high schedule in 2011 after the rule change and required redetermination. Other providers who began all-low remained there. The study compares the change in reported operations for those two paths, using provider and year fixed effects and checks on pre-reform trends and predetermined outcomes. It is not a randomized trial, but it is more informative than a simple comparison between homes that happened to have different reimbursement statuses.
The response pattern fits the chain. The estimated probability that a provider offered dinner rose by 5.0 percentage points from a mean of 17.3%, a relative increase of 28.9%. The probability of offering an evening shift rose by 5.5 percentage points from a mean of 9.8%, a relative increase of 56.1%. The number of shifts increased by 0.064, and average weekday duration increased by 0.284 hours, which the paper reports as 17.04 minutes. Opening time did not move significantly, while the change was concentrated at the closing end of the day.
Those results are not four versions of the same statistic. Dinner is a food-offering response. An evening shift is a schedule option. Number of shifts measures variety, and duration measures the length of the reported operating day. Their alignment is what makes the food-to-time interpretation persuasive: the reimbursement is associated with changes on the margins where dinner and later care are complements. The absence of significant changes in breakfast, lunch, morning snacks, day shifts, and overnight shifts further suggests a selective response rather than an across-the-board expansion.
School-age summer care provides a related intensive-margin signal. The study finds weak evidence that the probability of offering any summer care rises by 0.100, or 10.0 percentage points, while the number of summer shifts increases by 0.134, a relative increase of 16.1% over its mean. The result is better understood as added variety within an operation than as proof that providers broadly entered a new age category.
The paper reports two conflicting versions of the summer result. Its abstract gives 0.164 for the number of summer shifts, while the introduction, main results, and Table 2 give 0.134.
