A welfare analysis of universal childcare : lessons from a Canadian reform
Bibliographic record
Abstract
Leveraging the introduction of universal low-fee daycare in Québec in 1997, we assess the welfare effect of universal childcare provision. First, using novel data on local daycare coverage and a difference-in-differences design, we show that positive impacts on maternal labor supply and childcare use are greater in areas with larger daycare expansion, suggesting that childcare availability, not just affordability, drives these responses. We then estimate the policy's Marginal Value of Public Funds (MVPF), defined as the ratio of beneficiaries' utility gains to net governmental costs. Unlike the standard sufficient-statistics metric, which assumes a marginal change in fiscal policy, we quantify the beneficiaries' utility gains through a model of maternal labor supply and childcare choices. This allows us to relax the common marginal-policy assumption and to incorporate non-pecuniary benefits for parents. Our results indicate substantial welfare gains from universal policies, with approximately $3.5 of benefits per dollar of net government spending - over twice the amount captured by the sufficient-statistics metric. Counterfactual simulations suggest that allocating more resources to increasing availability, rather than improving affordability, could yield even larger social returns.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
