The differential impact of universal child benefits on the labor supply of married and single mothers
Bibliographic record
Abstract
Using a difference-in-differences estimator, we find the Canadian Universal Child Care Benefit (a demogrant paid to families with children under age 6 that was introduced in July 2006) has significant negative effects on the labor supply of legally married mothers but significant positive effects on the labor supply of single mothers. The positive effect for single mothers is concentrated among divorced mothers, with results suggesting divorced mothers’ likelihood of participating in the labor force rises by 2.8 percentage points when receiving the benefit. This contrasts with a reduction in the likelihood of legally married mothers participating in the labor force by 1.4 percentage points. Further, the effects for single moms primarily represent entry to employment and the labor force (extensive margin) and not an increase in hours among those who would have been working without the benefits. The estimated effects for common-law married mothers and single never-married mothers are not statistically significant.

How this classification was reachedexpand
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; a candidate call from one teacher head, not a consensus.
