Abstract
Do consumers react differently to zero prices? We test the presence of a zero-price effect in child health care and find that a zero price is special as it boosts demand discontinuously. A zero price affects resource allocations by encouraging healthier children to use more services and exacerbates behavioral hazard by increasing inappropriate use of antibiotics. A co-payment, of as small as US$2 per visit, alleviates these problems without substantially increasing financial risk. However, a zero price may be used to boost demand for highly cost-effective treatments. Zero and non-zero prices should be strategically chosen to achieve specific goals.

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 it
