Abstract
Using a unique data set on divorcing couples, we analyze the effects of a change in legal entitlement on the outcomes for divorcing couples. In particular, we analyze the 1997 change to custody provisions in the State of Oregon. Prior to 1997, Oregon assigned custody, based on the discretion of the court, in the best interests of the child. This was changed to a “presumption” of joint parenting, which manifests in the courts encouraging and imposing joint (or shared) custody in cases that otherwise would have had sole custody arrangements. We find that the law had several implications for divorce behavior: different custody outcomes (less sole custody to mothers, more sole custody to fathers), more mediation, longer times until the final divorce, and more acrimonious divorces (more abuse actions filed). We find no evidence that spouses attempted to bargain around the change of legal entitlement.

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
