Abstract
We present a simple microeconomic behavioral model showing that decreases in the price of energy‐dense foods increase body weight if the price of obtaining a calorie from dense food is lower than that of less dense food. Estimates of the determinants of adolescent BMI suggest that the price of high‐density food is negatively related to BMI whereas the price of low density food is positively related. Restaurant availability is not associated with weight, but increases in supermarket density predict lower weight. Quantile regressions show that most of the changes in body weight occur in the top quintile of the conditional distribution of BMI.

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
