Abstract
In this paper, we use a longitudinal data set that follows three thousand children in Vietnam to study the economic significance of childhood poverty–cognitive achievement nexus. Focusing on the consequences of stunting, we look at height-for-age z-score (HAZ), and trace the impact of HAZ on child cognitive achievement independent of the source of HAZ’s variation - whether it comes from the variation in child characteristics at birth and the environmental factors, or in the household characteristics (stature, socioeconomic status, etc.). An increase by a standard deviation of HAZ at the age of one expectedly leads to an increase by one fourth of a standard deviation of the log score in a widely-used test of language ability at the age of five. For a quantitative cognitive achievement test, the corresponding figure is 0.20. Our evidence suggests that some of the disadvantages in socioeconomic status are being transmitted across generations.

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
