Abstract
I use differences in educational attainment by birth cohorts to estimate the rise in the return to education in the United States. If average ability is similar among nearby cohorts, then differences in educational attainment lead to differences in earnings only if education is productive. The results reveal that (i) the return to a year of schooling increased from 4.8 percent to 8.4 percent between 1964 and 2003, (ii) the ability bias rose from 1.8 percent to 4.7 percent during the same period, and (iii) the acceleration in the education premium after 1980 is explained almost entirely by the rise in the ability bias.

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
