Abstract
We develop and use an enhanced parity bounds model (EPBM) to examine the discrepancy between the stumpage price administratively determined under Ontario’s current stumpage pricing system and the market value of stumpage covering from June, 1995 to January, 2007. The results show that in the short run, the stumpage prices were below or above the market values. However, in the long run, the underpayment and overpayment will even out each other. The results imply that Ontario’s stumpage pricing system has the ability to capture the full economic rents in the long-run, and the results also have other policy implications. <i>(JEL Q23, Q27)</i>

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
