Abstract
Softwood lumber trade between the United States and Canada has worldwide attention due to its economic importance and for lengthy dispute. Most studies have focused on welfare effects of the dispute, while few studies have evaluated the question of likeness of product. This study evaluates the substitutability between U.S. and Canadian softwood lumber including other countries' softwood lumber. Price elasticities are derived from the linear approximation of the Almost Ideal Demand System. The results show that softwood lumber imports to the U.S. from various countries are indeed substitutes for U.S. softwood lumber. The Morishima elasticities of substitution indicate that other countries have a higher degree of substitutability than Canadian softwood lumber.

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
