Abstract
A dumping investigation involves comparing export prices with a "normal value" loosely defined as the price in the exporter's domestic market observed in the course of normal trade. However, domestic sales with prices below production costs are excluded from the computation of a normal value. The paper illustrates how price cycles affect the magnitude of estimated dumping margins. The empirical analysis focuses on Canadian hog exports to the United States and U.S. potato exports to Canada. The estimated period and amplitude of each price cycles result in average dumping margins for Canadian hogs and U.S. potato exports of 11.5% and 5.9%, respectively. Biases in dumping margins depend on the nature of the cycle, the period of investigation, and the average production cost estimate.

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
