Abstract
Abstract This article assesses the impact on agribusinesses of the United Kingdom Government's announcement of a possible link between Bovine Spongiform Encephalopathy and human health. Three approaches are employed to derive benchmark models against which abnormal returns are estimated, a simple market model, Scholes‐Williams approach, and an autoregressive distributed lag model. Abnormal returns are estimated for single firms and for subsectors over an eight‐day event window. The autoregressive distributed lag model performs best and indicates significant negative abnormal returns in the beef, pet food, animal feed, and dairy sectors and positive abnormal returns in the other meats sector.

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
