Consumer acceptance and valuation of beef that has been tested for BSE
Bibliographic record
Abstract
In light of the discovery of BSE infected cattle in Canada in 2003, a number of efforts have been undertaken to ensure the safety of beef produced in Canada. Recent discussion has focused on testing live cattle for the BSE prion. This paper investigates consumer acceptance and valuation of beef from live cattle that have been tested for BSE. Using data from an internet-‐based survey of English speaking Canada, single bound estimates of WTP are measured. Expected WTP is 43 per cent for the entire sample, but ranges from 52 per cent for respondents with a high purchase intention to 28 per cent for those with less than a high purchase intention. Nevertheless, the proportion of respondents who were predicted to purchase a tested beef product was small, and ranged from 21 per cent for the high purchase intention respondents to eight per cent for the low/medium intention respondents. While respondents appear willing to pay for beef that has been tested for BSE, the market for such products is small.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
