Third-party certification, food standards and quality assurance in supply chains
Bibliographic record
Abstract
This paper develops a theoretical framework to address and discuss issues of certifier effort, firm size and cost differences in the provision of credible third-party certification services in vertical food supply chains. The emergence of private and voluntary food standards have opened a fast growing market for the provision of independent third-party certification services for a range of credence attributes from origin, through food quality and safety to social and environmental attributes. This study argues that the quality of certification may be affected by the number of heterogeneous standards a certifier is accredited to verify. Moreover, results suggest that the quality of more complex and costly testing protocols and standards resulting in overall higher certification cost may be better served by smaller certification bodies that on average exert higher effort levels. This finding seems of particular relevance to food chain management given the growing proliferation of highly specialized private standards and contractual arrangements in international food supply.

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.
