Abstract
ABSTRACT Market‐based solutions are increasingly tested to address aflatoxin issues in peanuts in developing countries. Although previous studies have found that Haitian grocery store shoppers are willing to pay a 21% premium for peanut butter with levels of aflatoxin that meet international standards, no information is available for the much larger informal market. A stated preference survey, using an iterative bidding process, was conducted among 585 informal market consumers of Port‐au‐Prince and Cap‐Haitien, the two largest cities in Haiti. Results show that informal market participants are willing to pay a 12% premium for peanut butter that meets international aflatoxin standards. Based on the result of a previous revealed preference study on Haitian peanut farmers, the observed premium would be largely sufficient to incentivize farmers to adopt aflatoxin mitigation practices, which supports market‐based solutions to improve the safety of a Haitian staple food. Results also indicate that informal market consumers have greater confidence in a certification from an international institution rather than a domestic one.

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
