Abstract
The objective of this study is to evaluate the technical efficiency of Brazilian companies that operate in the international market of animal protein (beef, pork and poultry). The six business groups of interest are JBS – Friboi, BRF – Brasil Foods, Marfrig, Minerva, Minupar and Excelsior. We fit a production function for the oligopoly assuming a stochastic frontier model with technical effects affecting the inefficiency component. The data are from the consolidated balance sheet of the group for the period that starts in the first quarter of 2007 and ends in the third quarter of 2011. Overall, Brasil Foods shows the worst performance. The stocks of living animals (beef, pork and poultry) negatively affect the production function and the subprime crisis negatively affects the technical efficiency of production.

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
