Le marché des transporteurs aériens canadiens : une étude clinique en organisation industrielle
Bibliographic record
Abstract
Très peu d’études cliniques existent en économie, et encore moins sur l’économie canadienne. Nous proposons ainsi une étude clinique qui s’utiliserait dans le contexte d’un cours avancé en organisation industrielle, et plus particulièrement dans le cadre d’une série de séances de cours sur la concurrence à la Cournot, à la Bertrand et à la Stackelberg. Nous utilisons la faillite du transporteur aérien Jetsgo en 2005 pour regarder l’impact à court terme sur la valeur marchande des deux autres transporteurs aériens au Canada, Air Canada et Westjet. La présente étude clinique permet de prendre en considération la structure du marché du transport aérien de passagers au Canada pour expliquer la réaction du marché boursier. L’étude développe des modèles économiques simples de concurrence à la Nash-Cournot et à la Stackelberg pour voir lequel explique le mieux le marché intérieur canadien du transport aérien suite à la disparition d’un joueur important.

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.
