Abstract

fetched live from OpenAlex

La littérature récente a toujours attribué au phénomène dit de « sélection naturelle » – selon lequel, seules les firmes les plus efficientes survivent alors que les autres sont éliminées par le jeu de la concurrence – un rôle crucial dans la croissance de l’efficience agrégée. En supposant, dans le cadre d’un modèle théorique que les firmes différent non seulement par leurs niveaux d’efficience mais aussi par leurs valeurs de réservation, nous montrons ici que le rôle du mécanisme de sélection dans la croissance de l’efficience agrégée peut être remis en cause notamment lorsque les sortants sont plutôt les firmes les plus efficientes. Un autre résultat important consiste à montrer, qu’à l’équilibre stationnaire, les firmes efficientes et inefficientes peuvent coexister. Ce faisant, le modèle développé permet de rendre compte de la persistance des firmes inefficientes et de la grande dispersion des niveaux d’efficience constatée dans plusieurs études empiriques.

Not 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.
