Abstract

fetched live from OpenAlex

Dans cet article, nous faisons un survol des modèles d’évaluation des actifs financiers étudiés dans le contexte des marchés boursiers en émergence. Nous soulignons qu’il est plus facile de prévoir les rendements et leur variabilité pour de tels marchés que pour ceux des pays développés, et nous essayons de vérifier si ceci peut être expliqué par l’existence de mesures prévisibles du risque et des primes de risque. À cet égard, nous insistons sur l’importance des tests de changement structurel et des tests diagnostiques pour vérifier si les relations sont stables dans le temps et si des facteurs importants n’ont pas été oubliés. Ces tests sont d’autant plus importants dans le contexte d’un environnement économique et politique d’une plus grande instabilité. Nous terminons par une analyse de l’intégration de ces marchés boursiers en émergence au marché mondial et décrivons un modèle qui permet de capter l’évolution de cette intégration à travers le temps.

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.
