Abstract

fetched live from OpenAlex

L’objet de cet article est d’étudier empiriquement la convergence internationale des marchés des actions, à partir de l’analyse temporelle des primes de risqueex postet, d’identifier dans quelle mesure les composantes des primes permettent d’expliquer ce mouvement de convergence observé sur 11 marchés boursiers durant la période 1984-2007. Pour ce faire, a été développée une approche originale combinant une analyse de la convergence des primes par le biais d’un modèle à coefficients variables et une analyse multidimensionnelle sur données évolutives des composantes des primes de risque. La première méthode permet d’identifier un phénomène de convergence internationale des primes de risque des actions vers le marché américain. Cependant, le processus n’est pas achevé et semble même interrompu pour la plupart des pays européens depuis le milieu des années 1990. En outre, la convergence européenne des primes est clairement établie entre cinq pays européens (Allemagne, Belgique, France, Italie et Pays-Bas). La seconde méthode met en exergue de fortes similitudes entre les marchés des actions européen, canadien et américain, alors que les marchés allemand et suisse se rapprochent davantage du marché japonais.

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.
