Résumé

Cet article vise à tester l'hypothèse Quit-life (QL) dans le secteur bancaire angolais. Pour atteindre cet objectif, une méthodologie basée sur des modèles économétriques a été conçue. Le coût et l'échelle efficaces ont été déterminés à partir du modèle d'analyse de frontière stochastique et pour tester l'hypothèse analysée, des modèles avec des données de panel ont été appliqués et le test de Hausman a montré que les modèles à effets aléatoires décrivent mieux les données angolaises. 22 banques sur les 29 qui ont opéré en Angola, de 2007 à 2019, font partie de l'échantillon de l'étude.
