      "fr" => "Le Modèle d'équilibre des actifs financiers (MEDAF) est l'une des pièces centrales de l'enseignement de la finance. Malheureusement ces tests empiriques sont très décevants. Ceci est probablement dû au fait que les bêtas ne représentent pas tous les facteurs de risque rencontrés dans la réalité. Ils ignorent par exemple des effets de taille et de caractère "value des titres". De tels facteurs peuvent être appliqués en supposant que les investisseurs ne sont pas rationnels. Certains auteurs les prennent en compte en les ajoutant au MEDAF traditionnel (voir le " Modèle à trois facteurs " de Fama et French). Une approche plus rigoureuse consisterait à mettre au point un MEDAF comportemental."
      "en" => "The capital Asset Pricing Model (CAPM) has become the centerpiece of financial education. Unfortunately its empirical record is poor mainly because of risk factors distinct from traditional betas. Among them size and value are the two major (but not the only) ones. They can be explained by assuming that investors don't behave rationally. They can be accounted for by adding them to the traditional CAPM (like in the "three factor model"). A more rigorous approach would be to develop a behavioral CAPM"
