Un MEDAF à plusieurs moments réalisés.

This paper generalizes the Bollerslev and Zhang (2003) approach for the estimation of loadings of asset pricing models using "realized" measures and co-measures of risk. We propose here to extend this approach by including higher-moments in asset pricing models. Estimations are conducted using several methodologies aiming to neutralize data measurement and model misspecification errors, explicity dealing with the inter-relations between financial asset returns. An empirical application performed on a high- frequency French stock price database shows that realized higher-moment measures contribute to improve the global adjustment of the extended model with market data.
