Contribution empirique au probleme d'agregation de fonctions autoregressives: Le cas de la politique de distribution de dividendes

This paper deals with the aggregation problem of autoregressive functions. The macrocoefficients of the simplified specification are separated into three components, namely, a true value, an aggregation bias, and an implicit sampling error. Relative importance of these components is studied by using empirical data on a sample of 40 Canadian firms. The notion of aggregation gain of Grunfeld and Griliches is also examined.
