Modeles mathematiques de base pour la diffusion des innovations

Abstract

The adoption and diffusion of new ideas or new products by a social system has been studied extensively for the past twenty years. A great number of models have been developed to describe the time pattern of the spread of an innovation in such a system. We present in this paper a review of the most important models developed in an marketing purpose. More precisely, we consider the BASS model and some of its extensions. We will expose in another paper [16] generalizations of these models which include marketing variables.
