“…For example, the theoretical grounding for the traditional 'modified exponential model' lies in an assumption that the temporal path of technology diffusion is made possible by the spread of information from a central source. A variant of the modified exponential model is the logistic model used by Karshenas and Stoneman (1993), Rogers (1995), Geroski (2000), Scitovski and Meler (2002), in which the authors modified the central information source theory by including the input of previous users so that a secondary information source, namely 'word-of-mouth', is incorporated into the model. Using the logistic function of the epidemic model, we attempt to identify the precise patterns of mobile telecommunications.…”
