| Bass (1969) developed a growth model for the timing of initial purchase of new products and empirically tested it against data of eleven consumer durables. The basic assumption of his model is that the probability of purchase at any time is related linearly to the number of previous buyers. The model implies exponential growth of initial purchases to a peak and then exponential decay. Innovative and imitative behavior is the underlying behavioral rationale for the model. According to Bass Innovators are individuals who decide to adopt an innovation independently of the decision of other individuals in a social system.

[page 216] Some individuals decide to adopt an innovation independently of the decisions of other individuals in a social system. [page 226] Conclusion The growth model developed in this paper for the timing of initial purchase of new products is based upon an assumption that the probability of purchase at any time is related linearly to the number of previous buyers. There is a behavioral rationale for this assumption. The model implies exponential growth of initial purchases to a peak and then exponential decay. |
