In this paper we provide non-parametric and parametric estimations of the initial diffusion process of point-of-sale optical scanners that illustrate the importance of controlling for supplier behavior and government regulations. In particular, we show that discrete changes in the early development of the technology followed predictably different diffusion paths depending on each vintage's rela...
