We study the dynamics of usage intensity of second-generation cellular telephony over the diffusion curve. Specifically …, we address two questions: First, can we draw conclusions about the underlying drivers of technology diffusion by studying …

Cross-country or cross-industry studies of technology diffusion typically estimate how independent factors affect … diffusion speed or timing, often based on a two-stage approach. In many applications, however, countries (industries) differ … most in the saturation level of diffusion. In a novel, single-stage econometric approach to a standard diffusion model, we …
