Critical Mass is a common feature of technology diffusion processes. We develop a structural model of demand with network effects to provide a rigorous definition of critical mass as a function of installed base, price and network effects. Using data from the digital cellular telephony market,...

Technology diffusion processes are often said to have critical mass phenomena. We apply a model of demand with installed base effects to provide theoretically grounded empirical insights about critical mass. Our model allows us to rigorously identify and quantify critical mass as a function of...

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 usage intensity? Second, what is the effect of high...
