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...

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,...

We study how two distinct types of pre-entry experience – core technological experience and market-based complementary experience – affect post-entry performance in a new industry. We focus on the fit between capabilities generated through pre-entry experience and the preferences of...
