This paper introduces a unifying theoretical framework to understand the relationship between different types of communications technology (CT) and the incidence of civil conflict. In our model, one-way CT allows the government to broadcast messages they use to (mis)inform dissidents about the...

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...

This paper analyzes the impact on mobile telephony diffusion patterns of the two predominant payment regimes, calling party pays (CPP) and receiving party pays (RPP), for mobile termination services. By applying instrumental variable techniques to panel data we account for a possible...
