In this paper, I present global evidence on the impact of expansion in mobile telephony and broadband Internet services on economic development at the subnational level. Leveraging two decades of satellite data on nightlights and the global expansion of 2G and 3G mobile networks in 3419...

This paper examines to what degree trade, FDI and migration promote cellphone usage in developed and developing countries. Since the usage of cellphones requires the installation of costly infrastructure, I analyze the intensive and extensive margin of cellphone diffusion separately. Estimating...

The current problems in mobile telephony are leading critics to make overly pessimistic predictions that 3G - the third-generation mobile phone system - will never become profitable. However, the resulting calls not to introduce 3G and instead directly back alternative wireless technologies...

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...

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...
