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...

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...

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...

We study the impact of global expansions in mobile internet access between 2000 and 2018 on student outcomes. We link geospatial data on the rollout of 3G mobile technology with over 2.5 million student test scores from 82 countries. Our findings indicate that the introduction of 3G coverage...

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...

In the mid-1980s a movement towards privatization and de-regulation of the telecommunications sector was begun. The sector has been privatized in most countries and subjected to regulatory reform. The major reform occurred in the late 1990s. Since then the internet and cellular-mobile industries...

Many of the critical technologies in knowledge economy are undergoing an exponential rate of rapid improvement. The best known roadmap to guide exponential trend of improvement has been provided by Moore’s law. This paper will update the validity of Moore’s law by applying it to...
