On more macro terms a study by economists at the World Bank examined the impact of various telecommunication modes on GDP of 120 developed and developing countries.

The main highlights of the report suggested:

1. An increase in 10% points in mobile-phone penetration (adding 10 new users per 100 people) increased the GDP per person by 0.8% points.
2. Increase in mobile-phone penetration was more effective than fixed line but less effective than Internet penetration (Dial-up increased GDP of developing countries by 1.1%-points and Broadband boosted it by 1.4%-points)
3. As mobile-phones have the highest penetration, the aggregate impact of mobile-phones is the highest.

Growth effects of ICT, percentage points

Among other country specific studies one conducted by Vodafone concentrates more on how different states in India were impacted by growth in wireless subscribers.

Few key conclusions of the report are:

1. Indian states with higher mobile penetration can be expected to grow faster, for every 10% increase in the mobile penetration, rate the growth rate is expected to be 1.2%-points higher

1. At a threshold of 25% mobile penetration there is a significant impact on economic growth of the state. As of March 2010 all the Indian states had a wireless penetration above 25% with Delhi having the highest at 174% and Bihar the lowest at 26%.

1. It is the level of telecom penetration, and not the growth, which contributes to economic growth. Even though India has the highest growth rate but it still lags behind most comparator countries in terms of teledensity (56% in India).

In all, every telecom technology promotes growth more effectively in the developing world. Perhaps the biggest reason for such a result is that people in developing world are being connected through telecommunications for the first time, compared to developed world where these technologies are just an addition to existing telecom infrastructure.

It’s not incremental, it’s revolutionary here! Whats your take?
