Once about Knowledge and knowledge systems, especially knowledge applied to economic development, but since I retired branching into politics, music and whatever catches my attention.
Macroeconomic studies suggest that the internet and mobile phones boost growth. The effect is bigger in developing countries than developed ones, due to the paucity of existing communications infrastructure. The effect also seems to be bigger for the internet than for mobile phones. In a study published in 2009, Christine Zhen-Wei Qiang of the World Bank found that an increase of ten percentage points in mobile-phone adoption increased growth in GDP per person by 0.8 percentage points in a developing country, and by 0.6 percentage points in a developed one. For dial-up internet access, the figures were 1.1 percentage points and 0.75 percentage points respectively; for broadband internet, 1.4 percentage points and 1.2 percentage points.
