Technological Progress and Economic Growth in Sub-Saharan Africa : Evidence from Telecommunications Infrastructure

This paper investigates the impact of telecommunications infrastructure in Sub-Saharan Africa. We use the World Development Indicators database and apply the instrumental variable-generalized method of moments to a panel of 47 countries over the period 1993–2012. The results show that the Internet and mobile phones have contributed to economic growth. A one percentage point increase in Internet and mobile phone usage raises growth by 0.12 and 0.03 percentage points, respectively. Overall, the results suggest that the development of telecommunications infrastructure fosters economic growth in Sub-Saharan Africa.With much room for potential growth enhancement of telecommunications infrastructure, policies to expand access or reduce cost should be strongly encouraged by African governments, particularly as far as the Internet is concerned
