Abstract

This paper assesses the growth impact of telecommunications infrastructure investment in developing countries by subjecting country-specific data on mainline tele-density and per capita growth to a Granger causality test within a panel cointegration framework. The results suggest that growth effects vary widely across country groupings reflecting different levels of development. Mainline tele-density and per capita growth strongly reinforce each other for countries that are relatively less developed. The reinforcement effect is even stronger for emerging countries that can be identified by their higher than average growth rates. In contrast, there is, at best, weak evidence of bi-directional causal links between the two variables for countries that are relatively more developed. These differences in the mainline tele-density and per capita growth relationships suggest that investment in telecommunications infrastructure, with its potential to generate high growth return, may serve as the critical tool for driving the growth and development process forward in the less developed countries.
