Telecommunication Infrastructure Development and Economic Growth: A Panel Data Approach

Abstract

The present study empirically investigate the dynamic relationship between telecommunication infrastructure and economic growth, using data from twenty-four low income, middle income and high income countries for a 18 years period, from 1985– 2003. With a panel data set, this study uses dynamic fixed effect and random effect models for estimation, which allows us to test the relationship between country’s economic growth with initial economic condition, fixed investment, population growth, government consumption as well as telecommunication infrastructure. The results show that telecommunication is both statistically significant and positively correlated to the real GDP per capita of these countries included in the study. The results are robust even after controlling for investment, population growth, past level of GDP per capita and lagged growth. The results further indicate that the telecommunication investment is subject to increasing returns, suggesting thereby that countries gain more and more with the increase in telecommunication investment. The second test, Granger’s causality test confirms the causal relationship between telecommunication infrastructure and economic growth, but the relationship is significant from telecommunication to GDP per capita side but insignificant on GDP per capita to telecommunication development side.Telecommunication Growth, Panel Data, Fixed and Random Effect, Granger Causality
