Telephone Penetration and Economic Growth in the APEC Region: A Simultaneous Non-Linear GMM Approach

We examine the contributions of the telecommunications infrastructure to economic growth in the Asia-Pacific Economic Cooperation (APEC) economies during the period from 1982 to 2003 using a modified version of the model developed by Roller and Waverman (2001). Our estimation results show that, consistent with Roller and Waverman (2001), telecommunication infrastructure has a significant effect on economic growth in the APEC region and that the inclusion of country fixed effects is important for obtaining a more reliable estimate of the growth effect. Moreover, the magnitude of the growth effect is inversely related to the level of telecommunications infrastructure in the APEC economies. While the marginal effect of an increase in telecommunications infrastructure in the APEC region is smaller than that in the OECD countries found in Roller and Waverman (2001), the total contribution of telecommunication infrastructure to economic growth is larger in the former than in the latter.
