| Abstract: | This paper estimates the influence of broadband infrastructure, which enables high-speed internet, on economic growth in the panel of OECD countries from 1996 to 2007. The instrumental variable model, which is represented in the paper, derives its non-linear first stage from a logistic diffusion model where pre-existing voice telephony and cable TV networks predict maximum broadband penetration. It is found that a 10 percentage point increase in broadband penetration raised annual per capita growth by 0,9-1,5 percentage points. It is verified that instruments which are used predict broadband penetration but not diffusion of contemporaneous technologies like mobile telephony and computers. |
