Knowledge Spillover from Information and Communication Technology: A Comparative Study of Australia, Japan, South Korea and Taiwan

This paper analyses the role of information and communication technology (ICT) in Australia, Japan, South Korea and Taiwan within a framework of endogenous growth theory. The focus of this study is ‘knowledge spillover' from ICT. The empirical results suggest that the knowledge spillover from ICT has a strong contribution to the economy-wide R&D; they also suggest that the contribution of ICT to output growth is very limited. These results are consistent with the recent finding that newly introduced technology involves a time lag to contribute to the output growth. As ICT is relatively a new technology, the effects of ICT seem to be still confined only in R&D activities.
