ICT and productivity growth within value chains

Abstract

To what extent have economies become better off because of the diffusion of information and communication technologies (ICT)? We analyze this question based on a growth accounting approach at the level of final output. This approach traces productivity improvements not within sectors but within value chains. It allows judging in a better way to what extent more or better products have become available to final users, in particular consumers, as a result of the diffusion of ICT. A main result is that more than half of the productivity gains related to ICT capital deepening for manufactured goods are contributed by upstream industries. The major part of this contribution is domestic rather than foreign. Moreover, the high sectoral growth in total factor productivity (TFP) in the ICT sector contributes only moderately to TFP growth in non-ICT value chains via the use of intermediates.
