Digital technologies and their impact on industry productivity performance

BCR’s digital productivity project
>Digitisation everywhere>We know ICTs had productivity-enhancing effects
in the 1990s– jointly with economic reforms
>Where are we now?
BCR’s Digital Productivity Project
>Productivity growth slower – Aust & RoW>Why?– Fewer ICT/digitally based opportunities?– Opportunities not being realised?– Gains being swamped by other factors?– Gains not being measured?
BCR’s Digital Productivity Project
>Primer released>Update growth accounting– Based on ABS national accounts data
>Case studies>Firm-level econometric analysis>Tackle the hard measurement issues

ICT and capital productivity
Assets:> Land>Buildings>Road vehicles> Inventories
(Very) tentative conclusions
> Growth in use of ICTs has continued in the 2000s> But slowed down after 2007-08
– especially hardware
> Greater use of software in the 2000s> Slower rate of ICT capital deepening on average> Effect of ICTs on productivity of other assets has been
overlooked– high correlation with ICT use in some industries/assets– no improvement in capital productivity in manufacturing
