Abstract
This paper contributes to the conflicting international evidence on the impact of information and communication technology (ICT) on labour productivity (LP) growth. We examine the link between ICT intensity and New Zealand's LP growth in 29 industries over the period 1988-2003, and over relevant sub-periods. After deriving an ICT intensity index to classify industries into 'more ICT intensive' and 'less ICT intensive', we compare LP growth rates for these two industry categories. We also employ dummy variable regression models to more formally test the relationships between ICT intensity and LP growth. The results prove sensitive to the time period specified. When breaks in the data series are taken into account, there is support for the view that LP growth of more ICT intensive industries has improved over time relative to that of other industries, even though overall LP growth was weak. Lack of LP growth per se, therefore, is not necessarily evidence against the beneficial productivity impacts of ICT.
