    ICT intensity and New Zealand's productivity malaise: Is the glass half empty of half full?
    (Massey University., 2005) Engelbrecht HA; Xayavong V
    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.

    The elusive contribution of ICT to productivity growth in New Zealand: Evidence from an extended industry-level growth accounting model
    (Routledge, 2007) Engelbrecht HA; Xayavong V
    This paper explores the impacts of Information and Communication Technologies (ICT) on economic growth in New Zealand. Using an extended industry-level growth accounting model to analyse the proximate sources of growth in per capita output, we focus on differences in total factor productivity (TFP) growth and its sub-components, as well as other major components of labour productivity (LP) growth, that emerge between ‘more ICT intensive’ and ‘less ICT intensive’ industries. Employing, alternatively, gross output and net output data, we find great differences and distinct patterns in the growth contributions of the two types of industries. However, the quest to find evidence of positive ICT impacts is still somewhat elusive. Although TFP growth of more ICT intensive industries has steadily increased in importance over time, ‘pure’ or within-industry productivity effects are smaller than structural change effect, and LP growth has only accelerated in recent years. © 2007 Taylor & Francis.
