After deriving an ICT intensity index in order to classify industries into 'more ICT intensive' and 'less ICT intensive', we compare LP growth rates for these two industry groupings. Further, we employ dummy variable regression models, including difference-in-difference models, to more formally test the relationship between ICT intensity and LP growth. The results prove to be sensitive to the time period specified. When breaks in the data series are taken into account, there seems to be support for the view that LP growth of more ICT intensive... |
