We revisit the widely discussed contribution of investment in ICT to economic growth, focusing on differences in productivity and quality of ICT across countries and time. In a growth accounting approach, we look at the way rates of return and rates of asset price decline measure these aspects. Conducting a sensitivity analysis with data from the EU KLEMS database for the years 1990–2007, we introduce a constant rate of return and a constant rate of ICT price decline. Both alternative measurements somewhat downplay the role investment played relative to growth in multifactor productivity in the U.K. and the U.S. during 1995–2000. Moreover, we show that more than half of the ICT contribution to labor productivity growth results from changes in capital quality and composition rather than from quantity.
