Over the past years, the Statistical Working Party of the OECD Industry Committee has dealt with
several different aspects of productivity measurement and analysis. One of these issues was the impact of
using different price indices for constructing volume output measurements of information and

often leading to widely diverging profiles of ICT price indices. As a consequence, international
comparability of trends in volume output measures of certain industries but also volume measures of final
demand components can be hampered
