    Abstract: This paper investigates the impact of Information and Communication Technologies (ICT) ongrowth in an economy, consisting of three sectors, ICT-producing, ICT-using and non-ICT-using.The benefits from ICT come from the falling prices of the ICT-using sector's good,which is used for the production of intermediate goods. Their falling prices provideincentives for investment for sectors using them, so the non-ICT using sector experiencessustained growth driven by capital accumulation. Rates of growth across the three sectorsdiffer, but the aggregate economy is on a balanced growth path with constant labour sharesacross sectors. US evidence confirms the model's predictions.

    Abstract: This paper provides the first large scale study that examines the impact of both individual- and group-specific factors on the benefits users obtain from their user communities. By empirically analysing 924 survey responses from individuals in 161 Computer Associates' user groups, this paper aims to identify the determinants of successful user communities. To measure success, the amount of time individual members save through having access to their user networks is used. As firms can significantly profit from successful user communities, this study proposes four key implications of the empirical results for the management of user communities.

    Abstract: We survey the micro and macro literature on the impact of Information and CommunicationTechnologies (ICTs) on productivity. The "Solow Paradox" of the absence of an impact ofICT on productivity no longer holds, if it ever did. Both growth accounting and econometricevidence suggest an important role for ICTs in accounting for productivity. In fact, theempirical estimates suggest a much larger impact of ICT on productivity than would beexpected from the standard neoclassical model that we focus on. We discuss the variousexplanations for these results, including the popular notion of complementary organizationalcapital. Finally, we offer suggestions for where the literature needs to go.
    Keywords: ICT, productivity, organisation
