To what extent are the productivity spillovers of information technology related to R&D activity? Do these factors distinctly affect economic growth, or does the IT impact merely reflect the embodiment of R&D-driven technical progress? Based on country-level data, this work shows that both forms...

Using some new techniques of panel cointegration analysis, this paper describes the long-run impact of digital capital on the aggregate performance of the US and EU-15 member countries. ICT is found to significantly impact on output levels without substantial cross-country variation when one...

By the mid-1990s, the extraordinary advances in semiconductors enhanced the embodied nature of information technology, fuelling the efficiency growth in computers and communication equipment industries. The consequent fall in prices enabled the rapid diffusion of these new technologies, which...

Using data for twelve manufacturing industries of five developed countries over the period 1980-2002, we perform a dynamic panel estimation - based on a ECM model - of the long-run elasticity of TFP with respect to the stock of R&D capital. The highest elasticity is found for the US (0.51) while...

In this paper, a set of knowledge base indicators are used as explanatory variables of the 1995-2002 growth performances of 150 NUTSII regions belonging to ten countries of the former EU15. Their impact is estimated by controlling for the initial levels of the dependent variables, the structural...

By considering a regional sample of Italian inventors, this paper explores the factors behind the different individual performances in terms of number and quality of patents. Our reference population is composed of 570 inventors residing in the Marche region who, over the period 1991-2005, have...
