Eds. Matilde Mas, Paul Schreyer. During the 1990s, the United States experienced an upsurge in economic growth. Despite the fact that some of this acceleration was of a pure cyclical nature, more long-term structural explanations were also proposed, in particular the role of information and communication (ICT) capital and the production of ICT assets. The contrast between the US#s growth record and the much more modest progress of the European Union (EU) was sometimes interpreted as being the result of the EU#s backwardness in the use and production of assets related to new technologies. If there has indeed existed such a gap and if it explains differential growth performances, this has important political consequences from the point of view of designing strategies for economic growth, such as the ones set out by the EU at the Lisbon and Barcelona summits. Growth, capital measurement and new technologies are the main topics addressed in this book, which is the result of the contributions presented and discussed in an International Seminar organized by the BBVA Foundation and the Valencian Institute of Economic Research (Ivie) in Valencia (Spain) on 25-26 November 2002. All the papers presented there have been updated for this edition. This collection of papers aims to improve our understanding of the driving forces behind economic growth and productivity performance in the 1990s, and specifically the role played by ICT. The book contains ten articles by researchers from Spain (A. de la Fuente, I. Hernando, M. Mas, S. Núñez, F. Pérez and E. Uriel), from Europe (R. Alberts, J. Dupont, J. Melka, L. Nayman, D. Pilat, M. Timmer, P. Schreyer, B. van Ark and F. Vijselaar) and E. Wolff from the United States. The editors (M. Mas and P. Schreyer) summarize the main results in an introductory chapter.
