This book is an analysis of the economic effects of the ICT revolution, and answers a few key questions: Did the ICT revolution contribute to the recent divergence in the growth record? And if this is the case, how and why were some countries better equipped to exploit the potential of ICT? It assembles the work of two teams of leading economists, focusing on the role that the ICT revolution has played in advanced countries, and assessing whether or not the digital economy will indeed result in a more competitive and more equal world.
