How can we best understand the impact of revolutionary technologies on the business cycle, the economy, and society? Why is economics meaningless without history and without an understanding of institutional and technical change? Does the 'new economy' mean the 'end of history'?These are some of the questions addressed in this authoritative analysis of economic growth from the Industrial Revolution to the 'new economy' of today. Chris Freeman has been one of the foremost researchers on innovation for a long time and his colleague Francisco Louca is an outstanding historianof economic theory and an analyst of econometric models and methods. Together they chart the history of five technological revolutions: water-powered mechanization, steam-powered mechanization, electrification, motorization, and computerization. They demonstrate the necessity to take account ofpolitics, culture, organizational change, and entrepreneurship, as well as science and technology in the analysis of economic growth. This is a well-informed, highly topical, and persuasive study of interest across all the social sciences.
