"This big book is the product of a lifetime of serious and creative scholarship. I can think of no other scholar who has worked more systematically, and with greater dedication, to illuminate the multiple and sometimes elusive aspects of technological change than Vernon Ruttan."--Nathan Rosenberg, Department of Economics, Stanford University"Vernon Ruttan has written an encyclopedic volume on the role of technology in economic growth in both industrialized and poorer countries. The book contains a superb integration of the recent insights of new growth theory and detailed studies of the process of technological innovation at the microeconomic level. The extraordinary scope of the volume ranges from new insights on the extent to which the U.S. consumer price index is affected by technical changeto a detailed examination of the development of the microprocessor. Intensive studies of developments in chemical industries, agricultural technology, and dozens of other industries provide theempirical underpinning for a masterful discussion of induced innovation. This book will be the starting point for all researchers interested in further studies in the area." --Howard Pack, The Wharton School, The University of Pennsylvania"Worthy of a Nobel Prize."-Rondo Cameron, William Rand Kenan University Professor Emeritus, Emory University"A necessary reading for all students interested in economic development."--Peter Chow, The City College of New York
