This important volume collects together eighteen major essays written by Ryuzo Sato over the last thirty years in the area of growth theory and technical change. After an autobiographical introduction describing Professor Sato's intellectual and personal development, the book presents his early pioneering work on growth models and the relevance of fiscal policy and time in these models. Later essays focus on the application of optimal control theory to growth theory, his work on endogenous growth, endogenous technical change and the development of 'Sato-Beckmann neutrality'.

This landmark book will be welcomed by researchers, teachers and students interested in technical change and progress.
