This book offers both a retrospective evaluation by the author of his thought and writing over the past two decades and an extension of his work in Redistribution with Growth. Chapters that discuss the structural characteristics of indibidual countries or groups of countries set the stage for a systematic analysis of the internal and external aspects of structural change that affect the design of policy. In successive chapters a set of techniques for analyzing structural change is developed and applied to some of the principal problems of developing countries today.
