The notion of circular cumulative change - which has been discussed by figures such as Gunnar Myrdal, Thorstein Veblen and K. William Knapp - is often associated with economic development and suggests that once a direction of change is set it will continue. This principle (commonly abbreviated as CCC) might be one of the most undervalued, underused, and under-cited concepts of non-equilibrium economics. The goal of this book is to re-instate the CCC as a key-concept of evolutionary economics, ecological economics, development economics, growth theory, and modern political economics.The contributors to this volume present new research on CCC. This research is either applied economic research using CCC as an analytical framework, or new research on new unpublished archival material on the origin of CCC. Thereby, the book aims at providing a basis for integration of diverse strands of research, providing a sound conceptual foundation for the further development of non-equilibrium economics. This thought-provoking collection - including endeavours from such leading economists as Richard Holt and Steven Pressman - will be of interest to every thinking economist - particularly those inclined toward political economy, the history of economic thought and development economics.
