This book explains how changing technology and economizing behaviour induce vast changes in productivity, resource allocation, labour utilization, and patterns of living. Economic growth is seen as a process by which businesses, regimes, countries, and the whole world pass through distinct epochs, each one emerging from its predecessor, each one creating the conditions for its successor. Viewed from a long-run perspective, growth must be characterized as an explosive process, marked by turbulent transitions in social and political life as societies adapt to new opportunities, the demise of old ways of living, and to the vast increase and redistribution of human populations. The book is based on a synthesis of classical economics and contemporary concepts of adaptation and economic evolution. Although it is based on analytical methods, the text has been stripped of all equations and with few exceptions is devoid of technical jargon.

'This new book by Richard Day is a very impressive compilation of research records, spanning a period of forty years or so, by him, his former students, and his research associates. The book shows how he has relentlessly explored economies far from equilibria, and to quote from one of his sentences by 'going against the prevailing disciplinary trends of over-reliance on the concept of equilibrium'. In the book, he emphasizes his conviction that economic optimizing and equilibrium analysis by themselves provide an inadequate mental image of the real world. I am in total agreement with him when he focuses on evolving markets, punctuate equilibria, and endogenously generated structural changes.'

'This well-written book contains Richard Day's achievements in advancing a provocative and interesting point of view toward economics. He asserts that actual economies are never in economic equilibrium, because that implies perfect coordination. Rather, individuals follow habitual routines or attempt to improve their situation through changes based on limited understanding or even act experimentally. Their innovations can cause great harm as well as progress.'

Truman Bewley - Yale University

'The nature of economic change is a mightily important issue that the great body of modern economics has not stressed. This very readable volume introduces 40 years of original work on the dynamics of economic growth by an exceptionally creative economist. Professor Day uses recursive models to synthesize classical, neoclassical, and evolutionary points of view and empirically tests his approach on economic sectors where change is rapid and also on epochal changes in social systems. A great oeuvre by an innovative scholar who is not afraid to think about things in the right way.'

Thrainn Eggertsson - University of Iceland

'In this new work, Richard Day has capped a distinguished career of contributions to the study of adaptive economic systems. He has provided us with a creative synthesis of traditional microeconomics and the analysis of evolutionary economic change.'

Vernon L. Smith - Nobel Laureate, George Mason University

'What Dick Day brings to the growth discussion is an extraordinary combination of breadth of vision and depth of analytical penetration. Readers will experience a sense of intellectual adventure fully appropriate to the grand topic of economic transformation and human progress.'
