Businesses now exist in a world of rapidly increasing change where innovation has become essential for survival. In this environment successful organisations need to have structures that allow them to predict and respond quickly to such change. Evolutionary economic theories were developed in order to study business dynamics and the role of technological developments in the process of economic growth. The recent economic turmoil has indicated that these theories require updating and a more radical approach is now appropriate. This book compares theories of evolution from economics and the natural sciences in order to better understand the environment in which businesses now operate. New perspectives on business development emerge from the process of unifying theories from both of these domains. This unique research should be essential reading for anyone interested in organisational change, innovation and business success.
