Book excerpt: This book provides a useful introduction to evolutionary economics. Adam Gifford, Journal of Bioeconomics With this important collection of fine new papers, Foster and Metcalfe have brought together another volume that will make an impact on the newly unfolding science-of-complexity approach to economics. Ranging from the theoretical foundations to modeling tools and concrete empirical applications, the contributions cover all relevant areas. The reader is being offered exciting new views on variety generating and selecting mechanisms in the economy and their role for technological and commercial change. Ulrich Witt, Max Planck Institute, Jena, Germany Dedicated to the goal of furthering evolutionary economic analysis, this book provides a coherent scientific approach to deal with the real world of continual change in the economic system. Expansive in its scope, this book ranges from abstract discussions of ontology, analysis and theory to more practical discussions on how we can operationalize notions such as capabilities from what we understand as knowledge . Simulation techniques and empirical case studies are also used. Sharpening the focus of the relationship between economic evolution and economic complexity, the book will be of great interest to academics, students and researchers of evolutionary economics.
