More than one hundred years after Thorstein Veblen's famous article 'Why is Economics Not an Evolutionary Science?', Evolutionary Economics is now widely recognized as a highly productive approach offering crucial insights for the understanding of socio-economic processes of change and development. A major feature in the development of Evolutionary Economics is-and has always been-its strong multi-disciplinary character, and this new four-volume collection in the Routledge Major Works series, Critical Concepts in Economics, meets the need for an authoritative, up-to-date, and comprehensive reference work synthesizing this voluminous literature. Indeed, the sheer scale of the research output-and the breadth of the field-makes this collection especially welcome. It answers the need for a comprehensive collection of classic and contemporary contributions to facilitate ready access to the most influential and important scholarship from a wide range of theoretical and practical perspectives. Evolutionary Economics is edited by Andreas Pyka, a leading scholar in the field. The collection is fully indexed and has a comprehensive, newly written, introduction, which places the material in its intellectual context. It is an essential work of reference and is destined to be valued by scholars and students as a vital one-stop research resource.
