The application of the principles of economics to the production of crops and livestock - and to land usage more generally - is a well-established and flourishing area of research and study, 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 its 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. "Agricultural Economics" is edited by Gail L. Cramer, a leading scholar in the field. The collection is fully indexed and has a comprehensive introduction, newly written by the editor, 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.
