In this book the processes of agricultural production and their management are described in terms of activity analysis, since this permits integration of theory with practical evaluations. Analytical tools developed in the book involve the construction of spreadsheet models, and readers are able to construct their own PC spreadsheets from the book's examples and case studies. Economic principles are presented that will assist in improving the design of agricultural processes and technologies, in guiding their appropriate combination in a business setting, and with the making of decisions through time and in recognition of noncertainty. Activity analysis models that allow the design and combination of agricultural activities to be optimized are also discussed. The book is aimed at advanced students of agricultural economics, business and management.
