Principles of Agricultural Economics, now in its second edition, showcases the power of economic principles to explain and predict issues and current events in the food, agricultural, agribusiness, international trade, natural resource and other sectors. The field of agricultural economics has expanded to include a wide range of important and interesting topics, including macroeconomics, international trade, agribusiness, environmental economics, natural resources, and international development. For this new edition, the text has been updated throughout with a new chapter on policy, separate chapters for supply and demand, and increased coverage of key topics and approaches including finance, trade and behavioural economics.
