Zusammenfassung: Food Economics provides a unified introduction to the economics of agricultural production, business decisions, consumer behavior, and the government policies that shape our food system. This open access textbook begins with economic principles derived using graphical techniques to explain and predict observed prices, quantities, and other outcomes as a result of individual choices influenced by market structure and public policies. The second half of the book explores available data globally and for the US, covering a wide range of questions in agriculture and economic development, food marketing, and consumption. Food Economics and its accompanying online resources are designed for advanced undergraduate or introductory graduate courses in agriculture, food, and nutrition policy. The book covers the standard diagrams taught in principles-level courses, with concrete examples and practical insights regarding food production, consumption, and trade. Online resources include data sources, and course materials, including slides, exercises, exams, and answer keys. William A.
