The book emphasizes the graphical and algebraic analysis of economic outcomes in sport. The book is designed for use in shorter classes: modules of one week or less, summer semester classes, intersession courses, etc. It can also be used as part of a longer, semester long course that includes supplemental readings from journals, magazines, and newspapers.
