This work uses economic theory, simple probability, statistical concepts and game theory to analyze the economics of professional sports. It treats sports leagues as cartels and uses historical examples to test theories regarding labor economics. Many key issues that have sparked raging arguments among fans and writers are addressed, including free agency's effect on competitive balance, how rising player salaries have/haven't affected ticket prices, and the effect of a new stadium on the local economy, among many others.
