Extraordinary authorship adds a unique real-world perspective to Commentaries and Cases on the Law of Business Organization. Logical and flexible organization allows for chapters to be taught in any order to accommodate alternative teaching approaches. Rich commentary in the form of explanatory notes facilitates teaching and understanding. Careful case selection and editing presents both classic and important recent cases and an economic-analysis perspective is made accessible through clear and consistent explanatory text.
