In the DuPont cellophane case, rivals accused DuPont of monopolizing cellophane. DuPont claimed that the relevant market was flexible wrapping material, such as wax paper and aluminum foil, rather than just cellophane. DuPont won the case. What type of evidence constituted DuPont's defense?


DuPont needed to show that other flexible wrapping materials are substitutes for cellophane, which requires a large, positive cross elasticity. DuPont showed that as the price of other flexible wrapping materials increased, sales of cellophane declined substantially, showing a large, positive cross elasticity.
