1. When Deer Valley Resort CO was developing its ski resort in the Wasatch Mountains it sold parcels of land in the resort village to third parties. Each sales contract reserved the right of approval over the conduct of certain businesses on the property, including ski rentals. For 15yrs DVRC permitted Christy LLC to rent skis in competition with DVRC ski rental outlet. When DVRC opened a new midmountain rental outlet, it revoked Christys permission to rent skis. This meant that most skiers that flew to Salt Lake City and shuttled to Deer Valley had few choices; they could carry their equipment on flights, shuttle to Park City and look for cheaper rentals, or rent from DVRC. Christy filed a suit in Federal court against DVRC. Was DVRC's action an attempt to monopolize in violation of Sherman Act. Why/not? 2. Together emi, sony, bmg, universal, and warner produced licensed and distributed 80% of the digital music old in the US. The companies formed MusicNet to sell the music to online services that sold songs to consumers. MusicNet required all the services to sell the songs at the same price and under same restrictions. Digitization of music became cheaper but MusicNet did not change its prices. Did MusicNet violate the anti trust laws? 3. Dayton Superior Corp sells its products in interstate commerce to several companies including Spa Steel Products Inc. The purchasers often compete directly with each other for customers. From 2005-2007 One of Spa Steels customers purchased Dayton Steels products from two of Spa Steels competitors. According to that customer, Spa Steel prices were always 10-15% higher for the same products. As a result Spa Steel lost sales to that customer and perhaps more. Spa Steel wants to sue Dayton for price discrimination. Which requirements for such a claim would Spa Steel have to satisfy under Sec. 2 of Clayton Act? What will it need to prove?
