Tying Monopolies Can Profit Through Pricing Discrimination, Enhancing Efficiency Legally.
The article discusses how tying, a business practice where products are sold together, can enhance efficiency and is legal because it can only make profits through pricing discrimination. The Chicago School argues that monopolizers cannot profit in two markets through tying. Other economists have different models that show the flaws in the Chicago School's theory, but the rationality of tying arrangements is still highlighted.
