		| Shaffer (1991) shows that a multiproduct monopolist selling differentiated products through a unique retailer cannot earn monopoly profit using brand specific two-part tariffs and that full-line forcing restores monopoly power. We extend this analysis to more general contracts and shows that full-line forcing is efficient as it increases both industry profits and consumers' surplus. |
