abstract = {This paper investigates how the tying of
complementary products can be used to preserve and extend
monopoly positions. We first show how a firm that is a
monopolist of a product in the current period can use tying to
preserve its monopoly position in future periods. We then show
using related arguments how a monopolist in one market can
employ tying to extend its monopoly position into a newly
emerging market. The analysis focuses on the importance of entry
costs and network externalities. The paper includes a discussion
of antitrust implications.}, }
