We study how vertical integration in a two-sided media market affects investments in premium content. We show that a content provider provides the premium content exclusively to a platform, regardless of what the vertical structure of the industry is. However, a vertically integrated content...

We study upstream horizontal mergers and their potential efficiency gains. We show that an upstream horizontal merger can give rise to two efficiency-enhancing effects when firms trade through two-part tariffs. It increases R&D investments and decreases wholesale prices when downstream...

We study the incentives for horizontal upstream mergers in a quantity-setting vertically related industry, under bargain and endogenous contract types. We show that the contract types used could have important consequences for the equilibrium market structure and vice versa. If it is the...

This chapter surveys the legal and economic literatures on the antitrust analysis of tying arrangements and exclusive dealing contracts. We review the analytical framework applied under U.S. antitrust law to tying, bundling and exclusive dealing arrangements as well as the existing theoretical...

This paper evaluates current antitrust policy in light of our current understanding of how transaction costs influence the ability of firms and consumers to deal with market power. The paper shows how the failure to consider transaction costs can lead to erroneous policy decisions. Many models...

In this paper we analyze the problem of the enforcement of incomplete contracts with endogenous outside options. Some of the equilibria we outline may reverse one of the main results presented in the standard literature. We then revisit the literature on the highly debated Fisher Body/General...

When successive monopolies transact through noncooperative linear pricing, the resulting double markup decreases their joint profits relative to vertical integration. However, if there are downstream rivals (which are not double marginalized), the same noncooperative interaction often...

The Rule of Reason, which has come to dominate modern antitrust law, allows defendants the opportunity to justify their conduct by demonstrating “procompetitive” effects. Seizing the opportunity, defendants have begun offering increasingly numerous and creative explanations for their...

Scholars and antitrust enforcers have raised concerns about anticompetitive effects that may arise when institutional investors hold substantial stakes in competing firms. Their concern rests on empirical evidence that such common concentrated ownership is associated with higher prices and lower...
