Antitrust is back in vogue at the U.S. Supreme Court. Whereas the Rehnquist Court decided few antitrust cases in its latter years (only one from 1993 to 1995, one each year from 1996 through 1999, and none from 2000 to 2003), the Roberts Court issued seven antitrust decisions in its first two...

This paper analyzes the welfare implications of buyer mergers, which are mergers between downstream firms from different markets. We focus on the interaction between the merger's effects on downstream efficiency and on buyer power in a setup where one manufacturer with a non-linear cost function...

Over the past several decades, antitrust law has shifted from predation to exclusion as the predominant competitive risk associated with single-firm conduct. This shift is attributable to the rise of Raising Rivals' Costs (“RRC”) as the modern economic paradigm for understanding the...

In his 2012 article, “Revisiting the Revisionist History of Standard Oil”, Christopher Leslie takes issue with John McGee's work on predatory pricing and its influence on antitrust law and scholarship. Leslie claims McGee's analysis was methodologically flawed, ideologically motivated, but...

The General Court’s annulment of the European Commission’s finding that Intel’s conditional rebate scheme was an abuse of dominance underscores the Court’s readiness to scrutinise in detail the economic analysis, including the so-called as-efficient competitor (AEC) test. This paper...

We provide a novel theory of harm for resale price maintenance (RPM). In a model with two manufacturers and two retailers, we show that RPM facilitates manufacturer collusion when retailers have alternatives to selling a manufacturer's product. Because of the alternatives, manufacturers can only...

Kenya is about to embark on an important reform to expand banking to millions of poor households by enabling third-party retail agents as a low-cost distribution alternative to branches. However, this initiative risks being undermined by the mobile network operator (MNO) Safaricom, which...

This paper analyzes the welfare implications of buyer mergers, which are mergers between downstream firms from different markets. We focus on the interaction between the merger's effects on downstream efficiency and on buyer power in a setup where one manufacturer with a non-linear cost function...

Antitrust scholars have argued that exclusive contracts have anticompetitive, or at best neutral effects, if no efficiencies are generated. In contrast, this paper shows that exclusive contracts can have procompetitive effects, provided buyers are imperfect downstream competitors and contract...

Sports organizations, Hollywood studios and TV channels grant satellite and cable networks exclusive rights to televise their matches, movies and media contents. Exclusive distributions prevents viewers from watching attractive programs, and reduces the TV-distributors incentives to compete in...
