Revising The U.S. Vertical Merger Guidelines: Policy Issues And An Interim Guide For Practitioners, Steven C. Salop, Daniel P. Culley

Georgetown Law Faculty Publications and Other Works

Mergers and acquisitions are a major component of antitrust law and practice. The U.S. antitrust agencies spend a majority of their time on merger enforcement. The focus of most merger review at the agencies involves horizontal mergers, that is, mergers among firms that compete at the same level of production or distribution.

Vertical mergers combine firms at different levels of production or distribution. In the simplest case, a vertical merger joins together a firm that produces an input (and competes in an input market) with a firm that uses that input to produce output (and competes in an output market). …

Cguppi: Scoring Incentives To Engage In Parallel Accommodating Conduct, Serge Moresi, David Reitman, Steven C. Salop, Yianis Sarafidis

Georgetown Law Faculty Publications and Other Works

We propose an index for scoring coordination incentives, which we call the “coordination GUPPI” or cGUPPI. While the cGUPPI can be applied to a wide range of coordinated effects concerns, it is particularly relevant for gauging concerns of parallel accommodating conduct (PAC), a concept that received due prominence in the 2010 U.S. Horizontal Merger Guidelines. PAC is a type of coordinated conduct whereby a firm raises price with the expectation—but without any prior agreement—that one or more other firms will follow and match the price increase. The cGUPPI is the highest uniform price increase that all the would-be coordinating firms …

The Evolution And Vitality Of Merger Presumptions: A Decision-Theoretic Approach, Steven C. Salop

Georgetown Law Faculty Publications and Other Works

This article reviews the formulation and evolution of the Philadelphia National Bank anticompetitive presumption through the lens of decision theory and Bayes Law. It explains how the economic theory, empirical evidence and experience are used to determine a presumption and how that presumption interacts with the reliability of relevant evidence to rationally set the appropriate burden of production and burden of persuasion to rebut the presumption. The article applies this reasoning to merger presumptions. It also sketches out a number of non-market share structural factors that might be used to supplement or replace the current legal and enforcement presumptions for …

Antitrust, Competition Policy, And Inequality, Jonathan B. Baker, Steven C. Salop

Georgetown Law Faculty Publications and Other Works

Economic inequality recently has entered the political discourse in a highly visible way. This political impact is not a surprise. As the U.S. economy has begun to recover from the Great Recession since mid-2009, economic growth has effectively been appropriated by those already well off, leaving the median household less well off. The serious economic, political and moral issues raised by inequality can be addressed through a panoply of public policies including competition policy, the focus of this article. The article describes the channels through which market power contributes to inequality, and sets forth a range of possible antitrust policy …
