  • Pentland-Computational-Antitrust
    ARTICLE Time for a New Antitrust Era: Refocusing Antitrust Law to Invigorate st Competition in the 21 Century Robert Zev Mahari,* Sandro Claudio Lera,** & Alex Pentland*** Abstract. U.S. antitrust laws have repeatedly responded to the changing needs of the nation’s economy. As the marketplace grows ever more data-driven, we find ourselves at yet another critical economic juncture that requires us to revisit antitrust practices to ensure healthy and sustainable competition. In this article, we propose two new antitrust approaches that fit into the existing regulatory landscape, detect signs of anticompetitive behavior early, and handle the unique nature of the digital marketplace. First, we advocate for an expanded definition of monopoly power under the Sherman Act that takes corporate data ownership into account. While current proxies for monopoly power, namely market share and price control, are symptoms of anticompetitive behavior, data ownership is increasingly its harbinger. Second, we advocate for an expanded premerger review process that seeks to prevent nascent competitors from being swallowed up by dominant players, a widespread practice that can be shown to reduce competitiveness. To this end, we leverage new insights from network science and empirical data to anticipate which types of mergers are most likely to have anticompetitive effects. Finally, we propose scalable regulatory strategies to discourage the anticompetitive behaviors we describe in their incipiency, without requiring case-by-case review. * Graduate student, Human Dynamics Group, MIT Media Lab and JD Candidate, Harvard Law School. ** Assistant professor at the Shenzhen-based ETH Zurich-SUSTech Risks-X Institute and visiting researcher at MIT Connection Science and Human Dynamics.

  • Clearing the Deal in the Initial HSR Waiting Period
    the antitrust source Ⅵ www.antitrustsource.com Ⅵ February 2 01 9 1 Nothing to See Here! Clearing the Deal in the Initial HSR Waiting Period Amanda L. Wait and Andrew W. Eklund Over the past ten years, over 83 percent of reportable transactions that have received Second Requests from either the Federal Trade Commission or Antitrust Division of the U.S. Department of Justice have been challenged. 1 Merger review in the United States is taking longe r2 and get - ting more expensive. In the past year, both federal antitrust enforcement agencies in the United States have recognized this increased burden on merging parties and are taking commendable and encouraging steps to address unnecessary burdens on merging parties. One way to elimi - nate the burden of a Second Request, however, is not to get one in the first place. OBy statute, deals that trigger premerger filings under the Hart-Scott-Rodino Antitrust Improve - ments Act (HSR) are usually subject to a 30-day initial waiting period (certain transactions, such as cash tender offers and transactions involving assets in bankruptcy, have a shorter waiting peri - od) during which the parties cannot consummate the pending transaction. 3 At the conclusion of the initial waiting period, 4 the reviewing agency may either close its investigation without further action or seek additional information from the parties in the form of a “Second Request.” A Second Request is a request from the reviewing agency to the transaction parties for documents, data, and other information. The issuance of a Second Request tolls the statutory waiting period under the HSR Act until 30 days after the parties “substantially comply” with the Second Request.

  • The Hart-Scott-Rodino Act: Needing a Second Opinion About Second Requests
    The Hart-Scott-Rodino Act: Needing a Second Opinion About Second Requests MATTHEW S. BAILEY* In 1976, Congress enacted the Hart-Scott-Rodino Antitrust Improvements Act (HSR) to enable the Department of Justice (DOJ)and Federal Trade Commission (FTC) to challenge a merger or acquisition before the transacting companies become inextricably intertwined. By requiring the companies to give the federal antitrust agencies advance notice of the proposed transaction, HSR enables the DOJ and FTC to gather information, analyze potential antitrust issues, and challenge the deal before it is consummated. This Note explores the history and practical consequences of HSR. Specifically, it analyzes the "Second Request" process for obtaining additional information and concludes that the federal antitrust agencies have used the Second Request process as a de facto injunction. This Note examines the costs and benefits of using the Second Request in this manner, addresses potential limitations upon agency power, and concludes that Congress should provide a process of expedited review by a neutralpanel of experts to better approximate congressional intent behind HSR's enactment. I. INTRODUCTION "The sole consistency that I can find is that in [antitrust merger litigation], the Government always wins."1 Justice Potter Stewart's remark * J.D., The Ohio State University Moritz College of Law 2006 (expected); B.S., Miami University 2005. I would like to thank my parents, Dr. Joe and Linda Bailey, and my grandmother, Ora Bailey, for their love and support over the years. I would also like to thank Megan Decker for her never-ending encouragement and patience, as well as the various professors who drew my attention to this topic and sparked my interest in business.

  • Economic Tools for Evaluating Competitive Harm in Horizontal Mergers
    Economic Tools for Evaluating Competitive Harm in Horizontal Mergers Dr. Elizabeth Xiao-Ru Wang, Principal, Charles River Associates, with Practical Law Antitrust, with special thanks to Dr. Gregory Vistnes This Note reviews the various economic tools set out in the Horizontal Merger Guidelines to assess whether and to what extent a merger between competitors is potentially anticompetitve. This is just one example of the many online resources Practical Law Company offers. To access this resource and others, visit practicallaw.com. When a client decides to enter into an acquisition or merger products vary in physical attributes and features. As a result, with a competitor (commonly referred to as a horizontal merger), especially in differentiated product markets, economists tend to the federal antitrust agencies, either the Antitrust Division of the put less weight on concentration measures and investigate other Department of Justice (DOJ) or the Federal Trade Commission factors that consider interactions among different market players.

One or more of the state To evaluate a horizontal merger's competitive effects, both the attorneys general or other regulator, such as the Federal antitrust agencies and the transacting parties often engage Communications Commission, may also review the deal. The economists to apply a range of analytical tools to the available antitrust agencies' key concern in reviewing a deal is whether the evidence.
