When Vertical Is Horizontal: How Vertical Mergers Lead To Increases In “Effective Concentration”, Serge Moresi, Steven C. Salop

Georgetown Law Faculty Publications and Other Works

This article explains the inherent loss of an indirect competitor and reduction in competition when a vertical merger raises input foreclosure concerns. We then calculate a measure of the effective increase in the HHI measure of concentration for the downstream market, and we refer to this “proxy” measure as the “dHHI.” We derive the dHHI measure by comparing the pricing incentives and associated upward pricing pressure (“UPP”) involved in two alternative types of acquisitions: (i) vertical mergers that raise unilateral input foreclosure concerns (and the associated vertical GUPPI measures), and (ii) horizontal acquisitions of partial ownership interests among …

Predictable Punishments, Brian Galle, Murat C. Mungan

Faculty Scholarship

Economic analyses of both crime and regulation writ large suggest that the subjective cost or value of incentives is critical to their effectiveness. But reliable information about subjective valuation is scarce, as those who are punished have little reason to report honestly. Modern “big data” techniques promise to overcome this information shortfall but perhaps at the cost of individual privacy and the autonomy that privacy’s shield provides.

This Article argues that regulators can and should instead rely on methods that remain accurate even in the face of limited information. Building on a formal model we present elsewhere, we show that …

Theorizing Developmental Regionalism In Narratives Of African Regional Trade Agreement, Olabisi D. Akinkugbe

Articles, Book Chapters, & Popular Press

There is a gap in the legal scholarship on African regional trade agreements (RTAs) that links law and development to narratives of developmental regionalism. This article undertakes a critical analysis of the ‘developmental regionalism’ paradigm as they have been applied in the study of African RTAs. The article identifies three areas of critical intervention to address the incoherence of developmental regionalism in Africa: limitation in theory; narrow conceptualization; and an insufficient attention to the role of law. First, to address the gap in theorizing the ‘development’ in developmental regionalism, this article makes the case for an explicit linking of Law …

Overcoming Political Polarization: Federal Funding Of Education Is The Key, Reuven S. Avi-Yonah

Law & Economics Working Papers

The best way of overcoming political polarization in the US (the last two elections were both decided by fewer than 100,000 votes in WI, MI, PA (2016) and WI, AZ, GA (2020)) is to reduce disparities in education. But how can we do that?

The basic problem arises from the US system of funding K-12 education from property taxes. While the picture above refers to college education, it is K-12 education that determines both college admissions and college readiness.

Thus, the only viable solution is a federal solution. As President Nixon proposed in 1972, the United States should adopt an …

Is The Digital Economy Too Concentrated?, Jonathan Klick

All Faculty Scholarship

Concentration in the digital economy in the United States has sparked loud criticism and spurred calls for wide-ranging reforms. These reforms include everything from increased enforcement of existing antitrust laws, such as challenging more mergers and breaking up firms, to an abandonment of the consumer welfare standard. Critics cite corruption and more systemic public choice problems, while others invoke the populist origins of antitrust to slay the digital Goliaths. On the other side, there is skepticism regarding these arguments. This chapter continues much of that skepticism.

Network Effects In Action, Christopher S. Yoo

All Faculty Scholarship

This Chapter begins by examining and exploring the theoretical and empirical limits of the possible bases of network effects, paying particular attention to the most commonly cited framework known as Metcalfe’s Law. It continues by exploring the concept of network externalities, defined as the positive external consumption benefits that the decision to join a network creates for the other members of the network, which is more ambiguous than commonly realized. It then reviews the structural factors needed for models based on network effects to have anticompetitive effects and identifies other factors that can dissipate those effects. Finally, it identifies alternative …

The Costs Of Critical Habitat Or Owl’S Well That Ends Well, Jonathan Klick, J.B. Ruhl

All Faculty Scholarship

When the Fish and Wildlife Service designated land in four counties of Arizona as “critical habitat” necessary for the protection of the endangered cactus ferruginous pygmy‐owl, property values dropped considerably. When the owl was later delisted, property values jumped back up. We use difference-in-difference and synthetic control designs to identify this effect with Zillow property value data. The results provide an estimate of the costs of this critical habitat designation, and they are considerable, contrary to the regulators’ position that critical habitat protection imposes no incremental costs beyond the original endangered species listing.

Afghanistan's New Vat, Part 1: Invoice Matching Or A Unitary Digital Invoice, Richard Thompson Ainsworth, Musaad Alwohaibi, Andrew Leahey, Yujin Li, Haseena Rahman

Faculty Scholarship

In the summer of 1990 two groundbreaking articles on business process re-engineering (BPR) were published, one by Thomas H. Davenport (a professor in information technology at Babson College) in the MIT Sloan Management Review, the other by Michael Hammer (a professor of computer science at MIT) in the Harvard Business Review. BPR is a management strategy that analyzes IT-intensive workflow designs and business processes within an organization.

On December 21, 2020 (Jadi 1, 1399) Afghanistan was scheduled to implement a 10% VAT. It has been delayed one year by the pandemic. When it does implement, Afghanistan will have significant workflow …

The Behavioral Effects Of (Unenforceable) Contracts, Evan Starr, Jj Prescott, Norman Bishara

Articles

Do contracts influence behavior independent of the law governing their enforceability? We explore this question in the context of employment noncompetes using nationally representative data for 11,500 labor force participants. We show that noncompetes are associated with reductions in employee mobility and changes in the direction of that mobility (i.e., toward noncompetitors) in both states that do and do not enforce noncompetes. Decomposing mobility into job offer generation and acceptance, we detect no evidence of differences in job search, recruitment, or offer activity associated with noncompetes. Rather, we find that employees with noncompetes—even in states that do not enforce them—frequently …

Looking Back, Looking Forward: Women In Criminal Justice Task Force, Maryam Ahranjani

Faculty Scholarship

Since the Criminal Justice Section’s Women in Criminal Justice Task Force launched in November 2018, we have heard from women in criminal law around the country about their experiences with (1) hiring, (2) retention, and (3) promotion of women in criminal justice. We set many goals for ourselves, including hosting listening sessions, publishing columns, and collecting data, and we are proud of all we have accomplished over the past nearly two years.

Competitive Harm From Vertical Mergers, Herbert J. Hovenkamp

All Faculty Scholarship

The antitrust enforcement Agencies' 2020 Vertical Merger Guidelines introduce a nontechnical application of bargaining theory into the assessment of competitive effects from vertical acquisitions. The economics of such bargaining is complex and can produce skepticism among judges, who might regard its mathematics as overly technical, its game theory as excessively theoretical or speculative, or its assumptions as unrealistic.

However, we have been there before. The introduction of concentration indexes, particularly the HHI, in the Merger Guidelines was initially met with skepticism but gradually they were accepted as judges became more comfortable with them. The same thing very largely happened again …

In this essay, which formed the basis for the luncheon keynote speech at the Rethinking Stewardship online conference presented by the Ira M. Millstein Center for Global Markets and Corporate Ownership at Columbia Law School and ECGI, the European Corporate Governance Institute, the essential, but not sufficient, role of regulation to promote more effective stewardship by institutional investors is discussed. To frame specific policy recommendations that align the responsibilities of institutional investors with the best interests of their human investors in sustainable wealth creation, environmental responsibility, the respectful treatment of stakeholders, and, in particular, the fair pay and treatment of …

Recovery For Causing Tax Overpayment - Lyeth V. Hoey And Clark Revisited, Douglas A. Kahn, Jeffrey H. Kahn

Law & Economics Working Papers

The question has arisen in numerous cases as to the extent to which a settlement between arms’ length parties is dispositive in tax cases of the claims on which the settlement is based. Another issue that often arises is whether the receipt of compensation for a tax payment that was incurred because of the negligence of the payor is excluded from gross income. While those two issues were central to the proper resolution of a recent case in the United States Court of Appeals for the Eleventh Circuit, McKenny v. United States, the court failed even to note one of …

Expansion Of New Law In Southeast May Stave Off Black Land Loss, Thomas W. Mitchell, Sarah Stein, Ann Carpenter

Faculty Scholarship

Landownership and homeownership are significant contributors to the creation of wealth and thus, drivers of intergenerational economic mobility. However, many people who have inherited family land are unable to realize these opportunities because of the legal effect of their particular form of landownership, often called heirs' property. These landowners are more likely to lose their land through what is known as a partition sale—a property sale resulting from a dispute between co-owners, often ignited by an outside party with an investment interest in the land. This Partners Update article explores the repercussions of heirs' property ownership and examines legislative solutions …

Do Lawyers Need Economists? Review Of Katja Langenbucher, Economic Transplants: On Lawmaking For Corporations And Capital Markets (Cambridge U. Press, 2017), Reuven S. Avi-Yonah

Law & Economics Working Papers

Katja Langenbucher’s outstanding book seeks to address the question of why and in what ways have lawyers been importing economic theories into a legal environment, and how has this shaped scholarly research, judicial and legislative work? Since the financial crisis, corporate or capital markets law has been the focus of attention by academia and media. Formal modelling has been used to describe how capital markets work and, later, has been criticized for its abstract assumptions. Empirical legal studies and regulatory impact assessments offered different ways forward. This excellent book presents a new approach to the risks and benefits of interdisciplinary …

The Comet Framework: Greenhouse Gas Data Transparency To Enable The Success Of Eu Climate Policy, Martin Dietrich Brauch, Solina Kennedy

Columbia Center on Sustainable Investment Staff Publications

To further and fully understand how to plan for the decarbonization of mining value chains, we need better data on carbon and other greenhouse gas (GHG) emissions. However, neither consumers, corporates, or financial institutions know the embodied emissions in the products they produce or sell. While methods like life-cycle analysis and environmental product declarations exist, none use a verifiable, comparable, or widely adopted emissions reporting framework capable of sending supply chain signals.

To truly reform material supply chains, new solutions for markets, capital, and policy are required. COMET (the Coalition on Materials Emissions Transparency)—an alliance launched at Davos in January …

Shelter Mobility, And The Voucher Program, Ezra Rosser

Articles in Law Reviews & Other Academic Journals

What is to be done about the poor and about poor neighborhoods? When it comes to housing policy, the current hope is that the Housing Choice Voucher Program (formerly the Section 8 Voucher Program) can provide an or ambitiously the answer to this perennial societal question. By piggybacking on the private rental market, the voucher program supposedly has numerous advantages over traditional, project-based, public housing. Not only is it less costly to house poor people in privately owned units compared to the cost of constructing and maintaining public housing, but the voucher program also offers the possibility of deconcentrating the …

Redesigning Education Finance: How Student Loans Outgrew The “Debt” Paradigm, John R. Brooks, Adam J. Levitin

Georgetown Law Faculty Publications and Other Works

This Article argues that the student loan crisis is due not to the scale of student loan debt, but to the federal education finance system’s failure to utilize its existing mechanisms for progressive, income-based payments and debt cancellation. These mechanisms can make investment in higher education affordable to both individuals and the government, but they have not been fully utilized because of the mismatch between the current system’s economic reality and its legal, financial, and institutional apparatus.

The current economic structure of federal student loans does not resemble a true credit product, but a government grant program coupled with a …

Whither The Regulatory "War On Coal"? Scapegoats, Saviors, And Stock Market Reactions, Cary Coglianese, Daniel E. Walters

Faculty Scholarship

Complaints about excessive economic burdens associated with regulation abound in contemporary political and legal rhetoric. In recent years, perhaps nowhere have these complaints been heard as loudly as in the context of U.S. regulations targeting the use of coal to supply power to the nation’s electricity system, as production levels in the coal industry dropped by nearly half between 2008 and 2016. The coal industry and its political supporters, including the president of the United States, have argued that a suite of air pollution regulations imposed by the U.S. Environmental Protection Agency during the Obama administration seriously undermined coal companies’ …

Equipping The Nigerian National Petroleum Corporation For The Low-Carbon Transition: How Are Other National Oil Companies Adapting?, Perrine Toledano, Martin Dietrich Brauch, Tehtena Mebratu-Tsegaye, Francisco Javier Pardinas Favela

Columbia Center on Sustainable Investment Staff Publications

The Nigerian National Petroleum Corporation’s (NNPC) persistent governance challenges have both hampered Nigeria’s oil sector development and deprived the country of public resources. The oil, climate, and COVID-19 crises and the ramp-up of the low-carbon transition exacerbate this reality, with the national oil company (NOC) delivering sub-optimal returns to its stakeholders.

Other NOCs have taken meaningful steps to become players in the low-carbon energy transition domestically or in­ternationally – for example, Sau­di Arabia’s Saudi Aramco, Norway’s Equinor, Brazil’s Petrobras, Malaysia’s Petronas, and Algeria’s Sonatrach. These NOCs can serve as sources of inspiration for NNPC. These five NOCs have also undergone …

Mining And The Sdgs: A 2020 Status Update, Responsible Mining Foundation, Columbia Center On Sustainable Investment

Columbia Center on Sustainable Investment Staff Publications

In September 2015, the UN member states agreed on a set of 17 Sustainable Development Goals (SDGs), which represent the global agenda for equitable, socially inclusive, and environmentally sustainable economic development until 2030. Mining companies have the potential to become leading partners in achieving the SDGs. Through their direct operations, mining companies can generate profits, employment, and economic growth in low-income countries. And through partnerships with government and civil society, mining companies can ensure that benefits of mining extend beyond the life of the mine itself, so that the mining industry has a positive impact on the natural environment, climate …

Class Actions And Private Antitrust Litigation, Albert H. Choi, Kathryn E. Sprier

Law & Economics Working Papers

When firms collude and charge supra-competitive prices, consumers can bring antitrust lawsuits against the firms. When the litigation cost is low, firms accept the cost as just another cost of doing business, whereas when the cost is high, the firms lower the price to deter litigation. Class action is modeled as a mechanism that allows plaintiffs and attorneys to obtain economies of scale. We show that class actions, and the firms' incentive to block them, may or may not be socially desirable. Agency problems, settlement, fee-shifting, treble damages, public enforcement, and sustaining collusion through repeat play are also considered.

Federal Forum Provisions And The Internal Affairs Doctrine, Dhruv Aggarwal, Albert H. Choi

Law & Economics Working Papers

A key question at the intersection of state and federal law is whether corporations can use their charters or bylaws to restrict securities litigation to federal court. In December 2018, the Delaware Chancery Court answered this question in the negative in the landmark decision Sciabacucchi v. Salzberg. The court invalidated “federal forum provisions” (“FFPs”) that allow companies to select federal district courts as the exclusive venue for claims brought under the Securities Act of 1933 (“1933 Act”). The decision held that the internal affairs doctrine, which is the bedrock of U.S. corporate law, does not permit charter and bylaw provisions …
