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 …

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 …

Is Data Localization A Solution For Schrems Ii?, Anupam Chander

Georgetown Law Faculty Publications and Other Works

For the second time this decade, the Court of Justice of the European Union has struck a blow against the principal mechanisms for personal data transfer to the United States. In Data Protection Commissioner v Facebook Ireland, Maximillian Schrems, the Court declared the EU-US Privacy Shield invalid and placed significant hurdles to the process of transferring personal data from the European Union to the United States via the mechanism of Standard Contractual Clauses. Many have begun to suggest data localization as the solution to the problem of data transfer; that is, don’t transfer the data at all. I argue …

The 2010 Hmgs Ten Years Later: Where Do We Go From Here?, Steven C. Salop, Fiona Scott Morton

Georgetown Law Faculty Publications and Other Works

In this short article, which is part of a RIO Symposium on the Tenth Anniversary of the 2010 Merger Guidelines, we suggest a number of improvements that should be considered in the next revision of the Guidelines. Our analysis is based on the observation that horizontal merger policy has suffered from under-enforcement. We provide evidence that the enforcement agencies face significant resource constraints which require a triage process that inevitably leads to under-enforcement. In light of merger law placing greater weight on avoiding false negatives and under-deterrence than false positive and over-deterrence, the article suggests a number of ways in …

Reverse Bayesianism And Act Independence, Surajeet Chakravarty, David Kelsey, Joshua C. Teitelbaum

Georgetown Law Faculty Publications and Other Works

Karni and Vierø (2013) propose a model of belief revision under growing awareness—reverse Bayesianism—which posits that as a person becomes aware of new acts, consequences, or act-consequence links, she revises her beliefs over an expanded state space in a way that preserves the relative likelihoods of events in the original state space. A key feature of the model is that reverse Bayesianism does not fully determine the revised probability distribution. We provide an assumption—act independence—that imposes additional restrictions on reverse Bayesian belief revision. We show that with act independence knowledge of the probabilities of the new …

The Cost Of Legal Restrictions On Experience Rating, Levon Barseghyan, Francesca Molinari, Darcy Steeg Morris, Joshua C. Teitelbaum

Georgetown Law Faculty Publications and Other Works

We investigate the cost of legal restrictions on experience rating in auto and home insurance. The cost is an opportunity cost as experience rating can mitigate the problems associated with unobserved heterogeneity in claim risk, including mispriced coverage and resulting demand distortions. We assess this cost through a counterfactual analysis in which we explore how risk predictions, premiums, and demand in home insurance and two lines of auto insurance would respond to unrestricted multiline experience rating. Using claims data from a large sample of households, we first estimate the variance-covariance matrix of unobserved heterogeneity in claim risk. We then show …

Conclusion: A Way Forward, Peter B. Edelman

Georgetown Law Faculty Publications and Other Works

Where do we go next? I have three suggestions. One is to enlarge the frame of our work on poverty and race, including a focus on the ever-widening chasm of inequality, and all of it pressing toward the center stage of national attention. A second is to consolidate our work about income, jobs, and cash assistance into a unified frame, which I call a three-legged stool. And the third is to think from a perspective of place, and what that tells us about our antipoverty work.

We need a banner, a message, a theme, a politics for ending poverty. The …

Considering Law And Macroeconomics, Anna Gelpern, Adam J. Levitin

Georgetown Law Faculty Publications and Other Works

The worst financial and economic crisis to hit the world’s richest economies since the Great Depression inspired a flood of scholarship that straddled the disciplines of law and macroeconomics. With few exceptions, this crisis scholarship did not set out to build a new interdisciplinary movement and did not claim the legacy of earlier efforts to mine the intersection of law and macroeconomics. What are we to make of this moment ten years on? Could Law and Macroeconomics (#LawMacro for short) be an important new turn in legal and economic thought, a casual interdisciplinary tryst on the margins of a hundred-year …

Quantifying The Increase In “Effective Concentration” From Verticle Mergers That Raise Input Foreclosure Concerns: Comment On The Draft Vertical Merger Guidelines, Serge Moresi, Steven C. Salop

Georgetown Law Faculty Publications and Other Works

This comment responds to the request by the Federal Trade Commission and the Department of Justice’s Antitrust Division for public comment on the draft 2020 Vertical Merger Guidelines. In this comment, we show that there is an inherent loss of an indirect competitor and competition when a vertical merger raises input foreclosure concerns. We also show that it then is possible to calculate an effective increase in the HHI measure of concentration for the downstream market. We refer to this “proxy” measure as the “dHHI.” We derive the dHHI measure by comparing the pricing incentives and associated upward …

Recommendations And Comments On The Draft Vertical Merger Guidelines, Jonathan B. Baker, Nancy L. Rose, Steven C. Salop, Fiona Scott Morton

Georgetown Law Faculty Publications and Other Works

These recommendations and comments respond to the request by the Federal Trade Commission and the Department of Justice’s Antitrust Division for public comment on the draft 2020 Vertical Merger Guidelines. We commend the agencies for updating the 1984 non-horizontal merger guidelines by recognizing the substantial advances in economic thinking about vertical mergers in the thirty-five years since those guidelines were issued. Our comments emphasize four issues: (i) the treatment of the elimination of double marginalization (“EDM”), particularly that the draft vertical merger guidelines appear inappropriately to make proof of cognizability part of the agencies burden and that they appear to …

Why A Wealth Tax Is Definitely Constitutional, John R. Brooks, David Gamage

Georgetown Law Faculty Publications and Other Works

Wealth tax reform proposals are playing a major role in the 2020 presidential campaign. However, some opponents of these wealth tax reform proposals have claimed that a wealth tax would be unconstitutional. Other prominent critics have argued that wealth tax reforms are probably unconstitutional, so that, after review by the courts, the “likeliest outcome is that a wealth tax will raise exactly zero dollars.”

These claims are wrong. More precisely, these claims are wrong conditioned on wealth tax legislation being carefully drafted so as to ensure its constitutionality. As we will explain in this essay, properly drafted, wealth tax reform …

The Costs And Benefits Of Affordable Housing: A Partial Solution To The Conflict Of Competing Goods, Michael R. Diamond

Georgetown Law Faculty Publications and Other Works

In this Article, I extend a prior inquiry into the costs borne by society due to the lack of enough decent, affordable housing units. I previously outlined those costs and suggested a combination of public cost savings and public and private benefits that would accrue by providing that housing. I posited that the savings and benefits, in the aggregate, could at least substantially offset the costs and might even exceed them. If that is so, I queried, why has society not produced the needed units? In answering that question, I offered several possible responses: inadequate resources, racism, and public choice …
