Reconceptualizing Trespass, Gideon Parchomovsky, Alex Stein

All Faculty Scholarship

This Essay addresses an anomaly in trespass law. Trespass law is generally understood as the paradigmatic example of property-rule protection: an owner can obtain an injunction against the trespasser and have him removed from her land. The property-rule protection enjoyed by the owner protects her right to exclude others and to set the price for the use of her property. However, the property-rule protection only exists ex ante: it avails only against imminent or ongoing trespasses. Ex post, after a trespass ends, the owner can only recover compensation measured by the market value of the unauthorized use, i.e., the going …

Social Facts, Constitutional Interpretation, And The Rule Of Recognition, Matthew D. Adler

All Faculty Scholarship

This essay is a chapter in a volume that examines constitutional law in the United States through the lens of H.L.A. Hart’s “rule of recognition” model of a legal system. My chapter focuses on a feature of constitutional practice that has been rarely examined: how jurists and scholars argue about interpretive methods. Although a vast body of scholarship provides arguments for or against various interpretive methods --such as textualism, originalism, “living constitutionalism,” structure-and-relationship reasoning, representation-reinforcement, minimalism, and so forth -- very little scholarship shifts to the meta-level and asks: What are the considerations that jurists and scholars bring to bear …

The Effect Of Economics And Electronic Resources On The Traditional Law Library Print Collection, Amanda M. Runyon

Librarian Scholarship at Penn Law

The exponential rise in the cost of legal materials and the increasing availability of and expectation for electronic materials have strained the budgets of academic law libraries. The author surveyed directors of academic law libraries to identify trends in collection management, such as canceling, weeding, and signing library maintenance agreements.

Problems Of Equity And Efficiency In The Design Of International Greenhouse Gas Cap-And-Trade Schemes, Jason S. Johnston

All Faculty Scholarship

This article argues that international greenhouse gas (GHG) cap-and-trade schemes suffer from inherent problems of enforceability and verifiability that both cause significant inefficiencies and create inevitable tradeoffs between equity and efficiency. A standard result in the economic analysis of international GHG cap and trade schemes is that an allocation of initial permits that favors poor, developing countries (making such countries net sellers in equilibrium) may be necessary not only to further redistributive goals but also the efficiency of the GHG cap and trade scheme. This coincidence of equity and efficiency is, however, unlikely to be realized under more realistic assumptions …

Immigration Restriction As Redistributive Taxation: Working Women And The Costs Of Protectionism In The Labor Market, Howard F. Chang

All Faculty Scholarship

In this paper, I argue that tax and transfer policies are more efficient than immigration restrictions as instruments for raising the after-tax incomes of the least skilled native workers. Policies to protect these native workers from immigrant competition in the labor market do no better at promoting distributive justice and are likely to impose a greater economic burden on natives in the country of immigration than the tax alternative. These immigration restrictions are especially costly given the disproportionate burden that they place on households with working women, which discourages female participation in the labor force. This burden runs contrary to …

Hedge Fund Activism In The Enforcement Of Bondholder Rights, Marcel Kahan, Edward B. Rock

All Faculty Scholarship

Activist hedge funds have transformed how bondholders respond to violations of their contractual rights. Insurance companies and mutual funds, the traditional investors in bonds, often slept on their rights and turned active only little and late. Hedge funds, by contrast, seek out opportunities for activism in order to make profits. In the wake of their activism, hedge funds have not only benefitted themselves, but their fellow bondholders as well. Alas, the remedy scheme for violations of bondholders rights – in particular, the centrality of the acceleration remedy – introduces its own set of imperfections. When treasury interest rates have increased …

Wikitruth Through Wikiorder, David A. Hoffman, Salil K. Mehra

All Faculty Scholarship

How does large-scale social production coordinate individual behavior to produce public goods? Hardin (1968) denied that the creation of public goods absent markets or the State is possible. Benkler (2006), Shirky (2008), Zittrain (2008), and Lessig (2008) recently countered that the needed coordination might emerge though social norms. However, the means to this coordination is under-theorized. Focusing on Wikipedia, we argue that the site’s dispute resolution process is an important force in promoting the public good it produces, i.e., a large number of relatively accurate public encyclopedia articles. We describe the development and shape of Wikipedia’s existing dispute resolution system. …

The Effects Of Tort Reform On Medical Malpractice Insurers’ Ultimate Losses, Patricia Born, W. Kip Viscusi, Tom Baker

All Faculty Scholarship

Whereas the literature evaluating the effect of tort reforms has focused on reported incurred losses, this paper examines the long run effects using a comprehensive sample by state of individual firms writing medical malpractice insurance from 1984-2003. The long run effects of reforms are greater than insurers' expected effects, as five year developed losses and ten year developed losses are below the initially reported incurred losses for those years following reform measures. The quantile regressions show the greatest effects of joint and several liability limits, noneconomic damages caps, and punitive damages reforms for the firms that are at the high …

Whose Eyes Are You Going To Believe? Scott V. Harris And The Perils Of Cognitive Illiberalism, Dan M. Kahan, David A. Hoffman, Donald Braman

All Faculty Scholarship

This paper accepts the unusual invitation to see for yourself issued by the Supreme Court in Scott v. Harris, 127 S. Ct. 1769 (2007). Scott held that a police officer did not violate the Fourth Amendment when he deliberately rammed his car into that of a fleeing motorist who refused to pull over for speeding and instead attempted to evade the police in a high-speed chase. The majority did not attempt to rebut the arguments of the single Justice who disagreed with its conclusion that no reasonable juror could find the fleeing driver did not pose a deadly risk …

Cause For Concern: Causation And Federal Securities Fraud, Jill E. Fisch

All Faculty Scholarship

The Supreme Court’s decision in Dura Pharmaceuticals dramatically changed federal securities fraud litigation. The Dura decision itself said little, but counseled lower courts to fashion new requirements of causation and harm modeled upon common law tort principles. These instructions have led lower courts to craft a series of confusing and inconsistent decisions that incorporate little of the reasoning upon which the common law principles are based. This Article accepts the Dura challenge and examines both common law causation principles and their applicability to federal securities fraud. In so doing, the Article identifies the failure of the federal courts properly to …

Complex Bundled Discounts And Antitrust Policy, Herbert J. Hovenkamp, Erik Hovenkamp

All Faculty Scholarship

A bundled discount occurs when a seller conditions a discount or rebate on the buyer's purchaser or two or more different products. Firms that produce fewer than all the good in the bundle find it difficult to compete because they must amortize the discount across a smaller range of goods. For example, if the dominant firm offers a 10% discount for purchase of both good A and good B, but the rival makes only good B, it will have to offer a discount that is large enough to match the dominant firm's B discount as well as the foregone discount …

A Right To Bear Firearms But Not To Use Them? Defensive Force Rules And The Increasing Effectiveness Of Non-Lethal Weapons, Paul H. Robinson

All Faculty Scholarship

Under existing American law, advances in non-lethal weapons increasingly make the use of firearms for defense unlawful and the Second Amendment of little practical significance. As the effectiveness and availability of less lethal weapons increase, the choice of a lethal firearm for protection is a choice to use more force than is necessary, in violation of existing self-defense law. At the same time, a shift to non-lethal weapons increases the frequency of situations in which a person’s use of force is authorized because defenders with non-lethal weapons are freed from the special proportionality requirements that limit the use of deadly …

Constitutional Theory And The Rule Of Recognition: Toward A Fourth Theory Of Law, Mitchell N. Berman

All Faculty Scholarship

This essay, a contribution to a forthcoming edited volume on Hart's rule of recognition and the U.S. Constitution, advances one argument and pitches one proposal. The argument is that Hart's theory of law does not succeed. On Hart's account, legal propositions are what they are - that is, they have the particular content and status that they do - by virtue of their satisfying necessary and sufficient conditions that are themselves established by a special sort of convergent practice among officials. American constitutional theorists are often troubled by this account because it seems to imply that in the "hard cases" …

Liability Insurance At The Tort-Crime Boundary, Tom Baker

All Faculty Scholarship

This essay explores how liability insurance mediates the boundary between torts and crime. Liability insurance sometimes separates these two legal fields, for example through the application of standard insurance contract provisions that exclude insurance coverage for some crimes that are also torts. Perhaps less obviously, liability insurance also can draw parts of the tort and criminal fields together. For example, professional liability insurance civilizes the criminal law experience for some crimes that are also torts by providing defendants with an insurance-paid criminal defense that provides more than ordinary means to contest the state’s accusations. The crime-tort separation in liability insurance …

Stereotype Threat: A Case Of Overclaim Syndrome?, Amy L. Wax

All Faculty Scholarship

The theory of Stereotype Threat (ST) predicts that, when widely accepted stereotypes allege a group’s intellectual inferiority, fears of confirming these stereotypes cause individuals in the group to underperform relative to their true ability and knowledge. There are now hundreds of published studies purporting to document an impact for ST on the performance of women and racial minorities in a range of situations. This article reviews the literature on stereotype threat, focusing especially on studies investigating the influence of ST in the context of gender. It concludes that there is currently no justification for concluding that ST explains women’s underperformance …

Neoclassicism And The Separation Of Ownership And Control, Herbert J. Hovenkamp

All Faculty Scholarship

"Separation of ownership and control" is a phrase whose history will forever be associated with Adolf A. Berle and Gardiner C. Means' The Modern Corporation and Private Property (1932), as well as with Institutionalist economics, Legal Realism, and the New Deal. Within that milieu the large publicly held business corporation became identified with excessive managerial power at the expense of stockholders, social irresponsibility, and internal inefficiency. Neoclassical economists both then and ever since have generally been critical, both of the historical facts that Berle and Means purported to describe and of the conclusions that they drew. In fact, however, within …

Patents, Property, And Competition Policy, Herbert J. Hovenkamp

All Faculty Scholarship

The decision to regulate involves the identification of markets where simple assignment of property rights is not sufficient to ensure satisfactory competitive results, usually because some type of market failure obtains. By contrast, if property rights are well defined when they are initially created and can subsequently be traded to some reasonably competitive equilibrium, then regulation is thought not to be necessary. In such cases the antitrust laws have a significant role to play in ensuring that the market can be as competitive as free trading allows. One problem with the patent system is that once a patent is granted …

Strong Claims And Weak Evidence: Reassessing The Predictive Validity Of The Iat, Hart Blanton, James Jaccard, Jonathan Klick, Barbara Mellers, Gregory Mitchell, Philip Tetlock

All Faculty Scholarship

The authors reanalyzed data from 2 influential studies — A. R. McConnell and J. M. Leibold (2001) and J. C. Ziegert and P. J. Hanges (2005) — that explore links between implicit bias and discriminatory behavior and that have been invoked to support strong claims about the predictive validity of the Implicit Association Test. In both of these studies, the inclusion of race Implicit Association Test scores in regression models reduced prediction errors by only tiny amounts, and Implicit Association Test scores did not permit prediction of individual-level behaviors. Furthermore, the results were not robust when the impact of rater …

United States Competition Policy In Crisis: 1890-1955, Herbert J. Hovenkamp

All Faculty Scholarship

The development of marginalist, or neoclassical, economics led to a fifty-year long crisis in competition theory. Given an industrial structure with sufficient fixed costs, competition always became "ruinous," forcing firms to cut prices to marginal cost without sufficient revenue remaining to pay off investment. Early neoclassicists such as Alfred Marshall were not able to solve this problem, and as a result many economists were hostile toward the antitrust laws in the early decades of the twentieth century. The ruinous competition debate came to an abrupt end in the early 1930's, when Joan Robinson and particularly Edward Chamberlin developed models that …

Medical Hope, Legal Pitfalls: Potential Legal Issues In The Emerging Field Of Oncofertility, Gregory Dolin, Dorothy E. Roberts, Lina M. Rodriguez, Teresa K. Woodruff

All Faculty Scholarship

The article will begin its discussion by identifying the values at stake in the field of oncofertility. These values include the constitutional protection of the rights of women and minors to bear children and to use reproduction-assisting technologies, as well as the feminist critique of gendered expectations that may pressure women to use these technologies.

Part III will focus on the medical options of oncofertility. It will also discuss some conditions that may lead otherwise fertile and young patients to lose their ability to bear children as a side-effect of necessary medical treatment. The article will then proceed to discuss …

Samuel Zell, The Chicago Tribune, And The Emergence Of The S Esop: Understanding The Tax Advantages And Disadvantages Of S Esops, Michael S. Knoll

All Faculty Scholarship

Samuel Zell’s acquisition of the Chicago Tribune Company (the Tribune) in December 2007 using a little-known type of Employee Stock Ownership Plan (ESOP) made headlines. In a complicated transaction, which took nearly a year to complete, the Tribune converted from a subchapter C corporation to a subchapter S corporation, established an ESOP that purchased 100 percent of the company’s equity, and sold Zell a call option giving him the right to purchase 40 percent of the company’s equity. Press reports claim that Zell’s novel structure enabled Zell to outbid other suitors. And financial commentators predict that many acquirers will employ …

Director Elections And The Role Of Proxy Advisors, Stephen Choi, Jill E. Fisch, Marcel Kahan

All Faculty Scholarship

Using a dataset of proxy recommendations and voting results for uncontested director elections from 2005 and 2006 at S&P 1500 companies, we examine how advisors make their recommendations. Of the four firms we study, Institutional Shareholder Services (ISS), Proxy Governance (PGI), Glass Lewis (GL), and Egan Jones (EJ), ISS has the largest market share and is widely regarded as the most influential. We find that the four proxy advisory firms differ substantially from each other both in their willingness to issue a withhold recommendation and in the factors that affect their recommendation. It is not clear that these differences, or …
