Digital Nudges: Contours And Challenges, Avishalom Tor

Book Chapters

Digital nudges—that is, significantly behavioral interventions that use software and its user-interface design elements—are an increasingly pervasive feature of online environments that shapes behavior both online (e.g., changing online privacy settings) and offline (e.g., taking a flu vaccine due to a text message reminder). Although digital nudges share many characteristics of their offline counterparts, they merit particular attention and analysis for two important reasons: First, the growing ubiquity of digital nudges makes encountering them nearly unavoidable in daily life, thereby bringing into sharper relief the promise and perils of nudges more generally. Second, the potentially greater potency of digital—compared to …

Nudge Efficiency, Avishalom Tor

Book Chapters

Only a small portion of the substantial literature on behavioral interventions ("nudges") that developed over the last fifteen to twenty years has considered nudges from an economic perspective. Moreover, despite the importance of the topic for a law and economics assessment of this increasingly common form of regulation, even fewer contributions have examined whether and when behavioral instruments are likely to make an efficient means for increasing social welfare. This chapter therefore offers some basic observations about nudge efficiency: Part I opens with a reminder that behavioral instruments should be implemented only when they are the most efficient means available …

Allocating State Authority Over Charitable Nonprofit Organizations, Lloyd H. Mayer

Journal Articles

This Essay considers the allocation of state authority to enforce the legal obligations particular to charities and their leaders among state officials, including attorneys general, judges, and legislators, and private parties. It first describes the existing allocation. It then reviews the most common criticisms of this allocation, which primarily focus on two concerns: politicization and lack of sufficient enforcement. Finally, it evaluates the most notable proposals for reallocating this authority, including the reallocation of this authority in part to private parties.

This Essay concludes that reform proposals have two fundamental flaws. First, proposals aimed at countering the political nature of …

If You Can't Beat Them, Join Them: Richard Posner And Behavioral Law And Economics, Avishalom Tor, Doran Teichman, Eyal Zamir

Journal Articles

Since its publication in 1973, Economic Analysis of Law (the Treatise) by Richard Posner has been recognized as the canonical treatise in the field. Given this status, observing changes over time in the different editions of the book can highlight substantial and methodological shifts in the area. On this backdrop, this brief essay will highlight Posner's change of attitude towards behavioral analysis of law over the years, culminating with the incorporation of behavioral insights into the las edition of this book, published in 2024.

The Private Costs Of Behavioral Interventions, Avishalom Tor

Journal Articles

The increasing popularity of behavioral interventions—also known as nudges—is largely due to their perceived potential to promote public and private welfare at dramatically lower costs than those of traditional regulatory instruments, such as mandates or taxes. Yet, though nudges typically involve low implementation costs, scholars and policymakers alike tend to underestimate their often-substantial private costs. Once these costs are accounted for, most nudges turn out to generate significantly lower net benefits than assumed, and some prove less efficient or less cost-effective than traditional instruments. At other times, the private costs of behavioral interventions are sufficiently large to render them socially …

When Should Governments Invest More In Nudging? Revisiting Benartzi Et Al. (2017), Avishalom Tor, Jonathan Klick

Journal Articles

Highly influential recent work by Benartzi et al. (2017) argues—using comparisons of effectiveness and costs—that behavioral interventions (or nudges) offer more cost-effective means than traditional regulatory instruments for changing individual behavior to achieve desirable policy goals. Based on this finding, these authors further conclude that governments and other organizations should increase their investments in nudging to supplement traditional interventions. Yet a closer look at Benartzi et al.’s (2017) own data and analysis reveals that they variously exclude and include key cost elements to the benefit of behavioral instruments over traditional ones and overstate the utility of cost-effectiveness analysis for policy …

The Law And Economics Of Behavioral Regulation, Avishalom Tor

Journal Articles

This article examines the law and economics of behavioral regulation (“nudging”), which governments and organizations increasingly use to substitute for and complement traditional instruments. To advance its welfare-based assessment, Section 1 examines alternative nudging definitions and Section 2 considers competing nudges taxonomies. Section 3 describes the benefits of nudges and their regulatory appeal, while Section 4 considers their myriad costs—most notably the private costs they generate for their targets and other market participants. Section 5 then illustrates the assessment of public and private welfare nudges using cost-benefit analysis, cost-effectiveness analysis, and rationality-effects analysis.

An Economic Approach To Religious Exemptions, Stephanie H. Barclay

Journal Articles

Externalities caused by religious exemptions have been getting the spotlight again in light a case the U.S. Supreme Court will hear this term: Fulton v. City of Philadelphia. Some argue that religious individuals should be required to internalize the costs they impose on third parties and thus should be denied the right to practice that harmful behavior. These new progressive theories about harm trade on rhetoric and normative intuitions regarding externalities and costs. But curiously, these theories also largely ignore an influential theoretical movement that has studied externalities and costs for the last fifty years: law and economics.

Nudges That Should Fail?, Avishalom Tor

Journal Articles

Professor Sunstein (2017) discusses possible causes for and policy implications of the failure of nudges, with a special attention to defaults. Though he focuses on nudges that fail when they should succeed, Sunstein recognizes that some failures reveal that a nudge should not have been attempted to begin with. Nudges that fail, however, does not consider fully the relationship between the outcomes of nudging and their likely welfare effects, most notably neglecting the troubling case of nudges that succeed when they should fail. Hence, after clarifying the boundaries of legitimate nudging and noting the fourfold relationship between the efficacy of …

The Diminishing Duty Of Loyalty, Julian Velasco

Journal Articles

Fiduciary duties comprise an integral part of corporate law. It is generally understood that directors owe the corporation and its shareholders two fiduciary duties: the duty of care and the duty of loyalty. Although both duties are firmly established in corporate law, they are not treated equally. It is generally understood that the duty of loyalty is enforced far more rigorously than the duty of care. The justification for this dichotomy is twofold. First, differential treatment is appropriate because of the relative urgencies of the underlying subject matter: loyalty issues pose greater risks than do care issues. Second, the deference …

Teaching The Lochner Era, Barry Cushman

Journal Articles

This article, prepared for the St. Louis University Law Journal's issue on “Teaching the Fourteenth Amendment,” develops a taxonomy of the Supreme Court's economic substantive due process jurisprudence during the so-called “Lochner Era” of the late-19th and early-20th centuries, and offers an assessment of the trajectory and mechanisms of the decline of that body of doctrine.

Remedies, Meet Economics; Economics, Meet Remedies, Samuel L. Bray

Journal Articles

One would expect the fields of ‘law and economics’ and ‘remedies’ to have substantial interaction, but scholars in each field largely ignore those in the other. Thus, law and economics scholars blunder in their description of the law of remedies, and remedies scholars are cut off from economic insights. For scholars who are in these fields, this article offers a critique, as well as suggestions for cooperation. For all legal scholars interested in melding conceptual and economic analysis, it offers a cautionary tale of disciplinary fragmentation.

The Market, The Firm, And Behavioral Antitrust, Avishalom Tor

Book Chapters

This Handbook chapter examines the main distinct concerns facing the application of empirical behavioral evidence to antitrust law and economics—also known as “behavioral antitrust.” More than many (though not all) other legal fields, antitrust law is primarily concerned with the conduct of firms in markets rather than in individual behavior per se. Yet much of the empirical evidence that behavioral antitrust draws on concerns individual behavior outside the firm, often in nonmarket settings. Hence besides adducing additional, direct empirical evidence on behavioral phenomena within firms and markets, there is a need to determine when and how the behavioral evidence on …

Some Challenges Facing A Behaviorally-Informed Approach To The Directive On Unfair Commercial Practices, Avishalom Tor

Book Chapters

The Directive on Unfair Commercial Practices seeks to protect consumers by prohibiting, inter alia, misleading practices, which are defined as practices that are likely to mislead the average consumer and thereby likely to cause him to take a transactional decision he would not have taken otherwise (Directive 2005/29/ EC of the European Parliament and of the Council). While determinations of what constitutes average consumer behavior, what misleads consumers, or how consumers make transactional decisions all can be made as a matter of law, based on anecdotal observations, intuitions or theoretical assumptions, an empirical behavioral foundation can put consumer law on …

A Consumer Decision-Making Theory Of Trademark Law, Mark Mckenna

Journal Articles

The consumer search costs theory has dominated discussion of trademark law for the last several decades. According to this theory, trademark law aims to increase consumer welfare by reducing the cost of shopping for goods or services, and it accomplishes this goal by preventing uses of a trademark that might confuse consumers about the source of the goods with which the mark is used. This conceptual frame is wrong, and it is complicit in most of trademark law’s extraordinary expansion. “Search costs” is not sufficiently precise; many types of search costs are irrelevant to consumer behavior, and even when search …

The Federal Reserve As Last Resort, Colleen Baker

Journal Articles

The Federal Reserve, the central bank of the United States, is one of the most important and powerful institutions in the world. Surprisingly, legal scholarship hardly pays any attention to the Federal Reserve or to the law structuring and governing its legal authority. This is especially curious given the amount of legal scholarship focused on administrative agencies that do not have anywhere near as critical a domestic and international role as that of the Federal Reserve. At the core of what the Federal Reserve does and should do is to conduct monetary policy so as to safeguard pricing, including that …

Toward Economic Analysis Of The Uniform Probate Code, Daniel B. Kelly

Journal Articles

Insights from economics and the economic analysis of law may be useful in analyzing succession law, including intestacy and wills as well as nonprobate transfers such as trusts. After surveying prior works that have examined succession from a functional perspective, I explore the possibility of utilizing tools like (i) transaction costs, (ii) the ex ante/ex post distinction, and (iii) rules versus standards, to illuminate the design of the Uniform Probate Code. Specifically, I investigate how these tools, which legal scholars have employed widely in other contexts, may be relevant in understanding events like the nonprobate revolution and issues like “dead …

Charting A Course In Clearing, Colleen M. Baker

Journal Articles

Memorable tales of financial collapse, such as that of Lehman Brothers (Lehman), Bear Stearns, and American Financial Group (AIG), frequently drive narratives of financial market crises and future preventative regulatory solutions. Much U.S. financial regulation, such as the monumental and historic “Dodd-Frank Wall Street Reform and Consumer Protection Act,” (Dodd-Frank) can be understood from this perspective. Aspects of such responses, however, are sometimes puzzling. An example is the reforms surrounding certain financial market utilities in Dodd-Frank’s Title VIII, “Payment, Clearing, and Settlement Supervision Act of 2010” (Title VIII). Financial market utilities often play a vital role in a process known …

Foreign Citizens In Transnational Class Actions, Jay Tidmarsh, Linda Sandstrom Simard

Journal Articles

This Article addresses an increasingly important question: When, if ever, should foreign citizens be included as members of an American class action? The existing consensus holds that courts should exclude from class membership those foreign citizens whose country does not recognize an American class judgment. Our analysis begins by establishing that this consensus is flawed. Rather, to minimize the costs associated with relitigation in a foreign forum, we must distinguish between foreign claimants who are likely to commence a subsequent foreign proceeding from those who are unlikely to do so; distinguishing between those who come from recognizing and nonrecognizing countries …

Optimal Class Size, Opt-Out Rights, And "Indivisible" Remedies, Jay Tidmarsh, David Betson

Journal Articles

Prepared for a Symposium on the ALI’s Aggregate Litigation Project, this paper examines the ALI’s proposal to permit opt-out rights when remedies and “divisible,” but not to permit them when remedies are “indivisible.” Starting from the ground up, the paper employs economic analysis to determine what the optimal size of a class action should be. We demonstrate that, in some circumstances, the optimal size of a class is a class composed of all victims, while in other cases, the optimal size is smaller. We further argue that courts should consider optimal class size in determining whether to certify a class, …

Foreword: Advances In The Behavioral Analysis Of Law: Markets, Institutions, And Contracts, Avishalom Tor

Journal Articles

Avishalom Tor, Special Editor

The collection of articles in this Special Issue is based on an international conference on Advances in the Behavioral Analysis of Law: Markets, Institutions, and Contracts that took place on December 8, 2009 at the University of Haifa Faculty of Law in Israel. The conference addressed cutting-edge legal issues at the intersection of law, economics, and psychology from a diverse set of viewpoints, bringing together scholars engaged in both theoretical and experimental behavioral analyses of law.

Behavioral Antitrust: A New Approach To The Rule Of Reason After Leegin, William J. Rinner, Avishalom Tor

Journal Articles

The Supreme Court’s recent decision in Leegin Creative Leather Products, Inc. v. PSKS, Inc., which replaced the longstanding per-se rule against resale price maintenance (RPM) with a rule of reason approach, has resurrected the debate over RPM. Legal and economic proponents of this practice again point to its potential procompetitive benefits, while RPM detractors emphasize its possible anticompetitive consequences. Despite their disagreements regarding the overall RPM evaluation, however, scholars, the Court, and the limited empirical data appear near-unanimous in agreeing that such arrangements can either increase or decrease efficiency. Consequently, the RPM debate predominantly revolves around theoretical assertions regarding the …

The Methodology Of The Behavioral Analysis Of Law, Avishalom Tor

Journal Articles

This article examines the behavioral analysis of law, meaning the application of empirical behavioral evidence to legal analysis, which has become increasingly popular in legal scholarship in recent years. Following the introduction in Part I, this Article highlights four central propositions on the subject. The first, developed in Part II, asserts that the efficacy of the law often depends on its accounting for relevant patterns of human behavior, most notably those studied by behavioral decision scientists. This Part therefore reviews important behavioral findings, illustrating their application and relevance to a broad range of legal questions. Part III then argues that …

Comment: On Contractual Defaults And Experimental Law And Economics, Avishalom Tor

Journal Articles

It is possible that contract default rules, whose relevance is contingent upon parties' agreement to contract, differ from other default states. Parties therefore might not perceive contingent contractual defaults as relevant reference points. Ironically, however, Sloof, Oosterbeek and Sonnemans' (SOS) "default contract" applied inevitably whenever proposed and whenever Respondents rejected a non-default proposal, bearing greater resemblance to a legal right than to a contractual default. Thus, the contingency of typical contractual defaults cannot account for the No Bias Finding. Other aspects of the SOS experimental design, on the other hand, may explain the No Bias Finding.

Pilgrim Law: Overcoming False Consciousness Through The Witness Of London's Economic Migrants, Vincent D. Rougeau

Journal Articles

The article discusses the author's view on the works and beliefs of Robert E. Rodes Jr. He considered faith and professional life as the powerful link on Rodes works and cited three points of reflection on the matter which includes on Rodes' concept of "Pilgrim Law" that has been influential on the author's works, thinking about the relationship between the professional roles of a lawyer and a call to a lived Christian faith. He believed that the Rodes' book "Pilgrim Law" took a formidable task on extending the principles of the theology of liberation to American jurisprudence and became an …

Rankings, Standards, And Competition: Task Vs. Scale Comparisions, Avishalom Tor, Stephen M. Garcia

Journal Articles

Research showing how upward social comparison breeds competitive behavior has so far conflated local comparisons in task performance (e.g. a test score) with comparisons on a more general scale (i.e. an underlying skill). Using a ranking methodology (Garcia, Tor, & Gonzalez, 2006) to separate task and scale comparisons, Studies 1–2 reveal that an upward comparison on the scale (e.g. being surpassed in rank), rather than in the mere task (e.g., being outperformed), is necessary to generate competition among rivals proximate to a standard (e.g. ranked #3 vs. 4, near “the top”); rivals far from a standard (e.g. ranked …

"We Shall Not Be Moved": Urban Communities, Eminent Domain And The Socioeconomics Of Just Compensation, James J. Kelly

Journal Articles

If eminent domain is to serve true community development, statutory reforms must limit its propensity to abuse while still preserving its effectiveness. The first part of this article offers a normative legal theory of eminent domain as constrained by both the availability of alternative means of achieving public objectives and the inability of some condemnees to be made whole by cash compensation. The consideration of the land needs of both the condemnor and the condemnee is crucial to the respective evaluations of public use and just compensation as limitations on eminent domain. In the context of urban redevelopment, the theory …

Penalty Defaults In Family Law: The Case Of Child Custody, Margaret F. Brinig

Journal Articles

This paper considers whether an amendment to state divorce laws that strengthens its joint custody preference operates as a traditional default rule, specifying what most divorcing couples would choose or as a penalty default rule the parties will attempt to contract around.

While the Oregon statutes that frame our discussion here, like most state laws, do not state an explicit preference for joint custody, shared custody is certainly encouraged by Section 107.179, which refers cases in which the parties cannot agree on joint custody to mediation and by Section 107.105, which requires the court to consider awarding custody jointly. In …

The Neglected Political Economy Of Eminent Domain, Nicole Stelle Garnett

Journal Articles

This Article challenges a foundational assumption about eminent domain - namely, that owners are systematically undercompensated because they receive only fair market value for their property. The Article shows that, in fact, scholars have overstated the undercompensation problem because they have focused on the compensation required by the Constitution, rather than on the actual mechanics of eminent domain. The Article examines three ways that Takers (i.e., non-judicial actors in the eminent domain process) minimize undercompensation. First, Takers may avoid taking high-subjective-value properties. Second, Takers frequently must pay more compensation in the form of relocation assistance. Third, Takers and property owners …
