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.

Spillover Effects In Police Use Of Force, Justin E. Holz, Roman G. Rivera, Bocar A. Ba

All Faculty Scholarship

We study the link between officer injuries-on-duty and the force-use of their peers using a network of officers who, through a random lottery, began the police academy together. We find that peer injuries-on-duty increase the probability of using force by 7%. The effect is concentrated in a narrow time window near the event and is not associated with significantly lower injury risk to the officer. Complaints of improper searches and failure to provide service also increase after peer injuries, suggesting that the increase in force might be driven by heightened risk aversion.

In-Group Bias And The Police: Evidence From Award Nominations, Nayoung Rim, Roman G. Rivera, Bocar A. Ba

All Faculty Scholarship

This paper examines the impact of in-group bias on the internal dynamics of a police department. Prior studies have documented racial bias in policing, but little is known about bias against officers due to lack of available data. We construct a novel panel dataset of Chicago Police Department officers, with detailed information on officer characteristics and work productivity. Exploiting quasi-random variation in supervisor assignment, we find that white supervisors are less likely to nominate black officers than white or Hispanic officers. We find weaker evidence that male supervisors are less likely to nominate female officers than male officers. We explore …

The Inevitability And Ubiquity Of Cycling In All Feasible Legal Regimes: A Formal Proof, Leo Katz, Alvaro Sandroni

All Faculty Scholarship

Intransitive choices, or cycling, are generally held to be the mark of irrationality. When a set of rules engenders such choices, it is usually held to be irrational and in need of reform. In this article, we prove a series of theorems, demonstrating that all feasible legal regimes are going to be rife with cycling. Our first result, the legal cycling theorem, shows that unless a legal system meets some extremely restrictive conditions, it will lead to cycling. The discussion that follows, along with our second result, the combination theorem, shows exactly why these conditions are almost impossible to meet. …

Teoría Prospectiva, Efecto Marco Y Los Mensajes De Disuasión De Consumo De Tabaco En Colombia, Daniel Monroy

Daniel A Monroy C

The main target of this reflex paper is to explain some ideas about behavioral economics, such as the Prospect Theory and the framing effect, as well as its possible implications for the law, especially in the context of tobacco control law in Colombia and the current package warning labels. The paper concludes that these warnings have the potential to reduce the tobacco consumption. However the effectiveness of these messages could be increased if the information is reframed in an alternative way.

Más Vale Malo Conocido Que…: El Efecto Dotación Y Los Pronósticos Teóricos Del Teorema De Coase, Daniel Monroy

Daniel A Monroy C

Some studies of the "endowment effect" in behavioral economics have criticized the theoretical prediction of the Coase Theorem even in its most basic formulation. This document describes the evidence of the existence of this "anomaly" in individual decision-making in various contexts in order to determine the possible general implications of this effect in the economic analysis itself especially as an explanation for the sometimes, insuperable gap between the willingness to accept for giving a right and the correlative willingness to pay to get it, also the paper describes a contradiction with the assumption of reversibility of preferences at any dot …

How Much Does A Belief Cost?: Revisiting The Marketplace Of Ideas, Gregory Brazeal

Gregory Brazeal

Justice Oliver Wendell Holmes, Jr. is often credited with creating the metaphor of “the marketplace of ideas,” though he did not use the exact phrase and his argument for free speech was not based on distinctively economic reasoning. Truly economic investigations of the marketplace of ideas have progressed in step with developments and trends in the law and economics literature. These investigations have tended to be one-sided, with writers focusing primarily either on the production of ideas (for example, Posner) or their consumption (for example, behavioral law and economics), without considering in depth how producers and consumers interact. This may …

Mixed Signals: Rational-Choice Theories Of Social Norms And The Pragmatics Of Explanation, W. Bradley Wendel

Cornell Law Faculty Publications

The question of how societies secure cooperation and order in the absence of state enforced sanctions has long vexed law and economics scholars. Recently the concept of social norms--informally enforced rules of behavior--has occupied the attention of a large number of these theorists, who are concerned with understanding why economically rational actors would bother to follow rules whose costs seem to outweigh their benefits. Because of the prestige (or at least trendiness) of law and economics, it seems that now everyone in the legal academy is talking about social norms. This burgeoning scholarship is closely related to a wider concern …

Can Law And Economics Be Both Practical And Principled?, David A. Hoffman, Michael P. O'Shea

All Faculty Scholarship

This article describes important recent developments in normative law and economics, and the difficulties they create for the project of efficiency-based legal reform. After long proceeding without a well articulated moral justification for using economic decision procedures to choose legal rules, scholars have lately begun to devote serious attention to developing a philosophically attractive definition of well-being. At the same time, the empirical side of law and economics is also being enriched with an improved understanding of the complexities of individuals' decision-making behavior. That is where the problems begin. Scholars may have better, more plausible conceptions of well-being in hand, …

"Public Use" And The Independent Judiciary: Condemnation In An Interest-Group Perspective, Donald J. Kochan

Donald J. Kochan

This Article reexamines the doctrine of public use under the Takings Clause and its ability to impede takings for private use through an application of public choice theory. It argues that the judicial validation of interest-group capture of the condemnation power through a relaxed public use standard in Takings Clause review can be explained by interest group politics and public choice theory and by institutional tendencies inherent in the independent judiciary. Legislators can sell the eminent domain power to special interests for almost any use, promising durability in the deal given the low probability that the judiciary will invalidate it …
