Police Frisks, David S. Abrams, Hanming Fang, Priyanka Goonetilleke

All Faculty Scholarship

The standard economic model of police stops implies that the contraband hit rate should rise when the number of stops falls, ceteris paribus. We provide empirical corroboration of such optimizing models of police behavior by examining changes in stops and frisks around two extraordinary events of 2020 - the pandemic onset and the nationwide protests following the killing of George Floyd. We find that hit rates from pedestrian and vehicle stops generally rose as stops and frisks fell dramatically. Using detailed data, we are able to rule out a number of alternative explanations, including changes in street population, crime, police …

The Deregulation Deception, Cary Coglianese, Natasha Sarin, Stuart Shapiro

All Faculty Scholarship

President Donald Trump and members of his Administration repeatedly asserted that they had delivered substantial deregulation that fueled positive trends in the U.S. economy prior to the COVID pandemic. Drawing on an original analysis of data on federal regulation from across the Trump Administration’s four years, we show that the Trump Administration actually accomplished much less by way of deregulation than it repeatedly claimed—and much less than many commentators and scholars have believed. In addition, and also contrary to the Administration’s claims, overall economic trends in the pre-pandemic Trump years tended simply to follow economic trends that began years earlier. …

Enhanced Public Defense Improves Pretrial Outcomes And Reduces Racial Disparities, Paul S. Heaton

All Faculty Scholarship

Numerous jurisdictions are working to reform pretrial processes to reduce or eliminate money bail and decrease pretrial detention. Although reforms such as the abandonment of bail schedules or adoption of actuarial risk assessment tools have been widely enacted, the role of defense counsel in the pretrial process has received less attention.

This Article considers an approach to pretrial reform focused on improving the quality of defense counsel. In Philadelphia, a substantial fraction of people facing criminal charges are detained following rapid preliminary hearings where initial release conditions are set by bail magistrates operating with limited information. Beginning in 2017, the …

Unrules, Cary Coglianese, Gabriel Scheffler, Daniel Walters

All Faculty Scholarship

At the center of contemporary debates over public law lies administrative agencies’ discretion to impose rules. Yet, for every one of these rules, there are also unrules nearby. Often overlooked and sometimes barely visible, unrules are the decisions that regulators make to lift or limit the scope of a regulatory obligation, for instance through waivers, exemptions, and exceptions. In some cases, unrules enable regulators to reduce burdens on regulated entities or to conserve valuable government resources in ways that make law more efficient. However, too much discretion to create unrules can facilitate undue business influence over the law, weaken regulatory …

Misdemeanors By The Numbers, Sandra G. Mayson, Megan T. Stevenson

All Faculty Scholarship

Recent scholarship has underlined the importance of criminal misdemeanor law enforcement, including the impact of public-order policing on communities of color, the collateral consequences of misdemeanor arrest or conviction, and the use of misdemeanor prosecution to raise municipal revenue. But despite the fact that misdemeanors represent more than three-quarters of all criminal cases filed annually in the United States, our knowledge of misdemeanor case processing is based mostly on anecdote and extremely localized research. This Article represents the most substantial empirical analysis of misdemeanor case processing to date. Using multiple court-record datasets, covering several million cases across eight diverse jurisdictions, …

Boots And Bail On The Ground: Assessing The Implementation Of Misdemeanor Bail Reforms In Georgia, Andrea Woods, Sandra G. Mayson, Lauren Sudeall, Guthrie Armstrong, Anthony Potts

All Faculty Scholarship

This Article presents a mixed-methods study of misdemeanor bail practice across Georgia in the wake of reform. We observed bail hearings and interviewed system actors in a representative sample of fifty-five counties to assess the extent to which pretrial practice conforms to legal standards clarified in Senate Bill 407 and Walker v. Calhoun. We also analyzed jail population data published by county jails and by the Georgia Department of Community Affairs. We found that a handful of counties have made promising headway in adhering to law and best practices, but that the majority have some distance to go. Most …

The Global Diffusion Of Law: Transnational Crime And The Case Of Human Trafficking, Beth A. Simmons, Paulette Lloyd, Brandon M. Steward

All Faculty Scholarship

The past few decades have seen the proliferation of new laws criminalizing certain transnational activities, from money laundering to corruption; from insider trading to trafficking in weapons and drugs. Human trafficking is one example. We argue criminalization of trafficking in persons has diffused in large part because of the way the issue has been framed: primarily as a problem of organized crime rather than predominantly an egregious human rights abuse. Framing human trafficking as an organized crime practice empowers states to confront cross border human movements viewed as potentially threatening. We show that the diffusion of criminalization is explained by …

The Scale Of Misdemeanor Justice, Megan T. Stevenson, Sandra G. Mayson

All Faculty Scholarship

This Article seeks to provide the most comprehensive national-level empirical analysis of misdemeanor criminal justice that is currently feasible given the state of data collection in the United States. First, we estimate that there are 13.2 million misdemeanor cases filed in the United States each year. Second, contrary to conventional wisdom, this number is not rising. Both the number of misdemeanor arrests and cases filed have declined markedly in recent years. In fact, national arrest rates for almost every misdemeanor offense category have been declining for at least two decades, and the misdemeanor arrest rate was lower in 2014 than …

Assessing The International Criminal Court, Beth A. Simmons, Mitchell Radtke, Hyeran Jo

All Faculty Scholarship

One of the most important issues surrounding international courts is whether they can further the dual causes of peace and justice. None has been more ambitious in this regard than the International Criminal Court (ICC). And yet the ICC has been the object of a good deal of criticism. Some people claim it has been an expensive use of resources that might have been directed to other purposes. Others claim that its accomplishments are meager because it has managed to try and convict so few people. And many commentators and researchers claim that the Court faces an inherent tension between …

Actions Speak Louder Than Images: The Use Of Neuroscientific Evidence In Criminal Cases, Stephen J. Morse

All Faculty Scholarship

This invited commentary for Journal of Law & the Biosciences considers four empirical studies previously published in the journal of the reception of neuroscientific evidence in criminal cases in the United States, Canada, England and Wales, and the Netherlands. There are conceded methodological problems with all, but the data are nonetheless instructive and suggestive. The thesis of the comment is that the courts are committing the same errors that have bedeviled the reception of psychiatric and psychological evidence. There is insufficient caution about the state of the science, and more importantly, there is insufficient understanding of the relevance of the …

Identifying Criminals’ Risk Preferences, Murat C. Mungan, Jonathan Klick

All Faculty Scholarship

There is a 250 year old presumption in the criminology and law enforcement literature that people are deterred more by increases in the certainty rather than increases in the severity of legal sanctions. We call this presumption the Certainty Aversion Presumption (CAP). Simple criminal decision making models suggest that criminals must be risk-seeking if they behave consistently with CAP. This implication leads to disturbing interpretations, such as criminals being categorically different than law abiding people, who often display risk-averse behavior while making financial decisions. Moreover, policy discussions that incorrectly rely on criminals’ risk attitudes implied by CAP are ill-informed, and …

Can We Learn Anything About Pleading Changes From Existing Data?, Jonah B. Gelbach

All Faculty Scholarship

In light of the gateway role that the pleading standard can play in our civil litigation system, measuring the empirical effects of pleading policy changes embodied in the Supreme Court's controversial Twombly and Iqbal cases is important. In my earlier paper, Locking the Doors to Discovery, I argued that in doing so, special care is required in formulating the object of empirical study. Taking party behavior seriously, as Locking the Doors does, leads to empirical results suggesting that Twombly and Iqbal have had substantial effects among cases that face Rule 12(b)(6) motions post-Iqbal. This paper responds to …

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 …

Justice, Liability, And Blame: Community Views And The Criminal Law, Paul H. Robinson, John M. Darley
