Jury Discrimination in Criminal Trials
Shamena Anwar, Patrick Bayer & Randi Hjalmarsson
NBER Working Paper, September 2010
Abstract:
This paper examines the impact of jury racial composition on trial outcomes using a unique dataset of all felony trials in Sarasota County, Florida between 2004 and 2009. We utilize a research design that exploits day-to-day variation in the composition of the jury pool to isolate quasi-random variation in the composition of the seated jury. We find strong evidence that all-white juries acquit whites more often and are less favorable to black versus white defendants when compared to juries with at least one black member. Using the Anwar-Fang rank order test, we find strong statistical evidence of discrimination on the basis of defendant race. These results are consistent with racial prejudice on the part of white jurors, black jurors, or both. Using a simple model of jury selection and decision-making, we replicate the entire set of empirical regularities observed in the data, including the fact that blacks in the jury pool are just as likely as whites to be seated. Simulations of the model suggest that jurors of each race are heterogeneous in the standards of evidence that they require to convict and that both black and white defendants would prefer to face jurors of the same race.

A Simple Model Of Optimal Hate Crime Legislation
Li Gan, Roberton Williams & Thomas Wiseman
Economic Inquiry, forthcoming
Abstract:
We present a simple model of the effects of hate crime legislation. We show that even if the direct harm to victims of hate crime is the same as for other crimes, because of other differences in the effects it may still be optimal to exert a different level of law-enforcement effort to deter or prevent hate crime. These differences also have previously unrecognized effects on the optimal level of effort by potential hate crime victims to avoid being victimized, thus affecting the efficiency of government policies that encourage or discourage such effort. In some cases, the optimal level of government effort may be lower for hate crimes than for other crimes. Our analysis suggests a role for policy tools that influence individual avoidance effort directly. We discuss the implications of our results for similar types of crime, including terrorism.

Racial-Ethnic Intolerance and Support for Capital Punishment: A Cross-National Comparison
James Unnever & Francis Cullen
Criminology, August 2010, Pages 831-864
Abstract:
This article tests cross-nationally the minority group threat thesis that public sentiments toward repressive crime-control policies reflect conflicted racial and ethnic relations. Using multiple data sets representing France, Belgium, the Netherlands, East and West Germany, Italy, Luxembourg, Denmark, Great Britain, Greece, Spain, Finland, Sweden, Austria, Canada, Ireland, and Portugal, we examine whether racial and ethnic intolerance - animus, resentments, or negative sentiments toward minorities - predicts greater support for the death penalty. Our results reveal that the respondents were significantly more likely to express support for capital punishment if they were racially or ethnically intolerant while controlling for other covariates of public opinion. These findings indicate that the link between support for capital punishment and racial and ethnic animus may occur universally in countries with conflicted racial and ethnic relations.

Cost-benefit analysis of reducing crime through electronic monitoring of parolees and probationers
Stuart Yeh
Journal of Criminal Justice, forthcoming
Objective: The objective of this study was to estimate the benefits and costs of using electronic monitoring (EM) and home detention to reduce crime committed by parolees and probationers.
Method: Data from a national survey of state prison inmates was adjusted and used to estimate the number of crimes that would have been committed by all parolees and probationers over the course of one year in the absence of EM and home detention. The data were analyzed in combination with existing analyses of the effectiveness and costs of EM and home detention and the economic costs of crime to estimate the benefit-cost ratio of nationwide implementation of EM and home detention with all parolees and probationers.
Results: EM plus home detention could avert an estimated 781,383 crimes every year. The social value of the annual reduction in crime is $481.1 billion. Society would gain $12.70 for every dollar expended on the proposed intervention.
Conclusion: EM plus home detention could be an effective deterrent to crime and could have enormous social benefits, especially if it is applied early and saves what would otherwise be habitual offenders from a life of crime.

Violent Video Games Cause an Increase in Aggression Long After the Game Has Been Turned Off
Brad Bushman & Bryan Gibson
Social Psychological and Personality Science, forthcoming
Abstract:
Experimental studies show that violent video games cause people to behave more aggressively, but how long does the effect last? In most experiments, aggression is measured immediately after gameplay. The present experiment is the first to test the long-term causal effects of violent video games on aggression. By the flip of a coin, participants played a violent or nonviolent game for 20 min. Within each group, half ruminated about the game. The next day, participants competed with an ostensible opponent on a competitive task in which the winner could punish the loser with painful noise blasts through headphones. Results showed that violent video games increased aggression 24 hr later, but only among men who ruminated about the game. Rumination keeps aggressive thoughts, feelings, and behavioral tendencies active. If players ruminate about the violence in a game, the aggression-stimulating effects of the game persist long after it has been turned off.

"Fair and Balanced?" Justice Issues on Political Talk Shows
Sarah Britto & Dean Dabney
American Journal of Criminal Justice, December 2010, Pages 198-218
Abstract:
Like their news program predecessors, many political talk shows focus a considerable amount of their coverage on justice issues. Although numerous past studies have examined justice issue presentation in news programs, infotainment, and crime drama, to date only one forthcoming study has examined crime and justice coverage on political talk shows. Political talk shows often present issues in a debate format, as well as emphasize the balanced nature of the content in advertising, with one program even using the slogan "fair and balanced." Building upon the format of previous media studies, we analyzed a composite month of videotaped footage of three popular political talk shows appearing on cable networks: CNN's Lou Dobbs Tonight, MSNBC's Hardball with Chris Mathews, and The O'Reilly Factor from the Fox News Channel. Using content analysis techniques, this study examines balance in the form and content of these programs in terms of presentation of justice issues, political party identification of hosts and guests and realistic presentations of race and gender in the context of crime and justice. Results indicate that these programs tend to adopt an advocacy tone rather than an objectivist one. Furthermore, we demonstrate that racial and gender portrayals of crime and justice on these shows are significantly distorted from reality, with a priority afforded to white female victims of violent crime and minority male offenders.

Racial Tensions and School Crime
Michael Maume, Yeoun Soo Kim-Godwin & Caroline Clements
Journal of Contemporary Criminal Justice, August 2010, Pages 339-358
Abstract:
This article uses data on school crime and other characteristics from a study of U.S. public schools to contribute to our knowledge about the extent and correlates of school violence and property crime. Following a brief review of the literature, the authors describe their efforts to examine the link between racial tensions and school crime. Relying on the macro version of general strain theory (GST) developed by Agnew and racial contact/threat perspectives on school race relations, a more specific purpose for their article is to determine the extent to which school-based crime is at least a partial function of extant racial tensions in schools. Analyses of violent and property-related incidents across a weighted sample of 1,936 middle and high schools indicate that racial tensions is a significant, positive correlate of both types of school crime, net of other school climate, organizational, and demographic characteristics. They discuss these findings and describe directions for future research with these data.

Understanding the Effects of Antiprofiling Policies
Paul Heaton
Journal of Law and Economics, February 2010, Pages 29-64
Abstract:
Many police agencies have enacted measures designed to reduce racial profiling, yet little empirical evidence exists regarding the effects of such programs. This article uses the occurrence of a racial profiling scandal in New Jersey to quantify the effect of a move toward race‐neutral policing. The scandal and subsequent reforms led to an estimated 16-33 percent decrease in annual arrests of minorities for motor vehicle theft. I also present evidence that, as policing against minorities decreased, motor vehicle theft increased in areas populated by minorities. My implied elasticities do not suggest that minorities respond to policing intensity differently than the general population. New Jersey data generate little strong evidence of additional adverse responses by minorities to lessened police scrutiny. The findings are robust to a number of specification checks, and similar patterns are observable in Maryland, a state that experienced a profiling scandal several years before New Jersey.

Christopher Browning et al.
Journal of Research in Crime and Delinquency, August 2010, Pages 329-357
Abstract:
Drawing on Jacobs's (1961) and Taylor's (1988) discussions of the social control implications of mixed land use, the authors explore the link between commercial and residential density and violent crime in urban neighborhoods. Using crime, census, and tax parcel data for Columbus, Ohio, the authors find evidence of a curvilinear association between commercial and residential density and both homicide and aggravated assault, consistent with Jacobs's expectations. At low levels, increasing commercial and residential density is positively associated with homicide and aggravated assault. Beyond a threshold, however, increasing commercial and residential density serves to reduce the likelihood of both outcomes. In contrast, the association between commercial and residential density and robbery rates is positive and linear. The implications of these findings for understanding the sources of informal social control in urban neighborhoods are discussed.

Psychopaths Are Impaired in Social Exchange and Precautionary Reasoning
Elsa Ermer & Kent Kiehl
Psychological Science, forthcoming
Abstract:
Psychopaths show a profound lack of morality and behavioral controls in the presence of intact general intellectual functioning. Two hallmarks of psychopathy are the persistent violation of social contracts (i.e., cheating) and chronic, impulsive risky behavior. These behaviors present a puzzle: Can psychopaths understand and reason about what counts as cheating or risky behavior in a particular situation? We tested incarcerated psychopaths' and incarcerated nonpsychopaths' reasoning about social contract rules, precautionary rules, and descriptive rules using the Wason selection task. Results were consistent with our hypotheses: Psychopaths (compared with matched nonpsychopaths) showed significant impairment on social contract rules and precautionary rules, but not on descriptive rules. These results cannot be accounted for by differences in intelligence, motivation, or general antisocial tendency. These findings suggest that examination of evolutionarily identified reasoning processes can be a fruitful research approach for identifying which specific mechanisms are impaired in psychopathy.

Abstract:
Despite mixed empirical evidence regarding the ability of the Psychopathy Checklist - Revised (PCL-R) to predict violence among incarcerated inmates, it continues to be used to address such questions, even in the context of capital cases. The purpose of this study was to examine if the PCL-R has a prejudicial effect on mock jury members during the sentencing phase of a capital murder trial. Results indicated that participants were more likely to sentence the defendant to death when the defendant exhibited a high likelihood to commit future violence, whether or not the diagnostic label "psychopath" was present. Interestingly, when asked to rate the defendant's likelihood for future violence and murder, the defendant who was a high risk for future violence and not labeled a psychopath received the highest rating. These results suggest an absence of juror bias as it pertains to the label "psychopath" when sentencing a defendant in a capital murder case.

Laura Hickman & Marika Suttorp
Crime Delinquency, October 2010, Pages 507-534
Abstract:
Previously deported aliens are a group about which numerous claims are made but very few facts are known. Using data on male deportable aliens released from a local jail, the study sought to test the ubiquitous claim that they pose a high risk of recidivism. Using multiple measures of recidivism and propensity score weighting to account for preexisting group differences, the authors find consistent support for the assertion that previously deported aliens are a high recidivism risk. Relative to similarly situated deportable aliens with no record of deportation, previously deported aliens are more likely to be rearrested, to be rearrested more quickly, and to be rearrested more frequently in a 1-year follow-up period.

Evaluation of Efficiency in Crime Control and Crime Prevention Programs
John Carroll, Efraim Ben-Zadok & Clifford McCue
American Journal of Criminal Justice, December 2010, Pages 219-235
Abstract:
The purpose of the study is to evaluate and compare the efficiency of crime control and crime prevention programs. The focus on efficiency adds knowledge about quality of performance in criminal justice programs. The case study covers twelve-year implementation process of two juvenile justice programs in a local law enforcement agency. A Truancy Reduction Program (TRP) represents the crime control approach. A School Resource Officer Program (SROP) represents the crime prevention approach. The evaluation shows that the SROP produced far more efficient results than the TRP. The SROP demonstrates gradual improvement and efficient implementation. The TRP appears inefficient and, therefore, should have been revised in the midst of the implementation period. The study draws policy implications for designing more efficient crime control and crime prevention programs. The implications can be useful for law enforcement agencies that contemplate or implement such programs.

The Reproduction of Racial Inequality: How Crime Affects Housing Turnover
Min Xie & David McDowall
Criminology, August 2010, Pages 865-896
Abstract:
This study examines the microlevel process of housing turnover between Blacks and Whites to assess whether crime plays an important role in the racial transition of neighborhoods. The study uses a unique, longitudinal version of the National Crime Survey in which each dwelling's close neighbors are identified. After controlling for household characteristics and the characteristics of their close neighbors, crime occurring in nearby areas is found to increase the chances of White-to-Black turnover while decreasing the chances of Black-to-White turnover. This change occurs even though the directly victimized houses do not necessarily have a probability of racial turnover different than that of other houses nearby. The findings suggest the presence of structural constraints that limit the housing opportunities for Blacks and constrain their choice of residence to comparatively unsafe neighborhoods. They also indicate that "White avoidance," in which Whites systematically bypass high-crime neighborhoods, is important in maintaining the relationship between race and crime.

Optimal Bail and the Value of Freedom: Evidence from the Philadelphia Bail Experiment
David Abrams & Chris Rohlfs
Economic Inquiry, forthcoming
Abstract:
This article performs a cost-benefit analysis to determine socially optimal bail levels for felony defendants. We consider jailing costs, the cost of lost freedom to incarcerated defendants, and the social costs of flight and new crimes committed by released defendants. We estimate the effects of changing bail using data from a randomized experiment. We find that the typical defendant in our sample would be willing to pay roughly $1,000 for 90 d of freedom. While imprecise, our optimal bail estimates are similar to the observed levels of bail prior to bail reform.

For the Longest Time: The Adjustment of Inmates to a Sentence of Life Without Parole
Margaret Leigey
Prison Journal, September 2010, Pages 247-268
Abstract:
Using a triangulated research design, this research examines the mental health of life without parole (LWOP) inmates. A bivariate analysis of the mental health of two groups of LWOP inmates was conducted, new (n = 72) and veteran (n = 46). New LWOP inmates were defined as those who had served less than the mean number of years of the sample (10.5 years) while veteran LWOP inmates had served greater than the mean time served. Results indicate that the initial stages of incarceration are particularly stressful as a higher prevalence of new LWOP inmates reported mental health disorder than veteran LWOP inmates. Significant differences exist between the two groups in several areas. In-depth interviews with veteran LWOP inmates (n = 25) are further indicative of an inverse relationship between mental disorder and length of incarceration.

Naomi Sadeh et al.
Journal of Abnormal Psychology, August 2010, Pages 604-609
Abstract:
Although prior research has examined the genetic correlates of antisocial behavior, molecular genetics influences on psychopathic traits remain largely unknown. Consequently, we investigated the influence of polymorphic variation at the serotonin transporter protein gene (SLC6A4) and socioeconomic resources (SES) on psychopathic traits in youth across two distinct samples in two separate studies. In Study 1, a main effect of serotonin transporter (5-HTTLPR) genotype was associated with the impulsivity dimension of psychopathy. That is, individuals homozygous for the short allele evidenced more impulsivity than did those homozygous for the long allele. In contrast, a gene-environment interaction was associated with the callous-unemotional and narcissistic features of psychopathy. Callous-unemotional and narcissistic traits increased as SES decreased only among youths with the homozygous-long (l/l) genotype, a novel finding replicated and extended in Study 2. These studies provide preliminary results that the l/l genotype confers risk for the emotional deficits and predatory interpersonal traits associated with psychopathy among youths raised in disadvantaged environments.

Rehabilitated or Not: An Informational Theory of Parole Decisions
Dan Bernhardt, Steeve Mongrain & Joanne Roberts
Journal of Law, Economics, and Organization, forthcoming
Abstract:
We consider a parole board that learns about inmates' rehabilitation statuses from observing actions in prison. We show why a board would release one inmate, but not otherwise observationally identical inmates with longer sentences: greater parole board discretion makes additional information more valuable. Consequently, increasing sentences can lead to even greater increases in expected time served. We determine how sentence length affects rehabilitation incentives. To encourage effort, sentences cannot be too short, but when inmates are sufficiently impatient, long sentences may also be undesirable. We show how different parole board priors can support multiple equilibria in rehabilitation effort and investigate the effects of discretion restrictions like parole eligibility.
