    A Fair and Impartial Jury? The Role of Age in Jury Selection and Trial Outcomes
    (Economic Research Initiatives at Duke (ERID), 2012-02-01) Anwar, S; Bayer, P; Hjalmarsson, R
    This paper uses data from over 700 felony trials in Sarasota and Lake Counties in Florida from 2000-2010 to examine the role of age in jury selection and trial outcomes. The results of the analysis imply that prosecutors are more likely to use their peremptory challenges to exclude younger members of the jury pool, while defense attorneys exclude older potential jurors. Having established that age has an important role in jury selection, the paper employs a research design that isolates the effect of the random variation in the age composition of the pool of eligible jurors called for jury duty to examine the causal impact of age on trial outcomes. Consistent with the jury selection patterns, the empirical evidence implies that older jurors are indeed more likely to convict. These results are robust to the inclusion of a broad set of controls for the racial and gender composition of the jury and a series of county, time, and judge fixed effects; almost identical effects are estimated separately for each county. These findings have implications for the role that the institution of peremptory challenges has on a defendant’s right to a fair trial and to an eligible citizen’s rights to serve on a jury.

    A Jury of Her Peers: The Impact of the First Female Jurors on Criminal Convictions
    (Economic Research Initiatives at Duke (ERID), 2016-02-10) Anwar, S; Bayer, P; Hjalmarsson, R
    This paper uses an original data set of more than 3000 cases from 1918 to 1926 in the Central Criminal Courts of London to study the effect of the Sex Disqualification (Removal) Act of 1919. Implemented in 1921, this Act made females eligible to serve on English juries, providing a novel setting for studying the impact of female representation on jury verdicts. Results based on a pre-post research design imply that the inclusion of females had little effect on overall conviction rates but resulted in a large and significant increase in convictions for sex offenses and on the conviction rate differential between violent crime cases with female versus male victims. The inclusion of women also increased the likelihood of juries being discharged without reaching a verdict on all charges and the average time taken to reach a verdict. A complementary analysis of cases in which the jury was carried over from a previous trial also implies that the inclusion of female jurors on the seated jury sharply increased conviction rates for violent crimes against women versus men.

    Building criminal capital behind bars: Peer effects in juvenile corrections
    (Quarterly Journal of Economics, 2009-02-01) Bayer, P; Hjalmarsson, R; Pozen, D
    This paper analyzes the influence that juvenile offenders serving time in the same correctional facility have on each other's subsequent criminal behavior. The analysis is based on data on over 8,000 individuals serving time in 169 juvenile correctional facilities during a two-year period in Florida. These data provide a complete record of past crimes, facility assignments, and arrests and adjudications in the year following release for each individual. Tb control for the nonrandom assignment to facilities, we include facility and facility-by-prior-offense fixed effects, thereby estimating peer effects using only within-facility variation over time. We find strong evidence of peer effects for burglary, petty larceny, felony and misdemeanor drug offenses, aggravated assault, and felony sex offenses. The influence of peers primarily affects individuals who already have some experience in a particular crime category. We also find evidence that the predominant types of peer effects differ in residential versus nonresidential facilities; effects in the latter are consistent with network formation among youth serving time close to home. © 2009 by the President and fellows of Harvard College and the Massachusetts Institute of Technology.

    Politics in the Courtroom: Political Ideology and Jury Decision Making
    (Economic Research Initiatives at Duke (ERID), 2015-04-01) Anwar, S; Hjalmarsson, R; Bayer, P
    This paper uses data from the Gothenburg District Court in Sweden and a research design that exploits the random assignment of politically appointed jurors (termed nämndemän) to make three contributions to the literature on jury decision-making: (i) an assessment of whether systematic biases exist in the Swedish nämndemän system, (ii) causal evidence on the impact of juror political party on verdicts, and (iii) an empirical examination of the role of peer effects in jury decision-making. The results reveal a number of systematic biases: convictions for young defendants and those with distinctly Arabic sounding names increase substantially when they are randomly assigned jurors from the far-right (nationalist) Swedish Democrat party, while convictions in cases with a female victim increase markedly when they are assigned jurors from the far-left (feminist) Vänster party. The results also indicate the presence of peer effects, with jurors from both the far-left and far-right parties drawing the votes of their more centrist peers towards their positions. Peer effects take the form of both sway effects, where jurors influence the opinions of their closest peers in a way that can impact trial outcomes, and dissent aversion, where jurors switch non-pivotal votes so that the decision is unanimous.

    The role of age in jury selection and trial outcomes
    (Journal of Law and Economics, 2014-01-01) Anwar, S; Bayer, P; Hjalmarsson, R

All rights reserved. 0022-2186/2014/5704-0039$10.00This paper uses data from more than 700 felony trials in Florida to examine the role of age in jury selection and trial outcomes. The results imply that prosecutors are more likely to use their peremptory challenges to exclude younger members of the jury pool, while defense attorneys exclude older potential jurors. To examine the causal impact of age, we employ a research design that isolates the effect of the random variation in the age composition of the pool of eligible jurors called for jury duty. Consistent with the jury selection patterns, the empirical evidence implies that older jurors are significantly more likely to convict. Results are robust to controls for county, time, and judge fixed effects. Thus, many cases are decided differently for reasons that are completely independent of the nature of the evidence in the case—that is, there is substantial randomness in the application of criminal justice.
