This paper examines the impact of jury racial composition on trial outcomes using a unique data set of felony trials in Florida between 2000 and 2010. 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...

We propose a test of bias based upon patterns of judicial errors. We model the trial court as minimizing a weighted sum of type I and II errors. We define racial bias a situation where the weight depends on defendant/victim race. If the court is unbiased, the error rate should be independent of...

The US criminal justice system is exceptionally punitive. We test whether racial heterogeneity is one cause, exploiting cross-jurisdiction variation in punishment in four Southern states. We estimate the causal effect of jurisdiction on arrest charge outcome, validating our estimates using a...

This paper examines the extent to which criminal conviction rates are affected by the similarity in gender of the defendant and jury. To identify effects, we exploit random variation in both the assignment to jury pools and the ordering of potential jurors. We do so using detailed administrative...

This paper investigates whether judge political affiliation contributes to racial and gender disparities in sentencing using data on over 500,000 federal defendants linked to sentencing judge. Exploiting random case assignment, we find that Republican-appointed judges sentence black defendants...

We shot videos of criminal trials using 3D Virtual Reality (VR) technology, prosecuted by actual prosecutors and defended by actual defense attorneys in an actual courtroom. This is the first paper that utilizes VR technology in a non-computer animated setting, which allows us to replace white...

An extensive literature debates the causes and consequences of the desegregation of American schools in the twentieth century. Despite the social importance of desegregation and the magnitude of the literature, we have lacked a comprehensive accounting of the basic facts of school desegregation....

This paper considers the use of outcomes-based tests for detecting racial bias in the context of police searches of motor vehicles. It shows that the test proposed in Knowles, Persico and Todd (2001) can also be applied in a more general environment where police officers are heterogenous in...

African- American motorist in the United States are much more likely than white motorists to have their car searched by police checking for illegal drugs and other contraband. The courts are faced with the task of deciding on the basis of traffic-search data whether police behavior reflects a...
