In late 2014, California voters passed Proposition 47 that redefined a set of less serious felony drug and property offenses as misdemeanors. We examine how racial and ethnic disparities in criminal court dispositions in San Francisco change in the years before (2010–2014) and after (2015–2016) the passage of Proposition 47. We decompose disparities in court dispositions into components resulting from racial/ethnic differences in offense characteristics, involvement in the criminal justice system at the time of arrest, pretrial detention, criminal history, and the residual unexplained component. Before and after Proposition 47, case characteristics explain nearly all of the observable disparities in court dispositions between racial and ethnic groups. After the passage of Proposition 47, however, there is a narrowing of disparities in convictions and incarceration sentences that is driven by lesser weight placed on criminal history, active criminal justice status, and pretrial detention in effecting court dispositions

减刑对刑事案件结果中种族和族裔差异的影响

2014年底，加利福尼亚州选民通过了第47号提案，该提案将一系列较不严重的重罪毒品和财产犯罪重新定义为轻罪。我们研究了47号提案通过之前（2010-2014年）和之后（2015-2016年），旧金山刑事法院处置中的种族和种族差异是如何变化的。我们将法院处置中的差异分解为种族/民族因素犯罪特征的差异，逮捕时参与刑事司法系统，审前拘留，犯罪记录以及无法解释的剩余部分。在第47号提案之前和之后，案件特征几乎可以解释种族和族裔群体在法院安排中的所有可观察到的差异。但是，提案47通过后，
