摘要

我们报告了对美国扩大警力对特定种族影响的新经验估计。每增加一名警察，凶杀案就会减少约 0.1 起。按人均计算，黑人受害者对白人受害者的影响是白人受害者的两倍。警力增加也会减少对严重犯罪的逮捕，而对黑人犯罪嫌疑人的逮捕则会减少更多，这意味着警力的增加并不会增加最严重指控中的种族差异。与此同时，规模较大的警察部队逮捕了更多的低级 "生活质量 "犯罪，这意味着对美国黑人的影响不成比例。

Police Force Size and Civilian Race.

We report novel empirical estimates of the race-specific effects of larger police forces in the United States. Each additional police officer abates approximately 0.1 homicides. In per capita terms, effects are twice as large for Black versus White victims. Larger police forces also make fewer arrests for serious crimes, with larger reductions for crimes with Black suspects, implying that police force growth does not increase racial disparities among the most serious charges. At the same time, larger police forces make more arrests for low-level "quality-of-life" offenses, with effects that imply a disproportionate impact for Black Americans.
