A Behavioural Theory of Discrimination in Policing
研究警察在执法中因错误解读犯罪统计数据而导致的种族歧视，即使没有恶意，也会因认知偏差加剧执法不公。
Abstract A large economic literature studies whether racial disparities in policing are explained by animus or by beliefs about group crime rates. But what if these beliefs are incorrect? We analyse a model where officers form beliefs using crime statistics, but do not properly account for the fact that they will detect more crime in more heavily policed communities. This creates a feedback loop where officers over-police groups that they (incorrectly) believe exhibit high crime rates. This inferential mistake can exacerbate discrimination even among officers with no animus and who sincerely believe that disparities are driven by real differences in crime rates.
