我们利用一项旨在随机分配南非一所大型大学室友的政策来调查种族间互动是否会影响刻板印象、态度和表现。通过内隐联想测试，我们发现与不同种族的室友住在一起可以减少白人学生对黑人的负面刻板印象，并增加跨种族友谊。互动也会影响学业成绩：混合房间里的黑人会提高他们的平均绩点（GPA），通过更多的考试，并且辍学率更低。这种积极的影响不是由室友的能力驱动的，室友的偏见越低，这种积极的影响就越强，这表明刻板印象的减少和绩效的提高之间是相辅相成的。 *我们感谢 Nicola Gennaioli、Caroline Hoxby、Michael Kremer、Monica Martinez-Bravo、Rohini Pande、Enrico Rettore、Piero Veronese 以及 NBER 政治经济学、伦敦经济学院 CIFAR、IEA 世界大会、CEPR 公共政策、EUDN、波士顿大学、塔夫茨大学、芝加哥大学、都灵大学、巴黎政治学院、INSEAD、牛津大学、新葡京大学、 Pompeu Fabra、EUI、埃塞克斯大学、IRVAPP、斯德哥尔摩大学、开普敦大学、CERGE-EI 和希伯来大学提供了有用的评论。我们感谢 Selene Ghisolfi 在数据收集和分析方面提供的宝贵帮助。 Nicola Fontana 和 Martina Zanella 提供了出色的研究帮助。 La Ferrara 衷心感谢 ERC Advanced Grant ASNODEV 的财政支持。通常的免责声明适用。 Corno：卡托利卡大学、LEAP 和 IFS，lucia.corno@unicatt.it；拉费拉拉：博科尼大学、LEAP 和 IGIER，eliana.laferrara@unibocconi.it；伯恩斯：开普敦大学，justine.burns@uct.ac.za
We exploit a policy designed to randomly allocate roommates in a large South African university to investigate whether inter-racial interaction affects stereotypes, attitudes and performance. Using Implicit Association Tests, we find that living with a roommate of a different race reduces white students’negative stereotypes towards blacks and increases inter-racial friendships. Interaction also affects academic outcomes: blacks in mixed rooms improve their GPA, pass more exams and have lower dropout rates. This positive effect is not driven by the ability of the roommate and is stronger the lower the roommate’s prejudice, suggesting a complementarity between stereotype reduction and performance gains. ∗We thank Nicola Gennaioli, Caroline Hoxby, Michael Kremer, Monica Martinez-Bravo, Rohini Pande, Enrico Rettore, Piero Veronese and seminar participants at NBER Political Economy, CIFAR at LSE, IEA World Congress, CEPR Public Policy, EUDN, Boston University, Tufts, University of Chicago, University of Turin, SciencesPo, INSEAD, Oxford, Universidade Nova de Lisboa, Pompeu Fabra, EUI, University of Essex, IRVAPP, Stockholm University, University of Cape Town, CERGE-EI and Hebrew University for helpful comments.
