Types of Contact: A Field Experiment on Collaborative and Adversarial Caste Integration
中文摘要
我估计了合作型与对抗型群际接触的效应。我将来自不同种姓的印度男性随机分配参加板球联赛或作为控制组。联赛参与者面临合作型接触的变化（通过随机分配至同一种姓或混合种姓球队实现）和对抗型接触的变化（通过对手的随机分配实现）。合作型接触增加了跨种姓友谊和贸易效率，并减少了对本种姓的偏袒。相比之下，对抗型接触通常减少了跨种姓互动与效率。参与联赛减少了群际差异，表明在此情境下群际接触的积极方面抵消并超出了其消极方面。(JEL C93, D83, D91, J15, O15, Z13, Z21)
Abstract
I estimate the effects of collaborative and adversarial intergroup contact. I randomly assigned Indian men from different castes to participate in cricket leagues or to serve as a control group. League players faced variation in collaborative contact, through random assignment to homogeneous-caste or mixed-caste teams, and adversarial contact, through random assignment of opponents. Collaborative contact increases cross-caste friendships and efficiency in trade, and reduces own-caste favoritism. In contrast, adversarial contact generally reduces cross-caste interaction and efficiency. League participation reduces intergroup differences, suggesting that the positive aspects of intergroup contact more than offset the negative aspects in this setting.
