Sex Workers, Stigma, and Self-Image: Evidence from Kolkata Brothels
通过在印度加尔各答性工作者中开展随机田野实验，研究心理干预能否改善因贫困和社会排斥而面临污名者的自我形象，并发现干预显著提升了自我形象、储蓄选择和健康诊所访问，且效果持续超过一年。
Abstract This paper studies the link between self-image and behavior among those who face stigma due to poverty and social exclusion. Using a randomized field experiment with sex workers in Kolkata (India), we examine whether a psychological intervention to mitigate adverse effects of internalized stigma can induce behavior change. We find significant improvements in participants' self-image, their savings choices, and health clinic visits. Administrative data confirm that these changes in savings and preventive health behavior persist 15 and 21 months later, respectively. Our findings highlight the potential of purely psychological interventions to improve the life choices and outcomes of marginalized groups.
