中文摘要

即使在女性受教育和就业机会不断增长的地区,童婚现象依然普遍存在。我们在孟加拉国对一项旨在推迟结婚的经济激励措施以及一项女孩赋权项目进行了实验评估。有资格获得两年激励的女孩未成年结婚的可能性降低了19%,而赋权项目未能减少青少年婚姻。我们表明,这些结果与一个信号模型相一致:在该模型中,新娘类型无法被完全观测,但受偏好的类型(社会保守型女孩)推迟结婚的回报较低。与我们的理论预测一致,我们观察到该激励措施对未受处理的非偏好类型产生了实质性的溢出效应。

Abstract

Child marriage remains common even where female schooling and employment opportunities have grown. We experimentally evaluate a financial incentive to delay marriage alongside a girls' empowerment program in Bangladesh. While girls eligible for two years of incentive are 19 percent less likely to marry underage, the empowerment program failed to decrease adolescent marriage. We show that these results are consistent with a signaling model in which bride type is imperfectly observed but preferred types (socially conservative girls) have lower returns to delaying marriage. Consistent with our theoretical prediction, we observe substantial spillovers of the incentive on untreated nonpreferred types.
