讲座内容摘要:

Access to healthcare in rural communities of the developing world is often limited and delayed. Many school-aged children in rural areas do not have access to essential health screenings, including vision checks. This paper presents evidence showing that vision screenings enable individuals to access accurate vision health information and treatment which can offer potentially large social benefits. We implement a multiple-year follow-up vision screening program covering children in primary to secondary schools in rural counties of northwestern China. Using a cohort difference-in-differences approach, which takes advantage of variations in the timing of the program's rollout, we find that the vision screening program positively impacts its participants' vision. The effectiveness of the program is influenced by children's subsequent behavior. The positive impact on vision is more pronounced when the vision screening is paired with free eyeglasses vouchers for those in need, when students take up this offer, or if information friction is less through better internet access.

发展中国家的农村社区获得医疗保健的机会往往有限且延迟。农村地区的许多学龄儿童无法获得必要的健康检查,包括视力检查。本文提供的证据表明,视力筛查使个人能够获得准确的视力健康信息和治疗,这可以提供潜在的巨大社会效益。我们实施了一项为期多年的视力筛查随访计划,覆盖中国西北部农村县的小学至中学儿童。使用队列差异差异方法,该方法利用计划推出时间的差异,我们发现视力筛查计划对其参与者的视力产生积极影响。该计划的有效性受到儿童后续行为的影响。当视力筛查与有需要的人的免费眼镜券配对时,对视力的积极影响更加明显,当学生接受此优惠时,或者如果通过更好的互联网访问减少信息摩擦。
