中文摘要
本文考察改善牙齿健康如何影响经济、社会和心理结果。在一项随机实验中，我们向低收入群体提供包括义齿在内的免费牙科护理，发现该干预对男性和女性的牙齿健康及自我感知的心理健康均产生了显著且持久的影响。对女性而言，治疗带来了自尊的提升、拍照时微笑可能性的提高、短期内就业和收入的改善，以及与伴侣互动的改善。我们未发现治疗在这些方面对男性产生影响。异质性分析表明，对于基线时可见牙齿问题更严重的女性，治疗对劳动力市场结果的影响更大。(JEL D12, D91, I12, J16, O12)
Abstract
This paper examines how improving dental health affects economic, social, and psychological outcomes. In a randomized experiment, we provide a low-income group free dental care, including prostheses, and find significant and persistent impacts on men’s and women’s dental and self-perceived mental health. For women, treatment generates improvement in self-esteem, a higher likelihood of smiling when photographed, short-run improvements in employment and earnings, and improvement in partner interactions. We find no impact for men in these dimensions. Heterogeneity analyses suggest that treatment effects on labor market outcomes are larger for women with more severe visible dental issues at baseline.
