Housing, Health, and Happiness
研究墨西哥大规模水泥地面改造项目对儿童健康和成人幸福感的影响，发现水泥地面显著降低儿童寄生虫感染、腹泻和贫血，改善认知发展，并提升成人生活满意度、降低抑郁和压力。
We investigate the impact of a large-scale Mexican program to replace dirt floors with cement floors on child health and adult happiness. We find that replacing dirt floors with cement significantly improves the health of young children measured by decreases in the incidence of parasitic infestations, diarrhea, and the prevalence of anemia, and an improvement in children's cognitive development. Additionally, we find significant improvements in adult welfare measured by increased satisfaction with their housing and quality of life, as well as by lower scores on depression and perceived stress scales.
