This paper addresses a serious environmental concern in Chile: PM2.5 concentration, a health threat especially affecting the population living in the central and southern communes of Chile. Using housing data for 312 spatial units, along with interpolation techniques to predict air pollution for communes with missing information, we find that, on average, 1 μg/m3 increase in PM2.5 produces a decrease of 4.1 per cent in housing rental prices. These estimates also show an important upward bias in the estimated coefficient when the endogeneity of air pollution is not addressed. An average Chilean household would be willing to pay US$12.31 per month for a one-unit reduction in PM2.5 concentration. Similar monetary values have been found in previous studies for both México and Chile. As with PM2.5 concentration, the average marginal willingness to pay exhibits marked differences across communes. From these results, the study addresses some policy implications and proposes avenues for future research.

空气污染如何影响智利的住房租金价格？智利社区 PM2.5 浓度的经济评估

本文解决了智利严重的环境问题：PM2.5集中，这是一种健康威胁，尤其影响生活在智利中部和南部公社的人口。使用 312 个空间单元的住房数据以及插值技术来预测缺少信息的社区的空气污染，我们发现平均为 1 μg/m3PM增加2.5使住房租金价格下降 4.1%。当未解决空气污染的内生性时，这些估计值还显示出估计系数的重要向上偏差。智利家庭平均愿意为 PM 减少一单位每月支付 12.31 美元2.5浓度。先前对墨西哥和智利的研究发现了类似的货币价值。与 PM 一样2.5集中，平均边际支付意愿在公社之间表现出显着差异。根据这些结果，该研究解决了一些政策影响，并提出了未来研究的途径。
