Reexamining the Contribution of Public Health Efforts to the Decline in Urban Mortality: Comment
中文摘要
本文回应 Anderson、Charles 和 Rees (2022b) 对我们此前研究所作的评论。在纠正明确无误的数据错误后, 我们修正后的估计表明, 在样本城市和年份中, 市政供水消毒 (过滤) 解释了总死亡率下降的 38%——这一结果与我们原先 43% 的估计相差不大。然而, 对婴儿死亡率的影响小于我们最初的分析。他们的分析与我们的分析之间的差异, 大部分源于对部分干预年份的编码方式以及人口分母的差异, 而这两方面的理想数据均难以获得。(JEL H75, I12, I18, J13, Q18, Q51, Q53)
Abstract
We address points raised by Anderson, Charles, and Rees (2022b), which comments on our prior work. After correcting unambiguous data mistakes, our revised estimates suggest that municipal water disinfection (filtration) explains 38 percent of the total mortality rate decline in our sample cities and years—a result not very different from our original estimate of 43 percent. However, effects on infant mortality rates are smaller than in our original analysis. Much of the difference between their analyses and ours is due to the coding of partial intervention years and to differences in population denominators, for which ideal data are difficult to find.
