Abstract
This paper examines how water filtration and distribution helped reduce mortality during a cholera outbreak. Using household water contract records and individual mortality data, I analyze the impact of filtered water with an event study approach. The results show that having access to filtered water at home greatly reduced the risk of death. This suggests that water filtration and distribution were key public health measures in lowering mortality from waterborne diseases in the 19th and early 20th centuries. Improvements in urban water systems could have played a major role in the decline of cholera outbreaks and mortality during this period.
期刊介绍:
The Journal of Urban Economics provides a focal point for the publication of research papers in the rapidly expanding field of urban economics. It publishes papers of great scholarly merit on a wide range of topics and employing a wide range of approaches to urban economics. The Journal welcomes papers that are theoretical or empirical, positive or normative. Although the Journal is not intended to be multidisciplinary, papers by noneconomists are welcome if they are of interest to economists. Brief Notes are also published if they lie within the purview of the Journal and if they contain new information, comment on published work, or new theoretical suggestions.
