A Dam Problem: TVA's Fight Against Malaria, 1926–1951
研究发现田纳西河流域管理局（TVA）的水坝建设增加了疟疾发病率，其隐性健康成本抵消了TVA财政刺激乘数的24%。
The TVA has been applauded for its anti-malaria programs in the Southeast during the 1930s and 1940s. However, the TVA developed their anti-malaria programs because they created lakes suitable for mosquito breeding. To estimate the relationship between the TVA and malaria, I construct a county-level panel data from the Southeast United States. I find that the net effect of the TVA was to increase malaria rates following its construction. Using statistical life value estimates, I find that the hidden malaria cost of the TVA offset 24 percent of the fiscal stimulus multiplier generated by the TVA.
