Long-Run Mortality Effects of Vietnam-Era Army Service: Evidence from Australia's Conscription Lotteries
利用澳大利亚征兵抽签的自然实验，研究越战时期陆军服役对长期死亡率的影响，发现服役对总体及各死因死亡率均无显著统计效应。
We estimate the effect of Vietnam-era Army service on mortality, exploiting Australia's conscription lotteries for identification. We utilize population data on deaths during 1994–2007 and military personnel records. The estimates are identified by over 51,000 compliers induced to enlist in the Army. We find no statistically significant effects on mortality overall, nor for any cause of death. The estimated relative risk (RR) of death associated with Army service is 1.03 (95% CI: 0.92, 1.19). On the assumption that Army service affected mortality only for those who served in Vietnam, the estimated RR is 1.06 (95% CI: 0.81, 1.51).
