Does When You Die Depend on Where You Live? Evidence from Hurricane Katrina
研究了卡特里娜飓风对原住新奥尔良的老年幸存者长期死亡率的影响，发现迁移到低死亡率地区解释了大部分生存率提升，并量化了居住地对死亡率的影响。
We follow Medicare cohorts to estimate Hurricane Katrina’s long-run mortality effects on victims initially living in New Orleans. Including the initial shock, the hurricane improved eight-year survival by 2.07 percentage points. Migration to lower-mortality regions explains most of this survival increase. Those migrating to low- versus high-mortality regions look similar at baseline, but their subsequent mortality is 0.83–1.01 percentage points lower per percentage point reduction in local mortality, quantifying causal effects of place on mortality among this population. Migrants’ mortality is also lower in destinations with healthier behaviors and higher incomes but is unrelated to local medical spending and quality.
