Lower-income Americans are suffering from declines in income, health, and longevity over time. Income and employment policies have been proposed as a potential non-medical solution to this problem.
An interrupted time series analysis of state-level incremental supplements to the Earned Income Tax Credit (EITC) program was performed using data from 1993 to 2010 Behavioral Risk Factor Surveillance System surveys and state-level life expectancy. The cost effectiveness of state EITC supplements was estimated using a microsimulation model, which was run in 2015.
Supplemental EITC programs increased health-related quality of life and longevity among the poor. The program costs about $7,786/quality-adjusted life-year gained (95% CI=$4,100, $13,400) for the average recipient. This ratio increases with larger family sizes, costing roughly $14,261 (95% CI=$8,735, $19,716) for a family of three.
State supplements to EITC appear to be highly cost effective, but randomized trials are needed to confirm these findings.
随着时间的推移，美国低收入人群的收入、健康状况和寿命都在下降。收入和就业政策已被提议作为解决这一问题的潜在非医疗方案。
利用1993年至2010年行为风险因素监测系统调查数据和州级预期寿命，对劳动所得税抵免（EITC）计划的州级增量补贴进行中断时间序列分析。使用2015年运行的微观模拟模型估计州EITC补贴的成本效益。
补充EITC计划提高了穷人与健康相关的生活质量和寿命。该计划使平均受助者每获得一个质量调整生命年的成本约为7,786美元（95%置信区间=4,100美元，13,400美元）。这个比率随着家庭规模的增大而增加，对于一个三口之家来说，成本约为14,261美元（95%置信区间=8,735美元，19,716美元）。
州对EITC的补贴似乎具有很高的成本效益，但需要随机试验来证实这些发现。
