中文摘要
我们考察了2006年至2014年间美国中等规模通勤区收入波动性与预期寿命之间的关系。我们使用商业数据集InfoUSA衡量收入波动性，并将其与按性别、县、种族和收入划分的预期寿命估计值相链接。我们发现，一个县较高的收入波动性与较低的预期寿命相关，但这种关联仅存在于收入分布的底部，且主要体现在非西班牙裔白人群体中。尽管我们无法将研究发现外推到个体层面的关系，但我们确实将其与关于死亡率地域差异以及波动性与健康关系的现有文献联系起来。
Abstract
We examine the relationship between income volatility and life expectancy in mid-sized U.S. commuting zones between 2006 and 2014. We use a commercial dataset, InfoUSA, to measure income volatility which we link to estimates of life expectancy by gender, county, race, and income. We find that higher income volatility in a county is associated with lower life expectancy, but only at the bottom of the income distribution and primarily for non-Hispanic Whites. Though we cannot extrapolate our findings to individual-level relationships, we do link them to existing literatures on place-based differences in mortality and the relationship between volatility and health.
