Black-white mortality inequalities
利用退休历史调查数据，估计年龄别死亡率中观察到的种族不平等有多少可由风险函数中的变量差异解释，标准变量可解释黑人男性更高死亡率的50%以上。
Racial inequality, particularly between blacks and whites, long has been of major concern in the United States. This inequality may take a number of forms, for example, with regard to schooling, housing, health, employment options, and income. In this paper we estimate how much of the 'observed' racial inequality in age-specific death rates in the Retirement History Survey can be attributed to observed differences in variables in hazard functions. The exact answer depends on what independent variables are excluded, but fairly standard explanatory variables explain 50% to much more of the observed greater death rates of black men.
