论文摘要
我们提出了一种报告计划评估如何减少群体之间的差距，例如性别或黑白差距的方法。我们首先表明，组之间差异的降低可以写为每组条件平均治疗效果（CATE）的差异。然后，使用Kitagawa-Oaxaca-blinder式分解，我们强调了如何将这些CATE分解为其他可观察结果中其他可观察到的CATE的差异，而其他观察到的组成差异（例如，“ endowment”）。最后，我们应用这种方法来研究Medicare对美国人获得健康保险的影响。
We propose a method for reporting how program evaluations reduce gaps between groups, such as the gender or Black-white gap. We first show that the reduction in disparities between groups can be written as the difference in conditional average treatment effects (CATE) for each group. Then, using a Kitagawa-Oaxaca-Blinder-style decomposition, we highlight how these CATE can be decomposed into unexplained differences in CATE in other observables versus differences in composition across other observables (e.g. the "endowment"). Finally, we apply this approach to study the impact of Medicare on American's access to health insurance.
