Does Diversity Matter for Health? Experimental Evidence from Oakland
通过随机实验，研究黑人男性在遇到同种族医生后，更愿意接受预防性医疗服务，尤其是侵入性服务，并估计这能缩小黑白男性心血管死亡率差距的19%。
We study the effect of physician workforce diversity on the demand for preventive care among African American men. In an experiment in Oakland, California, we randomize black men to black or non-black male medical doctors. We use a two-stage design, measuring decisions before (pre-consultation) and after (post-consultation) meeting their assigned doctor. Subjects select a similar number of preventives in the pre-consultation stage, but are much more likely to select every preventive service, particularly invasive services, once meeting with a racially concordant doctor. Our findings suggest black doctors could reduce the black-white male gap in cardiovascular mortality by 19 percent.
