Racial Matching among African-American and Hispanic Physicians and Patients
研究发现，少数族裔医生拥有更多同族裔患者，但控制专业、执业地点后差异缩小，提示单纯增加少数族裔医生未必能改善服务不足人群的就医机会，但西班牙裔医生的语言能力有特殊作用。
It is widely known that minority doctors have more patients of their own race and ethnicity than would be predicted by random distribution, but most measures of racial matching do not control for physician specialty, practice setting, or location. When we control for these variables, differences by doctor's race are much smaller and, in many cases, not statistically significant, suggesting that simply increasing the number of minority physicians may not be the best way to increase access for under-served populations. However, we do find some evidence of culture-specific human capital (in the form of language ability) for Hispanics.
