Ethnic inequality and public health
研究了族群不平等与儿童死亡率、孕产妇死亡率、死产、发育迟缓及预期寿命等健康指标的关系，发现这种负面影响在发展中国家和撒哈拉以南非洲尤为显著，并指出避孕使用率和疫苗接种率低是潜在机制。
We examine the association between ethnic inequality and various key health outcomes for a global set of developed and developing countries. Our results show that higher ethnic inequality is associated with a poor state of public health, such as higher child and maternal mortality, increased stillbirths and child stunting, and reduced life expectancy at birth. This set of effects is found to be predominant mainly in developing countries, and Sub-Saharan African countries. Results remain robust to the inclusion of various other measures of inequality, ethnic composition indices, geographic endowments, and other relevant controls. We argue that lower contraceptive usage and poor vaccination rates are potential mechanisms through which ethnic inequality affects health outcomes. Policies targeted at improving public health may need to focus more on these key intermediate channels in ethnic minority regions.
