Race and Concern for the Environment
利用调查数据发现，少数族裔对环境污染的担忧程度显著高于白人，且这一差异不能仅由社会经济因素和污染暴露解释，暗示居住选择并非种族间污染暴露不均的唯一原因。
We use survey data to document a strong heterogeneity in stated degrees of concern about environmental problems across racial groups. Minorities are significantly more worried about pollution than their white counterparts, even after controlling for socioeconomic factors and pollution exposure. Our finding implies that residential sorting based on heterogeneous financial resources and heterogeneous levels of environmental concern is unlikely to be the only driver of uneven exposure to pollution across racial groups.
