Segregation and the Quality of Government in a Cross Section of Countries
利用跨国次国家层面的族群、语言和宗教构成数据，构建隔离指标并处理内生性，发现族群和语言隔离程度越高的国家政府质量越低，信任是重要传导渠道。
We provide a new compilation of data on ethnic, linguistic, and religious composition at the subnational level for a large number of countries. Using these data, we measure segregation of groups within the country. To overcome the endogeneity problem that arises because of mobility and endogenous internal borders, we construct an instrument for segregation. We find that more ethnically and linguistically segregated countries, i.e., those where groups live more spatially separately, have a lower quality of government; there is no relationship between religious segregation and governance. Trust is an important channel of influence; it is lower in more segregated countries.
