Income Inequality, Capitalism, and Ethno-Linguistic Fractionalization
用经济自由指数代表资本主义，研究发现资本主义与总收入基尼系数无稳健关系；民族语言分裂对收入再分配的影响取决于经济自由水平：分裂程度高的国家再分配较少，而资本主义程度高且分裂程度低的国家再分配较多。
We examine the relationship between capitalism and income inequality for a large sample of countries using an adjusted economic freedom index as proxy for capitalism. Our results suggest that there is no robust relationship between economic freedom and Gini coefficients based on gross income. Subsequently, we analyze the relationship between income redistribution and ethno-linguistic fractionalization. We find that the impact of ethno-linguistic fractionalization on income redistribution is conditional on the level of economic freedom: countries that have a high degree of fractionalization redistribute income less, while capitalist countries that have a low degree of fractionalization redistribute income more.
