Linguistic Diversity and Redistribution
研究语言多样性如何影响国家间的再分配水平，发现考虑语言距离后，多样性显著降低再分配，标准差增加使再分配下降约1个百分点。
This paper investigates the effect of linguistic diversity on redistribution in a broad cross-section of countries. We use the notion of "linguistic distances" and show that the commonly used fractionalization index, which ignores linguistic distances, yields insigni cant results. However, once distances between languages are accounted for, linguistic diversity has both a statistically and economically signi cant effect on redistribution. With an average level of redistribution of 9.5 percent of GDP in our data set, an increase by one standard deviation in the degree of diversity lowers redistribution by approximately one percentage point. We also demonstrate that other measures, such as polarization and peripheral heterogeneity, provide similar results when linguistic distances are incorporated.
