Linguistic diversity and redistribution

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.The authors wish to thank the nancial support of the Comunidad de Madrid (grant 06/HSE/0157/2004) and of the Fundación BBVAPublicad
