To calculate the disenfranchisement indices we use the Dyen percentage cognate matrix of linguistic distances between Indo-European languages and apply survey and population data on language proficiency in the European Union. We then determine optimal sets of official languages that depend on society's sensitivity against disenfranchisement and comprehensiveness of the chosen language regime. We also discuss the language situation in the European Union after its last enlargement.application/pdftext/plaineng© European Economic AssociationMultilingüismoUnión Europearesearch articleD70O52Z13Economía10.1162/1542476054430799open access7814791Journal of the European Economic Association3
