The RAI travels to Latin America: Measuring regional authority under regime change

This paper presents a new dataset on regional authority in 27 Latin American and Caribbean countries for 1950–2010 based on the Regional Authority Index (RAI), which makes it possible to compare regional authority over time and across regions. We explain conceptualization, operationalization, and coding decisions with the aim of making judgments explicit, and therefore open to amendment or refutation. We present substantive observations about the variation across countries and over time and discuss the implications and challenges of expanding the RAI to contexts in which democracy and authoritarianism alternate

Language difference and regional authority

This paper draws on research in geography, linguistics, and political science to explain the incidence of language regions and their effect on regional authority. It conjectures a chain of mechanisms beginning with the physical and political barriers to human interaction and culminating with contemporary patterns of regional authority. Using data on 1767 regions in 95 countries, it finds causal power in the claim that the linguistic distinctiveness of a region reflects the ratio of internal interaction to external interaction. Finally, the effects of a language region for regional authority depend decisively on the openness of the political regime
