Decentralization and democratic participation: The effect of subnational self-rule on voting in Latin America and the Caribbean

“Previous literature on the consequences of decentralization has demonstrated a positive effect on voter participation in subnational elections. However, does this positive effect also extend to national level elections? This paper evaluates the consequences of decentralization-level political participation. Our approach innovates by disaggregating decentralization to uncover the specific dimensions that matter for voting participation. We argue that self-rule (or the authority that subnational units exercise in their own territory) is closely associated with vertical accountability and positively affects voting participation. Moreover, we find that political dimensions of self-rule matter more than fiscal dimensions. Shared-rule (or the authority that subnational units exercise in the country as a whole) has no significant effect on participation since it is more closely related to horizontal accountability. We test our theory in 20 Latin American and Caribbean countries using a hierarchical model with 2010 data at the national and individual-level
