Decentralization is argued to create incentives for local and regional politicians to be more responsive and accountable to their constituents, but few studies have directly tested this claim. We use survey data from Colombia to examine individual-level evaluations of the degree to which decentralization prompts citizens to view department government as more accountable. We estimate the effect of administrative, fiscal, and political decentralization, controlling for participation, political knowledge, confidence in government, education, and income on perceptions of accountability. Our results indicate that administrative and fiscal decentralization improve perceptions of accountability, while political decentralization does not.
