Public finances sustainability by panel data models with cross-sectional dependence: analysis of Brazilian states

Abstract

This study investigates the sustainability of Brazilian states’ public finances with quarterly revenue and expenses data from 2006 to 2020, aimed at the identification of groups of states that share similar patterns. The technique adopted is a panel data model that avoids mistaken inferences by controlling for cross-dependence among states. We find two clear patterns, from which we identify a fiscally sustainable group of only 9 states and an unsustainable group, comprising the remaining ones.
