Lessons from Brazil's unsuccessful fiscal decentralization policy to fight COVID-19.

This manuscript investigates the unsuccessful case of the fiscal decentralization policy implemented by the Brazilian central government to help municipalities fight COVID-19. Based on quantitative analyses of data available on governmental websites, we identified that the transfer policy had ignored municipalities' risk patterns and income changes. It benefited municipalities regardless of their vulnerability and population infection risks, and many municipalities reduced healthcare expenditures funded by their revenues during the pandemic.
