Exposing Corrupt Politicians: The Effect of Brazil's Publicly Released Audits on Electoral Outcomes
Frederico Finan, University of California, Berkeley
Claudio Ferraz, University of California Berkeley
ABSTRACT: This paper examines the extent to which access to information enhances political accountability.
Based upon the results of Brazil’s recent anti-corruption program that randomly audits
municipal expenditures of federally-transferred funds, it estimates the effect of the disclosure of
local government corruption practices upon the re-election success of incumbent mayors in municipal
elections. Comparing municipalities which were randomly audited before the elections
with those audited after, the analysis shows that the disclosure of audit results had a significant
impact on the re-election rates of mayors found to be corrupt. For a one standard deviation increase
in reported corruption, the audit policy reduced the incumbent’s likelihood of re-election
by 25 percent. This effect is more pronounced in municipalities where radio stations are present
and higher levels of corruption are identified. These findings highlight the value of information
and the role of the media in reducing informational asymmetries in the political process, thus
enabling voters to not only hold corrupt politicians accountable but also to reward non-corrupt
politicians.
