Exposing corrupt politicians : the effects of Brazil's publicly released audits on electoral

This paper examines whether access to information enhances political accountabil- ity. Based upon the results of Brazil's recent anti-corruption program that randomly audits municipal expenditures of federally-transferred funds, it estimates the e®ects of the disclosure of local government corruption practices upon the re-election success of incumbent mayors. Comparing municipalities audited before and after the elections, we show that the audit policy reduced the incumbent's likelihood of re-election by approximately 20 percent, and was more pronounced in municipalities with radio sta- tions. These ¯ndings highlight the value of information and the role of the media in reducing informational asymmetries in the political process.
