The Persistence of Corruption: Evidence from the 1992 Presidential Impeachment in Brazil Rita Ramalho∗ The World Bank January 16, 2007 Abstract Corruption imposes substantial economic costs, yet there is little evidence on the success of anti-corruption campaigns. I study the 1992 impeachment of president Collor in Brazil to evaluate its impact on politically connected companies both in the short- and long-term. Using an event study methodology, I establish the short-run e ff ect: family- connected fi rms on average lose 2 to 9 percentage points of their value on dates when information damaging to the impeached president is released. However, this decline is reversed entirely within one year. I conclude that the impeachment had limited success in reducing corruption in Brazil.

Several economic studies have provided evidence of the adverse consequences of corruption (Mauro (1995)). Given the costs of corruption1, it is essential to assess how effective anti- corruption campaigns are.
