This study aims to contribute to the literature by investigating the incentives that pervade agents involved in electoral campaign funding. By means of empirical evidence gathered from the Brazilian electoral financing context, government investment in stocks is analyzed as a possible compensation mechanism for electoral campaign financing. The study investigates government investments in stocks comparing corporations that have supported electoral campaigns and those that have not, by applying the Differences-inDifferences method. By this method, a positive effect of electoral financing on government investment in companies stocks was identified in the 2010 electoral cycle. However, the empirical tests suggest no effect in 2002 and 2006 elections.
