What is the effect of corporate dependence on the electoral performance of incumbents? The objective of this paper is to estimate the effect of corporate dependency on the electoral performance of incumbents in the 2016 election. We will test the hypothesis that corporate dependency exerts a negative and significant effect on the electoral success of incumbents. To do so, we will use the election data for city halls in 2012 and 2016 made available by the Superior Electoral Court (TSE) using the R electionsBR1 language package. Methodologically, linear, quantile and logistic regression were used. The main results indicate that: 1) the best voted candidates in 2012 have the greatest chance of winning the 2016 election; 2) the correlation between corporate dependency and revenue balance is close to zero and 3) corporate dependency has no significant effect on election performance and election success of incumbents in 2016.
