The Presence of Incumbents Electoral Competition and Reelection in Brazil (1990-2014)

We analyzed data on the seven last Brazilian national elections (1990-2014). We employed descriptive (variable measures and times series) and inferential statistics (regression analysis with panel data). Our main findings: 01. the percentage and [...]
