Some electoral systems in Brazil were compared to see if they produce better politicians. The study found that candidates in single-ballot and dual-ballot elections are similar in age, education, and skills. However, dual-ballot elections have fewer women in top positions. Both types of mayors spend similar amounts on campaigns and have similar reelection rates. Dual-ballot mayors attract more discretionary transfers in election years when they can run again. This suggests that the experience required for dual-ballot elections may give candidates skills that help them in the electoral process. Unfortunately, this may disadvantage female candidates due to historical low participation of women in politics.
