Resumo

A incerteza sobre os resultados de eventos esportivos tem sido a motivação de muitos trabalhos em diversas áreas de investigação. Em especial, diversos campeonatos de futebol têm sido estudados analisando o seu desempenho econômico, a eficiência e a competitividade. Neste trabalho são utilizadas diferentes medidas de competitividade de rankings para comparar as classificações dos times no Campeonato Brasileiro de Futebol entre os anos 2007 e 2015. É conhecido que as medidas de competitividade com frequência não apresentam os mesmos resultado. No caso analisado, todas as medidas concordaram em apontar o campeonato de 2007 como o mais competitivo, mas mostraram pequenas diferenças em relação ao menos competitivo.
