This paper analyzes the cost efficiency of Brazilian first league soccer clubs using a Bayesian Varying Efficiency Distribution (VED) model. We confirm that the model fits the data well with all coefficients correctly signed and in line with the theoretical requirements. From the efficiency results, it was clear that the Brazilian soccer league operates at a lower performance in comparison to other international soccer leagues. Factors which contributed to this finding as well as other policy implications are provided.
