TY - GEN AB - Research on sports betting often attempts to identify biased evaluation by bookmakers, opening opportunities for profitable strategies to bettors. Previous studies have provided evidence for the existence of such ineffiiciencies. Since most studies cover only a few seasons, the question of whether market inefficiencies per- sist over time remains unanswered. We analyse the big five leagues in European association football for fourteen seasons to detect the occurrence and duration of market inefficiencies. While our results suggest that most biases do not persist for a long time, we still uncover profitable betting strategies throughout the full observation period.
