We investigate the impacts of turnover of head coaches upon team performance in the context of brazilian football. Since team s outcomes in a given season are important determinants of revenues and potential goals for next seasons, we try to examine empirically if replacing the head coach is an efficient way to increase performance. Importantly, we try to deal with selection into turnover by relying on within team-season variation and by comparing teams in similar positions on the table. Our preferred specification shows that teams that replace the head coach experience an increase in 30 per cent in the probability of winning at least two of the 6 games following a turnover. These impacts seem to hold for teams at top positions, but do not for teams at bottom of the table. For those, the impacts of turnover seem to be null or at least a decrease in the probability of losing a subsequent match. Further analysis will add non-parametric methods to deal with selection bias.
