Effectiveness of In-Season Manager Changes in English Premier League Football

摘要

We analyze the performance effects of in-season manager changes in English Premier League football during the seasons 2000/2001-2014/2015. We find that some managerial changes are successful, while others are counterproductive. On average, performance does not improve following a managerial replacement. The successfulness of managerial turnover depends on specific highly unpredictable circumstances, as we illustrate through case-studies.
