Managerial turnover has increased and the general view, which I would share, is that this trend has gone too far and the boost obtained by a new manager has been exaggerated.
However, new research takes a different angle on the problem. It splits the Premier League into two halves and finds that there is a boost in the bottom half. Examples in the season just finished would include Sunderland and Crystal Palace, or Crystal Pulis as some now call it.

Why there should be this pattern is not clear, and indeed it would need further work to confirm it. It may be that there is more scope for improving a less strong squad. Or it may be that clubs lower down the Premier League often attract less good or more risky managers in the first place, Crystal Palace and Sunderland again being examples.
