We show that recent proposals to reform compensation practices, such as postponing bonuses and instituting clawback provisions, will not eliminate opportunities to game the system unless accompanied by transparency in managers’ positions and strategies. Indeed there exists no compensation mechanism that separates skilled from unskilled managers solely on the basis of their returns histories.
