For chief executives and other senior leaders, it is not unusual for 60-80% of their pay to be tied to performance – whether performance is measured by quarterly earnings, stock prices, or something else. And yet from a review of the research on incentives and motivation, it is wholly unclear why such a large proportion of these executives’ compensation packages would need to be variable. First, the nature of their work is unsuited to performance-based pay. As the incoming Chief Executive of Deutsche Bank, John Cryan, recently said in an interview: “I have no idea why I was offered a contract with a bonus in it because I promise you I will not work any harder or any less hard in any year, in any day because someone is going to pay me more or less.”
