But it's not just a theoretical question. I was in a meeting in a company recently where the board rep didn't even bother arguing that performance-related rewards "work" to increase performance. They accepted our argument that it's basically junk. I suspect that a lot of board members accept this but - as this company suggested - investors don't give them a consistent message, and it's very hard to be the first mover.
Unfortunately most investors haven't really thought at all about the effectiveness of performance pay and most still seem to believe it is an unquestionably Good Thing. The most depressing result of this is investors getting hung up on trying to tie rewards to non-financial factors to try and encourage good behaviour (if you buy the overjustification/motivation crowding stuff this is actually a very Bad Idea).
Therefore, in my opinion, the best thing we can hope to currently is to try and undermine belief in the value of performance-related rewards. If you're interested in joining my little crusade on this topic, here's a list of pretty easy reading books that will give you more ammo...
