Money is a lousy way to motivate people

I once argued UN salaries shouldn't be so high as these were, in my view, responsible for the low effectiveness of the institution. Most people disagree. But academic research seems to be on my side. There is more and more evidence that monetary rewards crowd-out intrinsic motivation and are counterproductive for public prosocial activities. I tried to support my claim with more evidence... Now, on his excellent blog, Eric Barker throws a bunch of examples. Anybody with me?
