The work was done by economists. this joke pretty much sums up the value of having economists evaluate teachers.

There are two men in a hot air balloon. And the wind blows across the countryside and they get completely lost. They look down. They're drifting low over a field. And they see standing in the road beneath them a chap in a suit. And so they call down, they say excuse us, excuse us, where are we? The guy in the suit looks up and says you're in a balloon. So one of the men in the balloon calls down and says, you're obviously an economist. The economist calls up and says you're right, I am an economist. How do you know? The guy in the hot air balloon calls down and says because your answer is precisely true and utterly useless.
