Does Monitoring Work?

The piece that is excerpted below was republished this afternoon on a listserv that I subscribe to.  It kind of makes you wonder, if professors loathe the evaluations of their students, by analogy shouldn't employees loathe the evaluations of their supervisors?  If not, why not?

At the U of I, there is a requirement that each employee receive an annual performance review.  Later in the course we'll talk about this sort of evaluation - its strengths and its weaknesses.

Since we talked about monitoring in class today as one source of transaction cost, I thought this piece below would be interesting to you.
