Some posts generate far more discussion than I expect to—such as the one on university professorships below, which currently has 35 comments.

There’s clearly a fair amount of confusion about the terms of such arrangements.

Which reinforces a point I was trying to make: The return of Larry Summers to Harvard provides a great hook for the Crimson to conduct an in-depth look at university professorships.

One final point about Summers’ return: There’s been much debate about whether he had to return to Harvard or lose his professorship. My hunch is that something would have been worked out if he’d come back after three or four years. Does anyone really believe that, with Bob Rubin and Drew Faust on the Corporation, Harvard would say no to Summers?
