People in academic departments disagree about who to hire.

In 1991, the University of Minnesota hired Nobu Kiyotaki. Remember that Blanchard and Kiyotaki (1987) was a key innovation in Keynesian economics. The Minnesotans were not doctrinaire about it. They saw a smart and productive guy, hired him, and he went on to do more great things. He now works in the Princeton econ department, with Krugman.
