Hey, when I visited Georgetown, I did not have the feeling that the professors were particularly interested in working together with people from the Fund or the Bank - I applied there particularly in the hope of being at a university with a serious applied focus, but Georgetown had the exact opposite feel: That Georgetown, being in DC, was making even more of an effort than other places to brand themselves as an "academic" institution, not an "applied" one (if you can even make such a difference). Also, their sincere interest in moving up the rankings is hampered by placing people in the Bank or the Fund, and by professors doing lots of consulting rather than academic writing, so I had the feeling they were almost trying to discourage it!
Just my experience...
