Greg Mankiw has an intriguing post about whether Harvard could or should leave Massachusetts in response to a proposed MA plan to tax large university and college endowments. Mankiw wonders specifically whether the University should create "Harvard South" in another state. I would think Rhode Island would be a natural choice; according to Google Maps, Providence is only about an hour south of Cambridge, and though I've never been there I've heard it's very nice. That raises another interesting question: would colleges and universities be able to shake down state and local governments for subsidies the way pro sports franchises have been able to do? How would Division I sports factor into the bargaining? Given that private schools would have more mobility than public schools--I doubt my alma mater could credibly threaten to move to Atlanta, Seattle, or Los Angeles--how would this change the distribution of resources going into higher education? Perhaps most importantly, how would donors respond? Comments are open if anyone has any ideas (or offers for mortgage refinancing or no-limit Texas Hold 'em).
