Congrats to Paul Krugman

An award well deserved, his centripetal versus centrifugal forces work in economic geography will increase in importance as the world becomes more globalized and prosperous.

Also, since my suspicion is that Nobel prize winning economists become more ideological and politically active after winning the award, the science won't lose as much quality research in this case. If we wanted to distribute the award in a maximizing scientific output manner, I think it is better to give it to someone who has already moved in that direction rather than someone still heavily involved in their research.
