Yanks and the Nobel

This has sure been a good year for America in the Nobel Prizes.  I don't know if this is unusual or not, but Americans and American institutions are heavily represented in every single prize except Literature this year.  Congrats to the final two, Elinor Ostrom and Oliver Williamson, who apparently did groundbreaking work showing that social relationships can actually affect the workings of the free market.  Who knew?
