Oliver Williamson finally got Nobel!

This morning, I was so happy to hear Oliver Williamson won this year's Nobel prize in economics, together with Elinor Ostrom. I have been wanting and actively betting him to win over the last five years, at least.  Now he finally got it.  But I was a little surprised that Armen Alchian and Oliver Hart were not included, giving their equal contribution to the Firm Theory.  Maybe they will be recognized later.
