I don't read the economic academic literature but does Krugman actually publish anything other then political rants? Does he have an academic publishing record?
Am I to believe his contributions to the field are on par with James Buchanon, Hayek, Nash to name a few?
A there been any other political commentators to get the prize in it's history?
No. This is like Al Gore getting the Nobel prize. Its all political now. They just keep hyping and lauding each other. Every professor of economics publishes papers. That's how you get the be a life-tenured Lefty. His stuff is middling at best.
