Paul v. Paul
It's the battle of the great Pauls! Okay...perhaps one great Paul and one evil Paul (I'll let you decide which is which)...
My take on Krugman here is that he must be disingenuous when Paul talks about competition in currency and Krugman says he "has no idea what that's about." He must be disingenuous because no Nobel laureate could be that ignorant. Paul's referring to one of Nobel-laureate Hayek's most important ideas--and his proposed solution to the problem he highlighted which won him the Nobel prize to begin with!
Anyway, this segment is highly worth watching. It's the battle of the century...well, at least since these guys were around:
