Rational Expectations and the Ability to Distinguish Cause and Effect Empirically

The Scandinavians award their econ prize to a couple of Keynesian mainstream economists. Ho-hum. This provides another opportunity to point out that the Nobel has also gone to well known figures like Yasir Arafat, Al Gore, and never to be overlooked Barack Hussein Obama.


I would hardly term Sims and Sargent "a couple of Keynesian mainstream economists." They provided the ammunition that munitioned the war that overthrew orthodox Keynesianism as the conventional wisdom of mainstream economics.

Consider the Wall Street Journal, hardly a hotbed of Keynesianism. It rushed to publish David Henderson's commentary, "A Nobel for Non-Keynesians."

Sargent's work led the rational expectations revolution which explains why the recent Keynesian policies are not working.

The Journal called Sims "an active proponent of the 'fiscal theory of the price level,' which suggests that consumer prices aren't merely determined by the money supply... A persistent government budget deficit can cause run-ups in the price level because of the inflationary measures that governments are tempted to take to finance their liabilities."

As for the Nobel electors, the Journal sees it quite differently from you, Westie, "With this year's picks, the Royal Swedish Academy of Sciences upholds its reputation of being less cloistered and distant from reality than some of the other Nobel selectors. It may well be a sign of the times that the Academy selected two economists so at odds with the recent Keynesian vogue."
