Paul Krugman was ill/The Day the Earth Stood Still…
One of the standard charges against believers in smaller government is that we are all fans of Ayn Rand and imagine ourselves as John Galt. I get this thrown at me despite the fact that I have never read a single thing Rand wrote.
Indeed, Paul Ryan got a roasting for his admiration of Rand from New York Times columnist Paul Krugman who called Rand “a very unserious, unreasonable novelist”. And maybe Krugman is right? Perhaps basing your political and economic philosophy on an old science fiction novel is the height of weirdness.
But hang on, what’s this? In an article for the Guardian titled ‘Asimov’s Foundation novels grounded my economics‘, Krugman writes, “I grew up wanting to be Hari Seldon, using my understanding of the mathematics of human behaviour to save civilisation.”
It’s worth reading that again and remembering that it’s from the same man who quotes the well-worn joke about Atlas Shrugged and Lord of the Rings; “the unrealistic fantasy world portrayed in one of those books can warp a young man’s character forever; the other book is about orcs.” If nothing else, at least Krugman’s suggestion that a fake alien invasion could rescue the economy makes a little more sense now.
For those who haven’t waded through Isaac Asimov’s several Foundation novels, Krugman explains:
In Foundation, we learn that a small group of mathematicians [including Krugman’s hero Hari Seldon] have developed ‘psychohistory’ (a) rigorous science of society. Applying that science to the all-powerful Galactic Empire in which they live, they discover that it is in fact in terminal decline, and that a 30,000-year era of barbarism will follow its fall. But they also discover that a carefully designed nudge can change that path…The novels follow the unfolding of that plan
There’s only one brief description of a space battle – and the true purpose of the battle, we learn, is not the defeat of an ultimately trivial enemy but the creation of a state of mind that serves the Plan
There are a series of moments in which the fate of the galaxy seems to hang in the balance… Each of these crises is met by the men of the hour, whose bravery and cunning seem to offer the only hope. Each time, the Foundation triumphs. But here’s the trick: after the fact, it becomes clear that bravery and cunning had nothing to do with it, because the Foundation was fated to win thanks to the laws of psychohistory. Each time, just to drive the point home, the image of Hari Seldon, recorded centuries before, appears in the Time Vault to explain to everyone what just happened.
You can see how Krugman pictures himself. He is one of a small band of Psychokeynesians who possess an insight, the IS/LM model, which enables them to predict the future of economies and gives them the tools – vast deficits and credit expansion – to steer them.
Anything that supports the Psychokeynesian analysis is evidence; anything that doesn’t is simply a ruse. And when the next bit of corroborating evidence floats along, Hari Krugman emerges from a Time Vault to say “told you so”.
But there’s a problem. It’s true that Krugman spotted the housing bubble in 2005 but then he had been calling for it in 2002. This might lead you to question Krugman’s omnipotence. Or you might want to wait for Hari Krugman to appear and explain how this crafty Knight’s Move is actually part of The Plan.
Hari Krugman celebrates his clairvoyance:
The IS-LM model (don’t ask) told us that under depression-type conditions like those we’re experiencing, some of the usual rules would cease to apply: trillion-dollar budget deficits wouldn’t drive up interest rates, huge increases in the money supply wouldn’t cause runaway inflation. Economists who took that model seriously back in, say, early 2009 were ridiculed and lambasted for making such counterintuitive assertions. But their predictions came true.
But considering that they also predicted that this mountain of debt and avalanche of new money would lead to economic recovery then no, their predictions didn’t come true.
Remember former Chair of the Council of Economic Advisors Christina Romer’s prediction that President Obama’s Keynesian stimulus would see American unemployment peak at 8 percent in late 2009 and fall to a little over 5 percent today? Remember that American unemployment actually peaked at over 10 percent in late 2009 and stands at 7.9 percent today?
[I]t’s really important to distinguish between fundamental predictions of a model and predictions that an economist happens to make that don’t really come from the model… [T]he unfortunate Romer-Bernstein prediction of a fairly rapid bounceback from recession reflected judgements about future private spending that had nothing much to do with Keynesian fundamentals, and therefore sheds no light on whether those fundamentals are correct. In short, some predictions matter more than others.
Quite so Paul. Apparently the predictions that come true matter; those that don’t, don’t.
In his Guardian piece Krugman excitedly writes of “the possibility of a rigorous, mathematical social science that understands society, can predict how it changes, and can be used to shape those changes.” Well, looking at the record it’s clear that Hari Krugman hasn’t found it.
Or maybe he has, and we mere mortals simply need to wait for his shimmering likeness to appear from the Time Vault and say “told you so.”
