What's A Krugman Hater To Do?

The answer? Revel in this: How did Paul Krugman get it so Wrong?

Many friends and colleagues have asked me what I think of Paul Krugman’s New York Times Magazine article, “How did Economists get it so wrong?”

Most of all, it’s sad. Imagine this weren’t economics for a moment. Imagine this were a respected scientist turned popular writer, who says, most basically, that everything everyone has done in his field since the mid 1960s is a complete waste of time. Everything that fills its academic journals, is taught in its PhD programs, presented at its conferences, summarized in its graduate textbooks, and rewarded with the accolades a profession can bestow, including multiple Nobel prizes, is totally wrong. Instead, he calls for a return to the eternal verities of a rather convoluted book written in the 1930s...

It gets worse. Krugman hints at dark conspiracies, claiming “dissenters are marginalized.” Most of the article is just a calumnious personal attack on an ever-growing enemies list, which now includes “new Keyenesians” such as Olivier Blanchard and Greg Mankiw. Rather than source professional writing, he plays gotcha with out-of-context second-hand quotes from media interviews. He makes stuff up, boldly putting words in people’s mouths that run contrary to their written opinions. Even this isn’t enough: he adds cartoons to try to make his “enemies” look silly, and puts them in false and embarrassing situations. He accuses us of adopting ideas for pay, selling out for “sabbaticals at the Hoover institution” and fat “Wall street paychecks.” It sounds a bit paranoid.

It’s annoying to the victims, but we’re big boys and girls. It’s a disservice to New York Times readers. They depend on Krugman to read real academic literature and digest it, and they get this attack instead. And it’s ineffective. Any astute reader knows that personal attacks and innuendo mean the author has run out of ideas.

That’s the biggest and saddest news of this piece: Paul Krugman has no interesting ideas whatsoever about what caused our current financial and economic problems, what policies might have prevented it, or what might help us in the future, and he has no contact with people who do. “Irrationality” and advice to spend like a drunken sailor are pretty superficial compared to all the fascinating things economists are writing about it these days.

How sad.

This is from John Cochrane of the University of Chicago Booth School of Business, and, as you can tell, he has had it with the intellectual dishonesty that is Paul Krugman. And he's pretty much dead on as to why.

So what is Krugman up to? Why become a denier, a skeptic, an apologist for 70 year old ideas, replete with well-known logical fallacies, a pariah? Why publish an essentially personal attack on an ever-growing enemies list that now includes practically every professional economist? Why publish an incoherent vision for the future of economics?

The only explanation that makes sense to me is that Krugman isn’t trying to be an economist, he is trying to be a partisan, political opinion writer. This is not an insult. I read George Will, Charles Krauthnammer and Frank Rich with equal pleasure even when I disagree with them. Krugman wants to be Rush Limbaugh of the Left.

Alas, to Krugman, as to far too many ex-economists in partisan debates, economics is not a quest for understanding. It is a set of debating points to argue for policies that one has adopted for partisan political purposes. “Stimulus” is just marketing to sell Congressmen and voters on a package of government spending priorities that you want for political reasons. It’s not a proposition to be explained, understood, taken seriously to its logical limits, or reflective of market failures that should be addressed directly.

Why argue for a nonsensical future for economics? Well, again, if you don’t regard economics as a science, a discipline that ought to result in quantitative matches to data, a discipline that requires crystal-clear logical connections between the “if” and the “then,” if the point of economics is merely to provide marketing and propaganda for politically-motivated policy, then his writing does make sense. It makes sense to appeal to some future economics – not yet worked out, even verbally – to disdain quantification and comparison to data, and to appeal to the authority of ancient books as interpreted you, their lone remaining apostle.

Most of all, this is the only reason I can come up with to understand why Krugman wants to write personal attacks on those who disagree with him. I like it when people disagree with me, and take time to read my work and criticize it. At worst I learn how to position it better. At best, I discover I was wrong and learn something. I send a polite thank you note.

Krugman wants people to swallow his arguments whole from his authority, without demanding logic, or evidence. Those who disagree with him, alas, are pretty smart and have pretty good arguments if you bother to read them. So, he tries to discredit them with personal attacks.

This is the political sphere, not the intellectual one. Don’t argue with them, swift-boat them. Find some embarrassing quote from an old interview. Well, good luck, Paul. Let’s just not pretend this has anything to do with economics, or actual truth about how the world works or could be made a better place.

Krugman backers, being the sane, rational people we all know them to be, are also given an instruction from Prof. Cochrane:

Krugman fans: Please don’t bother emailing me to tell me what a jerk I am.

Ahhhh..... the intellectual acumen of the Krugmanites. Can't you smell it?
