Can you show me a goldbug with a Nobel Prize in Economics and a column in a New York Times-class newspaper or other similar venue?
I know what you're saying, and it is literally true, I don't deny that. But Krugman should be held to a higher standard.
Personally, I find him very disappointing. A guy with a Nobel Prize in Economics ought to be making compelling arguments that are a surprise to me, and thus contain information in the information theoretic sense. (That's my favorite way of looking at information in an English context.) Instead, I can predict in advance what Krugman's position on a topic will be now with virtually 100% confidence, which should not be possible if he's actually writing with insight that someone of such stature should be bringing to topics, as I most assuredly hold a Nobel Prize in absolutely nothing. Even if he chooses doctrinaire liberal choices completely reliably, he should be able to defend them with far more interesting arguments than I actually see from him, the kind of interesting that even when you disagree you at least stop to think.
But yes, I am also disappointed in Krugman.
The debate being doctrinal seem to make the debate seem unimprotant especially when people don't know what it is about. The debate is about how to study the science of economics and the proper use of the scientific method. That's a pretty improtant debate that has been waging on for years.
Note: Edit to correct inaccuracy in the presentation of my comment's intention.
Although, it's easy to argue that neither is macroeconomics.
Maybe economics really has gone wrong in the past 40-80 years, and there's no salvageable content in all the research since then. But a lot of economists (particularly the behavioral school) are doing real empirical science lately, and I'd bet that they're likely to be onto something.
