==> Nick Rowe agrees with me that Steve Landsburg’s analysis of paying down government debt is only true if we assume perfect certainty. (Steve I think would totally agree, and that’s why I said in my original post that this was an argument over specifying assumptions for the reader, not about the implications of those assumptions.) Incidentally, if you have never seen Rowe in action, just skim the comments section, only reading his posts. You literally could learn a lot of economics just reading him patiently arguing with people. (In contrast, I am so sarcastic in my comments section that even my allies aren’t quite sure what my point is.) The other good thing about Nick is, he’s pretty humble. So you walk away thinking, “It’s not that this Canadian guy is all that smart, it’s just he’s been studying this stuff longer than I’ve been alive.”
==> Speaking of debt, I’m pleased to announce that for once, I agree with Daniel Kuehn on the government debt stuff! I don’t think Arnold Kling’s response to Krugman’s “we owe it to ourselves” position really got at the fundamental problem. To be clear, it’s not that Kling said anything wrong, and in fact he is highlighting one of the serious, real-world problems with deficit finance. But Krugman really did handle this type of thing by admitting upfront that government debt could have distributional implications for future generations. The stuff Kling is talking about doesn’t really show that Krugman is just flat out wrong for focusing on “we owe it to ourselves,” the way Buchanan/Boudreaux/Rowe did.
==> Poor Ron Paul gets ambushed at 13:30 by this host asking about the Murphy-Krugman Debate.
==> It’s kind of interesting: Someone in the comments of my post about Keynesians and consumption pointed to this Krugman article, where he definitely talks about the limitations of the “paradox of thrift” etc. But if I wanted to be a jerk, I would say, “So you prove to me that Keynesians don’t focus much on consumption, by pointing to Paul Krugman chiding Keynesians for focusing too much on consumption?” Anyway in the interest of holiday charity let me say that actual Keynesian economists are not quite the mindless champions of “consume consume consume!” that their critics sometimes attack, but there is no doubt that the caricature is based on a germ of truth: Even Krugman admits as much in the opening paragraphs of that linked article. So it’s not this right-wing myth the way Gene Callahan and Daniel Kuehn are suggesting.
