Bad Tayloring: Since they aren’t currently able to demand a return to the gold standard — and maybe a ban on paper money? — Republicans are pushing to mandate that the Fed follow the so-called Taylor rule, which relates short-term interest rates to unemployment (and/or the output gap) and inflation. John Taylor, not surprisingly, likes this idea. But it’s a really terrible idea, and not just for the reasons Tony Yates describes. ...
The world has turned out to be a much more dangerous place than Taylor-rule enthusiasts imagined, so why impose a rule devised, we know now, by economists who completely misjudged the risks?
Now Taylor himself has an excuse and rationale: he claims that the whole financial crisis thing was because the Fed departed slightly from his version of the rule in the pre-crisis 2000s. But as Yates points out, this assigns an importance to monetary policy that is wildly at odds with the kind of modeling used to justify the rule in the first place. It also, as Yates does not point out, has the distinct whiff of someone inventing ever-more bizarre stories to avoid admitting having been wrong about something. This is not the kind of argument on which to base rules that permanently constrain policy.
