Fedophilia por George Selgin:
This veneration of the Fed has long struck me as perverse. Its record can hardly be said, after all, to supply grounds for complacency, much less for the belief that no other system could possibly do better ..
I’m convinced that imagination, or the lack of it, also plays a part. To some extent the problem is too much rather than too little imagination. With fiat money, and a discretionary central bank, it’s always theoretically possible to have the money stock (or some other nominal variable) behave just like it ought to, according to whichever macroeconomic theory or model one prefers. In other words, a modern central bank is always technically capable of doing the right thing, just as a chimpanzee jumping on a keyboard is technically capable of typing-out War and Peace. Just as obviously, any conceivable alternative to a discretionary central bank, whether based on competition and a commodity standard or frozen fiat base or on some other “automatic” mechanisms, is bound to be imperfect, judged relative to some—indeed any—theoretical ideal. Consequently, an economist need only imagine that a central bank might somehow be managed according to his or her own particular monetary policy ideals to reckon it worthwhile to try and nudge it in that direction, but not to consider other conceivable arrangements.
.. when most monetary economists talk about the virtues of this or that central bank, they’re mostly talking through their hats, because they haven’t a clue concerning what other institutions might be present, and what they might be up to, if the central bank wasn’t there.
Of course even the most vigorous deprogramming regimen is unlikely to alter the habits of hard-core Fed enthusiasts. But it might at the very least make them more inclined to engage in serious debate with the Fed’s critics, instead of allowing the Fed's apologists to go on believing that they answer those critics convincingly simply by rolling their eyes.
