This isn’t an interesting question. It is not even a debate, as such, because all of the most relevant economic issues have already been resolved. So I’ll just repeat what I said about the gold standard in the other thread, with some slight editing for clarity:
The gold standard is a stupid stupid stupid system. We dig a yellow metal out of a cave in the ground. We then build another, artificial cave in a place called a “bank”. We then move the little yellow pieces of metal from one cave to the other. But that’s a key point. The gold is never truly “free” to be bought and sold in the market. It stays in its new cave, which raises the question: Why did we even dig it out of the first cave anyway? We then print pieces of paper, and promise that we will supply the yellow metal out of our new man-made cave for anyone who has our pieces of paper. But the system only works, see, if no one generally wants to take the metal. A person here or there is free to take their gold, sure. But if everyone would rather have the yellow metal than the paper, then the standard collapses. So in order for it to work, we must have that metal in the artificial cave be in such a way that it stays, perpetually, in that artificial cave. Doing nothing. If it were taken out of that cave, after all, it wouldn’t work. We’d just have gold currency, not a gold standard. And then we’d be left with all the problems of having gold currency, namely, that carrying around that much gold is a gigantic pain in the ass. So the yellow metal must sit in its new cave, gathering dust. Forever. That’s a functioning gold standard. I don’t want to discount the idea of a currency peg in all situations. It can work in some contexts. But reliance on the gold standard, for its own sake, is just dumb. It makes no bloody sense at all.
The Fed needs to “print money” in emergencies. Among professional economists, there are numerous topics of genuine disagreement. This is not one of those topics. If you take away the ability to expand the money supply at will, then you are dooming us to continually repeat the mistakes that caused the Great Depression. This is the view of everyone from hardcore libertarians like Milton Friedman to noted liberal economists like Paul Krugman. To deny this is to deny all of our modern economic theory and history.
Now here’s the actual interesting part: It is reasonable to believe that the Fed should not act on their own discretion when printing money, but rather work within clearly established guidelines and rules, e.g. 5% annual nominal GDP growth.
The Federal Reserve is, indeed, a monstrously power institution. And it is perfectly reasonable for people to want to come up with methods to ensure that the Fed does not abuse its powers. One of these questions is the real classic, best formulated by the libertarian economist Milton Friedman, of discretion vs. rules. Discretion is giving the Fed leeway to operate based on their own readings of the situation. Friedman, as a libertarian who wanted to curb the power of government, did not favor discretion. He wanted the Fed to follow specific guidelines, predictable rules that everyone in the market could rely on. So which is better? Well, I’d say the libertarians like Friedman have a point. I’d say that a rules-based system of monetary policy can be generally better, depending on the specific rule chosen. Friedman’s original rule, for example, was wrong. It would not work. And that’s the real kicker, isn’t it? If you’re stick with the wrong rule at the wrong time, then you can end up with a monetary policy that exacerbates the problems your economy is currently facing instead of fixing those problems. So yeah, I do think a rules-based system is better, but I also believe that we must absolutely be certain to choose the right monetary rule.
And I think the right monetary rule is likely to be nominal GDP targeting, although I do not know for sure.
What’s interesting about this rule is that, even though the Federal Reserve has “printed” enough money to more than double the monetary base to fight this current downturn, (seriously, check this shit out), printing that money still was not enough. If you use nominal GDP targeting as a rule, then the Fed’s actions lately have been insufficiently aggressive. Which is a good way of putting into perspective how seriously our money supply had been damaged by the financial crisis. We suffered our biggest drop in nominal GDP since the Great Depression, and according to this rule, the Fed should’ve taken even strong measures to fight that drop in NGDP, to ensure that we reached our target of a 5% increase.
