Although Austrian theory of Money is the most advanced theory that is, I think it still has some flaws, and I want to discuss this. I sometimes get into arguments on the blog posts, but a forum I think is more suitable.
First, I think there is a problem with defining money as a good and thşs causes many problems down the road.
I think money is not a good. On the contrary, money is function that directly competes with “good function” that may or may not be inherent in things.
When you define an economics good, we can say it satisfies directly, or indirectly an specific human need and since needs are endless the more of the thing that contains “good function” the better it is. Consequently we can say that things with good functions represent wealth.
Money on the other hand is very different. As it is pointed out by many Austrian economists, the increase in money does not serve a social benefit and money is not wealth does not add to wealth, but only represent real wealth that is compromised of things that contain good functions like all the goods and services.
Mises was aware of this, and besides producer goods and consumer goods, he had to invent another category of good. But money is so different than goods, it causes many problems to categorize money as a type of good.
It think this mistake was due to the knowledge that money functions had inherent ties to the good function. Mises knew this but didn’t identify it clearly. Mises knew, according to the regression theorem, money couldn’t be enforced upon the market by an authority but had to come to being as a result of the market action. Or as Hayek would say, money was the result of human action but not design.
This is true but has to be formulated differently.
A thing can not gain money function, if it doesn’t first has a good function. But when it starts gaining money function it feeds on itself until good function is squeezed out, although not completely. Or in other words, when something begins gaining money functions, it starts losing its good function relative to before.
Money function, if we need to define it, is liquidity function, or medium of exchange. Or a function that facilitates indirect exchange.
Also one more thing to point out is the money function is a subjective function on an individual level. A thing has “money function” if the individual thinks it has money function.
The same physical thing may have money function according to one, and a good function according to another.
What does this all mean?
Firstly it means it is futile to try to measure money supply. Unless you can read the minds of billions of people at the same time you can not even get close to measuring it. İt means people will have to invent dubious concepts as velocity of money to cover the shortfall of their ignorance, and people who think money supply can be manageable will be around for ever.
Take cigarettes. In prison camps we know cigarettes gained money functions, or they began functioning as money. But how do you measure the money supply in this case. According to the conventional method, and according to Rothbard for that matter, you should count all the cigarettes in existence in the prison. But is this accurate? What if a prisoner that has 5 cigarettes is at one moment thinking of smoking one of the cigarettes, viewing one cigarette as a good, and using the rest as money? In that case even before the prisoner starts smoking that cigarette, the money supply had shrunk. And a the same moment, another who thought of smoking one cigarette changed his mind and decided he wants to use it as money. Then again the money supply changes.
Also in the case of hoarding. If someone decides to hoard some money, bury it somewhere and forget about it, how can that be a part of the money supply where there is no chance of it chasing any goods unless the hoarder changes his mind about it later.
The same problems arise in fiat money also. All these M’s can not really tell us anything because they all view the money supply as an aggregate figure that is detached from personal subjective choice.
Lets take the issue of time deposits. Are time deposits, or savings accounts, part of the money supply? No one can say in general. If one person thinks he can access his money any time, by paying a small penalty, then that is part of the money supply. But if one thinks otherwise then it isn’t . And what if they changed their minds just one moment?
This issue can not be dealt with only “demand to hold money” either.
Today banks in America have excess reserves of close to 1 trillion dollars. These are called excess reserves because banks choose to hoard them. Thus this money is not a part of the money supply and as we can see they do not cause any rise in general prices. You may say , their demand to hold money increased to offset the supply but If the same banks decided that they would start lending the money, even before they do so the supply of money would change dramatically, because they would act differently, the general prices would start moving. As of now the banks do not see these reserves as a medium of exchange. Those bank notes or entries on a ledger do not contain money functions. They are only an insurance against bankruptcy.
The same relates to gold prices. The biggest hoarders of gold are CB’s. By hoarding the gold they decrease the gold supply. And when they announce a sale, the gold supply increases pushing the price down, although no new gold was created. The same is true by other hoarders.
Take the ETF called GLD. Demand for GLD is not demand for money, since gold as of now is not a medium of exchange. It is not a demand for a interest or profit bearing investment. It is only a vehicle for hoarding. The increase in the amount of the gold that GLD is actually a decrease in the supply of gold.
Lets say gold becomes money again. This time hoarding it would become mostly pointless. Of course there would still be hoarders, not wanting to risk their savings by lending them out and since gold would keep its purchasing power people would hoard it much more than they hoard fiat currency. But never the less hoarding would decrease dramatically. But this time demand to hold gold would increase much more, because everyone would now want to hold gold as cash for their routine lives, instead of a handful of hoarders. Today 6 billions of people hold some kind of fiat money and very few hoard gold. When this fiat money system breaks down and gold becomes money again, this gold would stop being hoarded by few, and held by many as cash.
