I’m still not sure how an entrepreneur would factor these changes in the supply of money in. It’s easy to present it as a solution, but the fallacy is uncovered when you find out there is no appreciable way for entrepreneurs to really know (besides the fact that entrepreneurs are not economists). If an entrepreneur wants to invest he will base his decision on what seems to him a juxtaposition between benefits and costs. Low interest rates make higher order production seem more beneficial. What is the entrepreneur to do in the case of artificial interest rates? Cease investment for the length of the boom? That can be many, many years. I think the lack of sensibility in this objection to the Austrian Business Cycle Theory is quite obvious.
What does velocity of money have to do with the supply of money? Money, or tangible assets used as a common good for trade, can only increase if the volume of these “tangible assets” increases. If the velocity of a particular piece of money increases it does not multiply into more money, it remains the same. Besides, the concept of velocity of money has already been refuted:
According to popular thinking, the idea of velocity is straightforward. It is held that over any interval of time, such as a year, a given amount of money can be used again and again to finance people’s purchases of goods and services. The money one person spends for goods and services at any given moment can be used later by the recipient of that money to purchase yet other goods and services.
From the equation of exchange, it seems that money together with velocity is the source of funding for economic activities. Furthermore, from the equation of exchange, it would appear that for a given stock of money, an increase in velocity helps finance a greater value of transactions than money could have done by itself.
As logical as it sounds, neither money nor velocity has anything to do with financing transactions. Here is why.
Consider the following: baker John sold ten loaves of bread to tomato farmer George for $10. Now, John exchanges the $10 to buy 5kg of potatoes from Bob the potato farmer. How did John pay for potatoes? He paid with the bread he produced.
Observe that John the baker had financed the purchase of potatoes, not with money, but with bread. He paid for potatoes with his bread, using money to facilitate the exchange. In other words, money fulfills here the role of the medium of exchange and not the means of payment.
The number of times money changed hands has no relevance whatsoever on the baker’s capability to fund the purchase of potatoes. What matters here is that he possesses bread that can be exchanged by means of money for potatoes.
How is it that the fact that the same $10 bill used in several transactions can add anything to the means of funding? By what means does the speed of money circulation add to the real pool of funding? Imagine that money and velocity would have indeed been means of funding or means of payments. If this was so, then poverty worldwide could have been erased a long time ago. Moreover, since rising velocity is supposed to boost effective funding, then it would have been to everyone’s benefit to make sure that money circulates as fast as possible. This implies that anyone who holds on to money should be classified as a menace to society, for he slows down the velocity of money and hence the creation of real wealth.
Austrian arguments against the mechanistic equation for velocity of money have been provided as early as Ludwig von Mises and Benjamin Anderson (who published his refutation as early as 1917).
