If there is one concept that illustrates the difference between a top-down macro-economic approach and the reality of everyday life it is the velocity of circulation of money. Compare the following statements:
“The collapse in velocity is testament to the substantial misallocation of capital brought about by the easy money regimes of the past 20 years.” Broker’s research note; and
“The mathematical economists refuse to start from the various individuals’ demand for and supply of money. They introduce instead the spurious notion of velocity of circulation according to the pattern of mechanics.” Ludwig von Mises, Human Action.
