The quantity equation itself as stated above is uncontroversial, as it amounts to an identity or, equivalently, simply a definition of velocity: From the equation, velocity can be defined residually as the ratio of nominal output to the stock of money: = /. Developing a theory out of the equation requires assumptions be made about the causal ...
The Cambridge equation first appeared in print in 1917 in Pigou's "Value of Money". [2] Keynes contributed to the theory with his 1923 A Tract on Monetary Reform.. The Cambridge version of the quantity theory led to both Keynes's attack on the quantity theory and the Monetarist revival of the theory. [3]
That is to say that, if and were constant or growing at equal fixed rates, then the inflation rate would exactly equal the growth rate of the money supply. An opponent of the quantity theory would not be bound to reject the equation of exchange, but could instead postulate offsetting responses (direct or indirect) of Q {\displaystyle Q} or of V ...
In macroeconomics, money supply (or money stock) refers to the total volume of money held by the public at a particular point in time. There are several ways to define "money", but standard measures usually include currency in circulation (i.e. physical cash ) and demand deposits (depositors' easily accessed assets on the books of financial ...
In monetary economics, the money multiplier is the ratio of the money supply to the monetary base (i.e. central bank money). If the money multiplier is stable, it implies that the central bank can control the money supply by determining the monetary base.

A social optimum occurs when the nominal rate is zero (or deflation is at a rate equal to the real interest rate), so that the marginal social benefit and marginal social cost of holding money are equalized at zero. Thus, the Friedman rule is designed to remove an inefficiency, and by doing so, raise the mean of output.
Monetary economics is the branch of economics that studies the different theories of money: it provides a framework for analyzing money and considers its functions ( as medium of exchange, store of value, and unit of account), and it considers how money can gain acceptance purely because of its convenience as a public good.
