The quantity theory of money (often abbreviated QTM) is a hypothesis within monetary economics which states that the general price level of goods and services is directly proportional to the amount of money in circulation (i.e., the money supply), and that the causality runs from money to prices. This implies that the theory potentially ...
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 or of to /.
The Cambridge equation formally represents the Cambridge cash-balance theory, an alternative approach to the classical quantity theory of money. Both quantity theories, Cambridge and classical, attempt to express a relationship among the amount of goods produced , the price level , amounts of money, and how money moves.
There is some empirical evidence of a direct relationship between the growth of the money supply and long-term price inflation, at least for rapid increases in the amount of money in the economy. [53] The quantity theory was a cornerstone for the monetarists and in particular Milton Friedman, who together with Anna Schwartz in 1963 in a ...
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.

In the quantity theory of money, this is expressed as MV = PY, where money supply times velocity equals price times output. Lucas then introduced variation in the price level. This can occur through changes in the local price level of individual islands due to increased or decreased demand (i.e. asymmetric preferences, z) or through stochastic ...
