This is the central contents of the money multiplier theory, and + / / + / is the money multiplier, [1] [2] a multiplier being a factor that measures how much an endogenous variable (in this case, the money supply) changes in response to a change in some exogenous variable (in this case, the money base).
In some economics textbooks, the supply-demand equilibrium in the markets for money and reserves is represented by a simple so-called money multiplier relationship between the monetary base of the central bank and the resulting money supply including commercial bank deposits. This is a short-hand simplification which disregards several other ...
In monetary economics, the equation of exchange is the relation: = where, for a given period, is the total money supply in circulation on average in an economy. is the velocity of money, that is the average frequency with which a unit of money is spent.
The multiplier may vary across countries, and will also vary depending on what measures of money are being considered. For example, consider M2 as a measure of the U.S. money supply, and M0 as a measure of the U.S. monetary base. If a $1 increase in M0 by the Federal Reserve causes M2 to increase by $10, then the money multiplier is 10.
Theories of endogenous money date to the 19th century, with the work of Knut Wicksell, [1] and later Joseph Schumpeter. [2] Early versions of this theory appear in Adam Smith's 1776 book The Wealth of Nations. [3] With the existence of credit money, Wicksell argued, two interest rates prevail: the "natural" rate and the "money" rate. The ...
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 ...
Money supply is determined by central bank decisions and willingness of commercial banks to loan money. Money supply in effect is perfectly inelastic with respect to nominal interest rates. Thus the money supply function is represented as a vertical line – money supply is a constant, independent of the interest rate, GDP, and other factors.
The effect of a change in the quantity of money is considered at p. 298. The change is effected in the first place in money units. According to Keynes's account on p. 295, wages will not change if there is any unemployment, with the result that the money supply will change to the same extent in wage units.
