The velocity of money provides another perspective on money demand.Given the nominal flow of transactions using money, if the interest rate on alternative financial assets is high, people will not want to hold much money relative to the quantity of their transactions—they try to exchange it fast for goods or other financial assets, and money is said to "burn a hole in their pocket" and ...
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 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 ...
This implies that the velocity of money must be predictable. In the 1970s velocity had seemed to increase at a fairly constant rate, but in the 1980s and 1990s velocity became highly unstable, experiencing unpredictable periods of increases and declines.
For example, the velocity of money is defined as nominal GDP / nominal money supply; it has units of (dollars / year) / dollars = 1/year. In discrete time , the change in a stock variable from one point in time to another point in time one time unit later (the first difference of the stock) is equal to the corresponding flow variable per unit ...
After the subsequent equations are substituted into the first three equations above, one has a system of three equations in three unknowns, two of which are GDP and the domestic interest rate. Under flexible exchange rates , the exchange rate is the third endogenous variable while BoP is set equal to zero.
Advanced Placement (AP) Macroeconomics (also known as AP Macro and AP Macroecon) is an Advanced Placement macroeconomics course for high school students that culminates in an exam offered by the College Board.
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.
