The equation of exchange is a mathematical expression of the quantity theory of money. In its basic form, the equation says that the total amount of money that changes hands in an economy equals the total money value of goods that change hands, or that nominal spending equals nominal income.
What happens to velocity when money supply increases?
The Demand for Money and the Velocity of Money Are Inversely Related. An increased money supply will lower money velocity, while a decreased money supply will increase money velocity, all else being equal.
What is the formula for the quantity theory of money?
One of these rules is as follows: if you have two variables, x and y, then the growth rate of the product (x × y) is the sum of the growth rate of x and the growth rate of y. We can apply this to the quantity equation: money supply × velocity of money = price level × real GDP.
Why does increase in money supply increase inflation?
Increasing the money supply faster than the growth in real output will cause inflation. The reason is that there is more money chasing the same number of goods. Therefore, the increase in monetary demand causes firms to put up prices.
What is quantity theory of money in economics?
Definition: Quantity theory of money states that money supply and price level in an economy are in direct proportion to one another. When there is a change in the supply of money, there is a proportional change in the price level and vice-versa.
What is Dr Marshall’s exchange equation?
Marshall has explained the value of money through the. below mentioned equation: (Here, M : quantity of money, Y: monetary income, K: that part of the income which people want to. keep as cash) Because monetary income (Y) is the product of gross production (O) and price level (P), i.e., Y = PXO.
What is velocity of money supply?
Velocity is a ratio of nominal GDP to a measure of the money supply (M1 or M2). It can be thought of as the rate of turnover in the money supply–that is, the number of times one dollar is used to purchase final goods and services included in GDP.
What is the quantity equation?
Quick Reference. The equation MV = PT relating the price level and the quantity of money. Here M is the quantity of money, V is the velocity of circulation, P is the price level, and T is the volume of transactions. The quantity equation is the basis for the quantity theory of money.
