Quantity Theory of Money
Quantity Theory of Money
The idea that changes in the money supply directly influence the price level, assuming that the velocity of money and the real output are relatively stable.
Velocity of Money
Velocity of Money
The number of times a unit of currency is used in transactions within a specific period.
Equation of Exchange
Equation of Exchange
The equation that describes the relationship between money supply (M), velocity of money (V), price level (P) and real output (Y): M × V = P × Y

Study Notes
Quantity Theory of Money
- The quantity theory of money examines the relationship between the money supply and inflation.
- Equation of Exchange: M × V = P × Y
- M = Money Supply
- V = Velocity of Money (Average number of times a dollar is spent per year)
- P = Price Level
- Y = Aggregate Output (Income)
- Velocity: Generally assumed to be fairly constant in the short run.
- Aggregate Output: Assumed to be at a full-employment level.
- Changes in money supply: Primarily affect the price level.
- Quantity Theory of Money: Nominal income (spending) is determined solely by the quantity of money.
- P × Y = M × V
Demand for Money
- Demand for money is influenced by the equation of exchange. To understand this in terms of demand, we divide both sides of the equation by V.
- M/V = P x Y
- Equilibrium in Money Market: When the money market is in equilibrium, the money supply (M) equals the money demand (Md).
- Md = k × P × Y
- k represents a constant
- The money demand is independent of interest rates. The level of transaction (determined by a constant PY level) directly correlates with the quantity of demanded money (Md).
- Md = k × P × Y
Quantity Theory and Inflation
- Percentage Change in (x × y) = (Percentage Change in x) + (Percentage change in y)
- Applying this to the equation of exchange, we get: %ΔM + %ΔV = %ΔP + %ΔY
- Inflation Rate (Ï€): The growth rate of the price level
- π = %ΔP
- Constant Velocity: Assuming a constant velocity (V), its growth rate is zero: %∆V = 0
- Simplified Quantity Theory: Simplifying the inflation equation using the assumption of a constant velocity, we have: π = %ΔM – %ΔY
- Changes in the money supply directly correlate with changes in the price level (inflation) when the velocity of money and aggregate output remain constant.
