Study Notes

Inflation is the increase in the overall level of prices over time in most modern economies.
Economists measure inflation rates using the percentage change in the Consumer Price Index (CPI) and the GDP deflator.
Deflation is a period when most prices fall, a phenomenon that occurred in the 19th century.
Hyperinflation is an extraordinarily high rate of inflation, as observed in Germany in 1923, Zimbabwe in 2008, and Venezuela in 2017, where average monthly price increases were very significant.
A classical theory of inflation assumes flexible prices and market clearing; it describes long-run economic behavior and is useful for understanding inflation in the short run, assuming short-run price stickiness is ignored.

The Quantity Theory of Money

The quantity of money in an economy is related to the number of dollars exchanged in transactions.
Money is held to buy goods and services, directly implying the more money needed for transactions, the more held.
The quantity equation is represented as: Money x Velocity = Price x Transactions (M x V = P x T)
T refers to the total number of transactions during a set time period (like a year); it signifies how many times goods/services are exchanged for money.
P represents the typical transaction price, or the number of dollars exchanged in a transaction.
M is the quantity of money.
V (Velocity) measures how quickly money moves through the economy. It indicates the number of times a dollar changes hands in a specific time period.
The quantity equation can be rewritten as (using Y instead of T to represent total output, representing transactions): M x V = P x Y

From Transactions to Income

The quantity equation is modified for practical measurement by using nominal GDP (Y) as a proxy for total transactions instead of T.
The modified equation is: V x M = P x Y, where Y represents the total output of the economy.

Money Demand and the Quantity Equation

Real money balances measure the purchasing power of the money supply (M/P).
A simple money demand function is written as (M/P)d = k * Y.
K represents the amount of money people wish to hold for each dollar of income in the respective economy (exogenous).
Real money balances desired are proportional to real income, in other words, the more income, the more money desired.
The Velocity of Money (V) and the money demand parameter (K) can be related as V=1/K.
The greater K, the lower V, less frequently money changes hands, and Vice-versa.

The Quantity Theory of Money (cont'd)

With constant velocity (V), the money supply determines nominal GDP.
Real GDP is determined by factors of production and the relevant production function.
The price level is calculated as Nominal GDP / Real GDP.
Assuming constant velocity, the quantity theory of money implies that the price level is proportional to the money supply.
Inflation rate is calculated by: π = (ΔM/M) − (ΔY/Y) where (△M/M) is the growth rate of money and (△Y/Y) is the growth rate of output.

Seigniorage

Seigniorage is the revenue raised from printing money by a government.
Inflation, which arises from increasing the money supply, is analogous to a tax on holding money
Countries with high money growth will likely have higher inflation rates in the long run.

Inflation and Interest Rates

Real interest rates are adjusted for inflation.
Nominal interest rate (i) = Real Interest rate (r) + Inflation rate (π)
The Fisher equation shows the relationship between the real interest rate, inflation rate, and nominal interest rate (i = r + π).

Money Demand and Nominal Interest Rates

In the quantity theory of money, the demand of real money balances depends only on real income (Y).
The nominal interest rate also impacts money demand.
The nominal interest rate is the opportunity cost of holding money rather than bonds.

Equilibrium

Equilibrium occurs when the supply of real money balances equals the demand for real money balances; M/P = L(i, Y)
The money supply (M) is determined exogenously by the Fed.
Real income (Y) is determined by the factors of production and technology.
Real interest rate (r) adjusts to ensure savings equals investment.
