Monetary Growth and Inflation - AP Macroeconomics

Unexpected inflation benefits borrowers. They repay loans with money worth less than when borrowed.

$i = r + \text{expected inflation}$. Shows how nominal rates adjust for expected price changes.

Expansionary policy increases inflation. Increasing money supply stimulates demand and raises prices.

Cost-push inflation. Supply-side inflation from higher input costs or wages.

Monetary growth does not affect long-term output. Money is neutral in the long run for real variables.

Facilitates relative price adjustments. Helps economies adjust to changing supply and demand conditions.

Hyperinflation drastically reduces currency value. Money becomes nearly worthless as a store of value.

Monetarism. School of thought emphasizing money supply control for price stability.

Distortion of relative prices. Makes it harder for markets to allocate resources efficiently.

To adjust payments for inflation effects. Protects against inflation by automatically adjusting payments.

Change in consumption due to change in purchasing power of money. Higher prices reduce the real value of cash holdings.

Inflation decreases purchasing power. Each dollar buys fewer goods and services over time.

Nominal rates rise with expected inflation. One-for-one relationship between inflation expectations and nominal rates.

Unexpected inflation harms lenders. They receive back money with less purchasing power than they lent.

Real interest rate = Nominal interest rate - Inflation rate. Adjusts nominal rates for the effect of inflation.

$M$ represents the money supply. The total amount of money circulating in the economy.

$P$ is the price level. The average level of prices for goods and services.

An increase in $M$ leads to higher inflation. More money chasing the same goods drives up prices.

$Y$ is the real output or real GDP. Measures economic output adjusted for inflation.

A decrease in the general price level of goods and services. Opposite of inflation; prices fall across the economy.

Hyperinflation is extremely high and typically accelerating inflation. Usually exceeds 50% monthly and destroys economic stability.

Shoe leather costs. Time and effort spent making frequent bank transactions.

The price level doubles. Direct proportional relationship from the quantity equation.

Monetary policy. Includes open market operations, reserve requirements, and discount rates.

Menu costs. Businesses incur costs to update prices, catalogs, and systems.

$V$ is the velocity of money. Measures how frequently money changes hands in transactions.

$MV = PY$. Represents the relationship between money supply, velocity, prices, and output.

Monetary inflation is an increase in the money supply. Different from price inflation, which is rising prices.

Real interest rate = Nominal interest rate - Inflation rate. Adjusts nominal rates for the effect of inflation.
