Costs of Inflation - AP Macroeconomics

A period of high inflation combined with stagnation in economic growth. Combines the worst aspects of inflation and economic recession simultaneously.

Creates uncertainty, potentially reducing long-term investments. Unpredictable future costs make long-term project planning more difficult.

Costs to firms of changing prices due to inflation. Named after restaurant menus that need frequent price updates during inflation.

Brackets may not adjust, leading to higher taxes on nominal gains. Taxpayers pushed into higher brackets despite no real income increase.

Interest rates often rise to compensate for lost purchasing power. Lenders demand higher rates to maintain real returns during inflationary periods.

Decreases real value of money saved if interest rates are low. Real return becomes negative when nominal interest rate falls below inflation rate.

The loss of purchasing power due to inflation, acting like a tax. Government essentially collects revenue as money's value erodes over time.

Reduces real income as fixed payments lose purchasing power. Pensions, wages, and benefits often don't adjust immediately to rising prices.

Inflation that occurs unexpectedly, affecting contracts and plans. Creates greater economic disruption as contracts weren't designed for price changes.

Inflation that is expected and planned for by economic agents. Allows businesses and consumers to adjust contracts and wages accordingly.

Borrowers gain as the real value of repayments decreases. They pay back loans with money that has less purchasing power than borrowed.

Lenders lose as the real value of repayments decreases. Fixed loan payments become worth less in real terms when inflation rises.

Costs incurred from reducing money holdings during inflation. People make more frequent trips to banks/ATMs as cash loses value quickly.

A general increase in prices and fall in purchasing power. This fundamental definition captures inflation's dual impact on prices and purchasing power.

Real interest rate = nominal rate - inflation rate. Real rate measures actual purchasing power return after inflation adjustment.

Can reduce competitiveness if domestic prices rise faster than global prices. Higher domestic costs make exports more expensive relative to foreign competitors.

Creates uncertainty, potentially reducing long-term investments. Unpredictable future costs make long-term project planning more difficult.

A decrease in the general price level of goods and services. Opposite of inflation, where general price levels fall over time.

May lead to increased spending to avoid future price rises. Consumers may accelerate purchases expecting continued price increases.

Illustrates an inverse relationship between inflation and unemployment. Shows short-run tradeoff between unemployment and inflation rates.

Describes the relationship between nominal interest rates and inflation. Nominal rates tend to rise one-for-one with expected inflation.

Can worsen inequality if wages do not keep pace with price increases. Fixed-income earners suffer most while asset owners may benefit.

Consumer Price Index (CPI). Tracks price changes in a representative basket of consumer goods.

Inflation measure excluding volatile food and energy prices. Provides more stable measure by removing temporary price fluctuations.

Erodes purchasing power if pensions are not inflation-indexed. Fixed pensions lose real value unless adjusted for price level changes.

An extremely high and typically accelerating inflation rate. Often exceeds 50% monthly, can destroy economies and currencies completely.

Interest rate adjusted for inflation. Nominal rate minus inflation rate, showing true purchasing power return.

Adjusting the interest rate. Higher rates reduce money supply and cool inflationary pressures.

Inflation driven by increased aggregate demand. Excess demand in economy drives prices upward across multiple sectors.
