Sep 11, 2025

Overview

This lesson introduces the concept of inflation, its definitions, types, related economic terms, and includes example scenarios to clarify concepts.

Definition and Nature of Inflation

  • Inflation is a continuous and considerable rise in the general price level of goods and services over time.
  • Inflation is not a once-off event but a sustained increase in prices.
  • It affects the purchasing power of money, meaning money buys fewer goods over time.
  • Inflation is typically measured as an annual percentage rate.

Types of Inflation

  • Demand-Pull Inflation occurs when demand for goods exceeds supply, often due to increased spending by consumers, businesses, or government.
  • This type is described as "too much money chasing too few goods."
  • Cost-Push Inflation happens when production costs (like labor or materials) rise significantly, leading producers to increase prices.

Related Economic Terms

  • Hyperinflation is an extremely rapid and out of control inflation, exceeding 50% per month or 100% over three years.
  • Stagflation is when high inflation and high unemployment occur together, making it difficult for governments to address both issues.
  • Deflation is a continual decrease in the general price level, where the inflation rate falls below 0%.
  • Disinflation refers to a fall in the rate of inflation (prices still rise, but more slowly).
  • Reflation is stimulating the economy to increase the price level back up to the long-term trend after a downturn.
