3.2 Inflation and Its Impact on the Economy

This lesson explores inflation and its effects, including how it’s measured using the Consumer Price Index (CPI) and Producer Price Index (PPI). We will examine demand-pull, cost-push, and built-in inflation, along with its impact on purchasing power, interest rates, and savings. Extreme cases like hyperinflation and deflation, including Zimbabwe’s crisis, will also be discussed.

Inflation is defined as the sustained increase in the general price level of goods and services in an economy over a period of time. It is typically measured using indices such as the Consumer Price Index (CPI) and the Producer Price Index (PPI), which track changes in the prices of a selected basket of goods and services. Understanding inflation is crucial as it directly influences purchasing power, economic stability, and overall economic growth.

There are several types of inflation, each with distinct causes and effects.

• Demand-Pull Inflation: Demand-pull inflation occurs when the overall demand for goods and services exceeds supply, driving prices up. This typically happens during periods of economic growth when consumer and business confidence are high, leading to increased spending.
• Cost-Push Inflation: Cost-push inflation arises when the costs of production increase, forcing producers to raise prices to maintain their profit margins. This can be driven by factors such as higher wages, rising raw material costs, or supply chain disruptions.
• Built-In Inflation: Built-in inflation, or wage-price inflation, occurs when businesses raise prices to offset rising wages, creating a feedback loop where higher wages lead to higher prices and vice versa.
