Inflation and Deflation
C.2 Inflation and Deflation
1. Influencing Factors
1.1 Inflation
- Demand-Pull Inflation: Occurs when aggregate demand exceeds aggregate supply.
- Example: Post-WWII recovery in the US (1945–1950)
- Cost-Push Inflation: Caused by increases in production costs (wages, raw materials).
- Example: Oil price shocks (1973, 1979)
- Built-In Inflation: Result of adaptive expectations and wage-price spirals.
- Example: Post-1970s US inflation
- Monetary Inflation: Increase in money supply leads to higher prices.
- Example: Hyperinflation in Zimbabwe (2008)
- Exchange Rate Fluctuations: Depreciation of currency increases import prices.
- Example: Indian Rupee depreciation (2013)
- Government Policies: Fiscal deficits and excessive money supply.
- Example: India’s fiscal deficit (2011–2012)
1.2 Deflation
- Demand-Side Deflation: Reduction in aggregate demand leads to falling prices.
- Example: Great Depression (1929–1933)
- Supply-Side Deflation: Increase in supply without demand growth.
- Example: Post-WWII Japan (1950s–1990s)
- Technological Advancements: Lower production costs and increased efficiency.
- Example: Industrial Revolution (18th–19th century)
- Globalization: Increased competition and lower prices.
- Example: China’s manufacturing boom (1980s onward)
- Monetary Contraction: Reduction in money supply.
- Example: US Great Depression (1930s)

3.2 Deflation
| Impact | Description | Example |
|---|---|---|
| Reduced Consumer Spending | People delay purchases, leading to lower demand. | Great Depression (1929–1933) |
