Inflation is the rise in the general price level of goods and services over time. Think of it as a balloon that keeps inflating when you keep blowing air into it. If the balloon (price level) gets too big, it can burst (economic instability).
High inflation erodes purchasing power, creates uncertainty, and can lead to a wage‑price spiral. Keeping inflation low and stable helps businesses plan, encourages savings, and supports long‑term growth.
Monetary Policy (Central Bank Actions)
📈 Analogy: Raising interest rates is like turning down the faucet – less water (money) flows into the economy.
Fiscal Policy (Government Actions)
💰 Example: The UK government may increase VAT to cool down a hot economy.
Supply‑Side Measures
🚀 Analogy: Think of supply‑side policies as upgrading the engine of a car – it runs smoother and faster.
| Policy Tool | Short‑Term Effect | Long‑Term Effect | Key Caveat |
|---|---|---|---|
| ↑ Interest Rates | ↓ Demand, ↑ Savings | Stabilises expectations, encourages investment | Can slow growth if too high |
| ↑ Taxes | ↓ Disposable income, ↓ Consumption | Reduces fiscal deficit, improves confidence | May reduce equity if too steep |
| Supply‑Side Reforms | Minimal immediate impact on price level | Long‑term price stability via higher output | Requires time and investment |
The Phillips Curve shows an inverse relationship between unemployment and inflation in the short run. However, if people expect higher inflation, the curve shifts right, making inflation harder to control.
📊 Key point: Credibility of the central bank is crucial – if people trust that the bank will keep inflation low, expectations stay anchored.
Remember to:
💡 Tip: Practice diagramming the Phillips Curve and labeling the shift due to expectations.
Keep these points in mind, and you'll be ready to tackle any exam question on inflation‑reducing policies! 🚀
