# Economics Masterclass: The Top 5 Macro Diagrams You MUST Know for Paper 4

If you're sitting the CIE 9708 Paper 4 exam, there is one universal truth: you cannot score above a C without accurate diagrams.

The examiners explicitly state in the mark scheme that diagram accuracy is worth up to 4 marks per essay. That's the difference between a B and an A*. Yet most students either skip the diagram entirely, or draw something so vague that it earns zero marks.

In this masterclass, we break down the 5 most important macro diagrams that appear in virtually every Paper 4 sitting, and explain exactly what the examiner wants to see on each one.

1. 📈 The AD/AS Model (Demand-Pull Inflation)

This is the single most important diagram in macroeconomics. It appears in questions about inflation, fiscal policy, monetary policy, supply-side policy, and economic growth.

What you must show: * A clearly labeled Price Level (PL) on the Y-axis and Real GDP (Y) on the X-axis. * A downward-sloping Aggregate Demand (AD) curve. * An upward-sloping Short-Run Aggregate Supply (SRAS) curve. * A vertical Long-Run Aggregate Supply (LRAS) curve at full employment output (Yf). * The shift: AD1 → AD2 (rightward), with arrows showing the movement from P1 to P2.

Common mistake: Drawing AD as a straight line. The examiner prefers a smooth curve that shows diminishing responsiveness at higher price levels.

2. 📉 The AD/AS Model (Cost-Push Inflation)

This is the mirror image of Diagram 1, but students consistently confuse the two.

What you must show: * SRAS shifting leftward (SRAS1 → SRAS2), NOT AD shifting. * The result: Price level rises (P1 → P2) AND output falls (Y1 → Y2). * This is the key difference — cost-push inflation causes stagflation (higher prices + lower output), while demand-pull inflation typically increases output.

Common mistake: Shifting AD instead of SRAS. This immediately tells the examiner you don't understand the difference.

3. 🔄 The Keynesian AS Curve

For questions about unemployment, the liquidity trap, or fiscal policy effectiveness, the Keynesian AS curve is essential.

What you must show: * A horizontal section (spare capacity / mass unemployment). * An upward-sloping section (approaching full employment). * A vertical section (full employment — classical range). * AD shifting rightward in the horizontal section increases output with NO inflation — this is the Keynesian justification for fiscal stimulus.

4. 💱 The Exchange Rate Diagram

This appears in every single Paper 4 question about trade, the balance of payments, or monetary policy in an open economy.

What you must show: * Exchange Rate on the Y-axis, Quantity of Currency on the X-axis. * Downward-sloping Demand for currency curve. * Upward-sloping Supply of currency curve. * The shift (e.g., Supply shifting right → depreciation, or Demand shifting right → appreciation).

---

5. 📊 The Phillips Curve

This is the secret weapon for evaluation paragraphs. Almost no students use it, but the examiners love it.

What you must show: * Inflation Rate on the Y-axis, Unemployment Rate on the X-axis. * The short-run Phillips Curve showing the trade-off. * The long-run vertical Phillips Curve at the Natural Rate of Unemployment (NRU). * Explain why the trade-off breaks down in the long run (adaptive expectations).
