**Chapter 20: Causes of Economic Fluctuations**

**Assumption:**
- The economy begins in long-run equilibrium.

**Long-run Equilibrium:**
- Natural level of output = Q1
- Expected price level = Actual price level = P1
- Aggregate Demand (AD) and Short-Run Aggregate Supply (SRAS) fluctuations must return to the long-run equilibrium aggregate supply (LRAS)

**Graph Explanation:**
- The graph on the right depicts three key curves: Aggregate Demand (AD1), Short-Run Aggregate Supply (SRAS1), and Long-Run Aggregate Supply (LRAS).
- The vertical LRAS line indicates the natural level of output (Q1), which is the potential output of the economy when resources are fully utilized.
- The intersection of AD1 and SRAS1 at point (Q1, P1) demonstrates the expected and actual price level (P1), where the economy is in long-run equilibrium.
- The diagram illustrates how fluctuations in AD and SRAS impact the economy's movement back to the long-run equilibrium point.
