Question
For each shock identified below, shift the AD curve, the SRAS curve, or both to show its effects on aggregate demand and/or aggregate supply. Then move point E to the new short-run equilibrium to indicate the new price level \( P \) and output \( Y \). Assume the economy starts out in long-run equilibrium.

**a. An exogenous decrease in the velocity of money.**

**Graph Explanation:**

The graph depicts the intersection of three curves: 

1. **LRAS (Long-Run Aggregate Supply)**: A vertical green line indicating that output is independent of the price level in the long run.

2. **AD (Aggregate Demand)**: A downward-sloping blue line representing the relationship between the price level and the quantity of goods and services demanded.

3. **SRAS (Short-Run Aggregate Supply)**: An upward-sloping red line showing the relationship between the price level and the quantity of goods and services supplied in the short run.

- The initial equilibrium point \( E \) is where the AD, SRAS, and LRAS curves intersect. 

In response to an exogenous decrease in the velocity of money:

- The AD curve will shift to the left, indicating a decrease in aggregate demand.
- As a result, the new short-run equilibrium will be at a lower price level \( P \) and reduced output \( Y \).

This shift reflects the effects on the economy as it moves to a new equilibrium.
