Which of the following statements is/are true about the diagrams above depicting the macroeconomy in both Keynesian and Classical frameworks and a change from AEo to AE* and ADo to AD*? O(a) The left-hand diagrams show the effect of an increase in Aggregate Expenditures (and Aggregate Demand), where the short-run Aggregate Supply is horizontal, meaning a constant products price level. (b) The right hand diagrams show the effect of an increase in Aggregate Expenditures (and Aggregate Demand), where short-run Aggregate Supply is vertical (constant Aggregate Quantity Supplied). O(c) The left-hand diagrams illustrate the Keynesian range of the short-run Aggregate Supply curve, where Keynesian expansionary policy does not cause any inflation and thus is very effective. O (d) The right-hand diagrams illustrate the Classical or Monetarist range of the short-run Aggregate Supply curve, where Keynesian expansionary policy is totally dissipated in inflation and thus is totally ineffective. O(e) All the above

### Question 15 Analysis

#### Diagram Explanation

**Top Left Graph**:
- **Title**: Expenditures, Income vs. Real GDP (Q)
- **Axes**: 
  - Vertical Axis: Expenditures, Income (ranging from 0 to 60)
  - Horizontal Axis: Real GDP = Q (ranging from 0 to 50)
- **Lines**:
  - Black Line: Q
  - Red Lines: 
    - Lower Line: \( AE_0 \)
    - Upper Line: \( AE^* \)
- **Key Feature**: The two red lines indicate a shift in Aggregate Expenditures.

**Top Right Graph**:
- **Title**: Expenditures, Income vs. Real GDP (Q)
- **Axes**: 
  - Vertical Axis: Expenditures, Income (ranging from 0 to 60)
  - Horizontal Axis: Real GDP = Q (ranging from 0 to 50)
- **Lines**:
  - Same as above with the lines \( AE_0 \) and \( AE^* \) showing a shift.

**Bottom Left Graph**:
- **Title**: Price Level vs. Real GDP (Q)
- **Axes**:
  - Vertical Axis: Price Level (ranging from 0 to 80)
  - Horizontal Axis: Real GDP = Q (ranging from 0 to 50)
- **Lines**:
  - Blue Line: AS (Aggregate Supply)
  - Magenta Lines:
    - Lower Line: \( AD_0 \) (Initial Aggregate Demand)
    - Upper Line: \( AD^* \) (New Aggregate Demand)
- **Key Feature**: This illustrates a shift in Aggregate Demand.

**Bottom Right Graph**:
- **Title**: Price Level vs. Real GDP (Q)
- **Axes**:
  - Vertical Axis: Price Level (ranging from 0 to 80)
  - Horizontal Axis: Real GDP = Q (ranging from 0 to 50)
- **Lines**:
  - Blue Line: AS (Aggregate Supply)
  - Magenta Lines:
    - Lower Line: \( AD_0 \) 
    - Upper Line: \( AD^* \)
- **Key Feature**: Similar shift in Aggregate Demand as seen in the previous graph.
