Question
The image is divided into two panels, titled "Figure 9.2."

**Panel a: The Industry**

- **Axes:** The vertical axis represents "Price per bushel ($)" and the horizontal axis represents "Bushels of wheat."
- **Curves:**
  - The supply curve is labeled "S" and slopes upwards.
  - Two demand curves are shown, labeled "D1" and "D2," both sloping downwards. "D1" is positioned to the left of "D2."
- **Equilibrium Points:**
  - The intersection of "S" and "D1" occurs at a price of $5 per bushel.
  - The intersection of "S" and "D2" occurs at a higher price, $7 per bushel.
  - An additional line indicates a price level of $9.

**Panel b: A Representative Firm**

- **Axes:** The vertical axis remains "Price per bushel ($)," and the horizontal axis indicates "Bushels of wheat."
- **Curves:**
  - "MC" represents the marginal cost curve, which intersects both the average total cost curve ("ATC") and the average variable cost curve ("AVC").
- **Equilibrium Point:**
  - Vertical dashed lines indicate quantities corresponding to different price levels:
    - At a price of $5, around 10 bushels are produced.
    - At a price of $7, around 12 or 13 bushels are produced.
    - At a price of $9, around 15 bushels are produced.

This illustration is a classic economic model depicting supply, demand, and cost structures within an industry and a representative firm, commonly used to show market equilibrium concepts and firm-level production decisions.

## Analysis of Wheat Market Dynamics

Figure 9.2 provides a detailed examination of the wheat market through two graphs.

### Graph (a): The Industry

- **Axes**: The vertical axis represents the price per bushel (\$), while the horizontal axis measures the quantity of bushels of wheat.
  
- **Supply and Demand**: 
  - The supply curve is labeled \( S \).
  - There are three demand curves labeled \( D_1 \), \( D_2 \), and \( D_3 \), each indicating different levels of demand.

- **Price Levels**: 
  - At \( D_1 \), the price is approximately \$5 per bushel.
  - \( D_2 \) intersects supply at around \$7.
  - \( D_3 \) intersects at \$9, indicating higher demand and price.

### Graph (b): A Representative Firm

- **Axes**: Similar to graph (a), the vertical axis shows the price, while the horizontal axis represents bushels of wheat.
  
- **Cost Curves**:
  - \( MC \): Marginal Cost
  - \( ATC \): Average Total Cost
  - \( AVC \): Average Variable Cost

- **Intersection Points**:
  - The MC curve intersects the ATC curve at the minimum point of the ATC.
  - Price lines at \$5, \$7, and \$9 are indicated horizontally from the vertical axis, showing potential market equilibrium points. Vertical lines at quantities 10, 12, and 15 bushels show production levels at different price levels.

### Question

"Refer to Figure 9.2. If demand for wheat is \( D_3 \), then in the long run"

- \( \text{a. None of these is correct.} \)
- \( \text{b. the firm will exit the industry.} \)
- \( \text{c. new firms will enter the industry.} \)
- \( \text{d. the firm will shut down.} \)

This question assesses the implications of demand changes on industry dynamics and firm behavior, invoking concepts like market entry and exit based on profitability.
