**Problem Statement:**

6. What price should firm Y charge if firm X charges $2? Why? What price should firm X charge if firm Y charges $4? Why?

**Payoff Matrix Explanation:**

The diagram above is a payoff matrix representing the pricing strategies of two competing firms, X and Y. Each firm can choose to charge either $2 or $4. The profits for each combination of prices are displayed in the cells where Firm X's profits are denoted by \(\pi_X\) and Firm Y's profits by \(\pi_Y\).

- **Firm X pricing options:** $2 and $4
- **Firm Y pricing options:** $3 and $4

**Matrix Details:**

- If Firm X charges $4 and Firm Y charges $4:
  - \(\pi_X = 250\)
  - \(\pi_Y = 350\)

- If Firm X charges $3 and Firm Y charges $4:
  - \(\pi_X = 300\)
  - \(\pi_Y = 150\)

- If Firm X charges $4 and Firm Y charges $3:
  - \(\pi_X = 150\)
  - \(\pi_Y = 300\)

- If Firm X charges $3 and Firm Y charges $3:
  - \(\pi_X = 200\)
  - \(\pi_Y = 200\)

**Analysis:**

1. **If Firm X charges $2:**
   - To determine Firm Y's best response, we compare Firm Y's profits between charging $3 (\(\pi_Y = 300\)) and $4 (\(\pi_Y = 350\)).
   - Firm Y should charge $4 because it maximizes its profit (\(\pi_Y = 350\) vs. \(\pi_Y = 300\)).

2. **If Firm Y charges $4:**
   - We compare Firm X's profits between charging $2 (\(\pi_X = 250\)) and $3 (\(\pi_X = 300\)).
   - Firm X should charge $3 as it yields a higher profit (\(\pi_X = 300\) vs. \(\pi_X = 250\)).
