Assignment Questions

Two firms, Alpha Vineyard and Beta Winery, produce and sell wine. The demand for

Alpha’s wine is given by the equation,

Q A = 200 − P A + P B .

In this equation, the price of Alpha’s wine is P A per bottle, and the price of Beta’s wine is

P B per bottle. Alpha Vineyard has a marginal cost of MC A = $20 per bottle, and a fixed

cost of FC A = $6000. The demand for Beta’s wine is given by the equation,

Q B = 9000 − 100P B + 40P A .

Beta Winery has a marginal cost of MC B = $10 per bottle, and a fixed cost of FC B =

$10,000. The two firms compete by simultaneously selecting prices.

Question 1: Are the bottles of wine produced by Alpha Vineyard and Beta Winery, homo-

geneous products or heterogeneous products? Your answer must reference the two firms’

demand functions. (3 Marks)

Question 2: Find Alpha Vineyard’s best-response function. (4 Marks)

Question 3: Find Beta Winery’s best-response function. (4 Marks)

Question 4: In equilibrium, what price does each firm charge for a bottle of wine? How

many bottles of wine does each firm sell? What is each firm’s profit? (4 Marks)

Question 5: Which firm has the greater market power? Explain. (3 Marks)

Question 6: How would the equilibrium that you found in question 4 change if Beta Win-

ery’s fixed cost increased to FC B = $100,000? (2 Marks)
