Suppose there are two firms in an industry, X and Y. Demand for each firm’s product is,
Suppose there are two firms in an industry, X and Y. Demand for each firm’s product is,
respectively:
QDX = 90 – 3PX + 2PY
QDY = 90 – 3PY + 2PX
Both firms also face a constant marginal cost of 10 per unit: MCX = MCY = 10, and there are no fixed costs for either firm.
Using the example above as a guide, find the equations that characterize the “best responses” for each firm, expressing each firm’s optimal price in terms of the rival’s price:
Firm X’s best response:
Firm Y’s best response:
Firm X’s equilibrium price:
Firm Y’s equilibrium price:
