In a duopoly, each firm has marginal cost MC = 100, and market demand is Q = 500 - 0.5p.

Assuming average cost is the same as marginal cost.

In which oligopoly, Cournot or Stackelberg, do firms have more market power?

a. Cournot since the Lerner Index in the Cournot model is twice as much as that in the Stackelberg model.

b. Stackelberg since the Lerner Index in the Cournot model is twice as much as that in the Stackelberg model.

c. Cournot since the Lerner Index in the Cournot model is about 1.08 times as much as that in the Stackelberg model.

d. Stackelberg since the Lerner Index in the Cournot model is about 1.08 times as much as that in the Stackelberg model.

The market demand function is Q = 7000 - 1000p Each firm has a marginal cost of m = $0.16 Firm 1, the leader, acts before Firm 2, the follower. Solve for the Stackelberg-Nash equilibrium quantities, prices, and profits. Compare your solution to the Cournot-Nash equilibrium. The Stackelberg-Nash equilibrium quantities are: q1 = _______ units and q2 = ________ units. The Stackelberg-Nash equilibrium price is: Profits for firm 1 is: Profits for firm 2 is: The Cournot-Nash equilibrium price is:...

A monopolist has a marginal cost curve MC=Q and a home market demand P=30-Q. The monopolist can also sell in a foreign market at a price pf Pf=12. Find and graph the quantity produced, quantity sold at home, and quantity sold in the foreign market, as well as the price charged at-home market. Explain why the monopolist's profits would fall if it were to produce the same quantity but sell more in the home market.
