Consider two firms, Firm A and Firm B, who compete as duopolists. Each firm produces an identical product. The total inverse demand curve for the industry is ? = 250 − (?? + ?? ). Firm A has a total cost curve ?? (?? ) = 100 + ?? 2 . Firm B has a total cost curve ?? (?? ) = 100 + 2??.

a. Suppose for now, only Firm A exists (?? = 0). What is the Monopoly equilibrium quantity and price? What is Firm A’s profit?

b. Find the Nash Cournot equilibrium price and output level. What are the firms’ profits?

c. Find the equilibrium price and output level in the market if firm A acts as a Stackelberg leader. What are the firms’ profits?

d. Suppose that the two firms are able to form a cartel. Derive the output each firm will produce, the market price, and the total profit under the cartel solution.

e. Compare the Cournot, Stackelberg, and Cartel outcomes to the monopoly outcome you calculated in part a.

Suppose duopolists face the market inverse demand curve P = 100 - Q, Q = q1 + q2, and both firms have a constant marginal cost of 10 and no fixed costs. If firm 1 is a Stackelberg leader and firm 2's best response function is q2 = (100 - q1)/2, at the Nash-Stackelberg equilibrium firm 1's profit is $Answer

The market demand function is Q=10,000-1,000p. Each firm has a marginal cost of m=$0.16. Firm 1, the leader, acts before Firm 2, the follower. Solve for the Stackelberg-Nash equilibrium quantities, prices, and profits. Compare your solution to the Cournot-Nash equilibrium. The Stackelberg-Nash equilibrium quantities are: q1=___________ units and q2=____________units The Stackelberg-Nash equilibrium price is: p=$_____________ Profits for the firms are profit1=$_______________ and profit2=$_______________ The Cournot-Nash equilibrium quantities are: q1=______________units and q2=______________units The Cournot-Nash equilibrium price is: p=$______________ Profits for the...

Consider two firms with the cost function TC(q) = 5q (constant average and marginal cost,of 5), facing the market demand curve Q = 53 – p (where Q is the total of the firms’ quantities, and p is market price). a. What will be each firm’s output and profit if they make their quantity choices simultaneously (as Cournot duopolists)? b. Now suppose Firm 1 is the Stackelberg leader (its decision is observed by Firm 2 prior to that firm’s decision)....

Suppose there are 2 firms in a market. They face an aggregate demand curve, P=400-.75Q. Each firm has a Cost Function, TC=750+4q (MC=4). a. If the 2 firms could effectively collude, how much would each firm produce? What is aggregate output? What is price? What are the profits for each firm? Provide a graph illustrating your answer. b. Suppose instead that the firms compete in Quantity (Cournot Competition). Calculate each firm's best-response function using the formulae provided in the book....

Consider the following market: Two firms compete in quantities, i.e., they are Cournot competitors. The firms produce at constant marginal costs equal to 20. The inverse demand curve in the market is given by P(q) = 260 − q. a. Find the equilibrium quantities under Cournot competition as well as the quantity that a monopolist would produce. Calculate the equilibrium profits in Cournot duopoly and the monopoly profits. Suppose that the firms compete in this market for an infinite number...

Suppose there are two firms in the market. Let Q1 be the output of the first firm and Q2 be the output of the second. Both firms have the same marginal costs: MC1 = MC2 = $5 and zero fixed costs. The market demand curve is P = 53 − Q. (a) (6 points) Suppose (as in the Cournot model) that each firm chooses its profit-maximizing level of output assuming that its competitor’s output is fixed. Find each firm’s reaction...
