P = 100 – (Q1 + Q2) C1(Q1) = 2Q1 C2(Q2) = 2Q2
a. Cournot: Assume two Cournot duopolists.
i. What is firm 1’s Quantity and Profit?
R1 = (100-Q1-Q2) * Q1
R1 = 100Q1 - Q12 - Q2Q1
MR1 = 100 - 2Q1 - Q2
C1(Q1) = 2Q1
MC1 = 2
MR1 = MC1
ii. What is firm 2’s Quantity and Profit?
R2 = (100-Q1-Q2) * Q2
R2 = 100Q2 - Q1Q2 -Q22
MR2 = 100 - Q1 - 2Q2
iii. What is the market Price?
b. Stackelberg: Assume two firms in a homogeneous-product Stackelberg oligopoly, where firm 1 is the leader and firm 2 is the follower.
i. What is firm 1’s Quantity and Profit?
ii. What is firm 2’s Quantity and Profit?

c. Which (of the four) firms makes the highest profit? The lowest profit?
d. Which market has the lowest market price (Cournot or Stackelberg)?

Two firms are participating in a Stackelberg duopoly. The demand function in the market is given by Q = 2000 − 2P. Firm 1’s total cost is given by C1(q1) = (q1) 2 and Firm 2’s total cost is given by C2(q2) = 100q2. Firm 1 is the leader and Firm 2 is the follower. (1) Write down the inverse demand function and the maximization problem for Firm 1 given that Firm 2 is expected to produce R2(q1). (2) Compute...
Questions 10-12 rely on the following prompt: Firm 1 and Firm 2 compete as Cournot duopolists, producing q1 and q2 units of output respectively, such that market output Q=q1+q2. They face market inverse demand of P = 400 − 2Q. Firm 1’s Total cost is given by TC1=2q1^2. Firm 2’s by TC2=2q2^2. 10. What is Firm 1’s equilibrium profit maximizing output level, q1*? 11. What is market output in the Cournot equilibrium for this market (so, what is the value...
Consider two symmetric Cournot duopolists who face inverse market demand of p = 140−Q. Suppose that they each have long-run cost functions Ci(qi) = 20qi for i = 1, 2. (a) Draw a graph containing the demand and marginal cost curves. (b) What are the efficient quantity and price, QC and pC? How much total surplus is generated at this quantity and price? (c) What are the monopoly quantity and price, QM and pM ? How much profit would a...
4. Consider 2 firms selling fertilizer competing as Cournot duopolists. The inverse demand function facing the fertilizer market is P = 1 - where Q = 94 +98. For simplicity, assume that the long-run marginal cost for each firm is equal to X, i.e. C(q)=Xq for each firm. a) Find the Cournot Nash equilibrium where the firms choose output simultaneously b) Find the Stackelberg Nash Equilibrium where firm A as the Stackelberg leader. How much does the leader gain by...
Reference the following information about the market demand function for questions 1 to 15. These questions are on different types of market structures – monopoly, perfect competition, Cournot oligopoly market, and the Stackelberg oligopoly market. The market demand function is given the following equation: P = 1600 – Q where Q is the industry’s output level. Suppose initially this market is served by a single firm. Let the total cost function of this firm be given the function C(Q) =...
1. Consider two Cournot duopolists. Each firm sells a homogenous product and has a MC = c per unit, and no fixed costs. Market demand is P = a−bQ, where market quantity sold Q = q1 +q2, where q1 is firm 1’s output and q2 is firm 2’s output. Each firm simultaneously chooses its quantity to sell, then lets price clear the market. a. What is firm 1’s best response function (or reaction function)? b. Solve for the profit maximising...
The inverse market demand is P=160 – 4Q. The firms have cost functions TC1 = 8+12q1+2q1² TC2 = 8+12q2+2q2² a. Determine monopoly profit-maximizing output for each firm. Determine the industry profit-maximizing output under collusion. Calculate the equilibrium price under collusion. Determine if the firms should collude. Assume your initial game is Cournot. Joint profits Profits Collusion = $1079.2 Profits Cournot = 1010.75 Profits Stackelberg = 971.17 Profit monopoly 1 = 904.67 Profits monopoly 2 = 904.67 Collude since...
3. Two firms in the market, 1 and 2, face an inverse demand function given by P(Q1 +Q2) = 400 – 2Q1 – 202 where Q1 is the level of production of firm 1 and Q2 is the level of production of firm 2. The cost function of firm 1 is C1 (Q1) = (Q1) and the cost function of firm 2 is C2 (Q2) = (Q1). The two firms compete in quantities (i.e., Cournot competition). (a) Set up the...
Two identical firms compete as a Cournot duopoly. The inverse market demand they face is P = 120-2Q. The total cost function for each firm is TC1(Q) = 4Q1. The total cost function for firm 2 is TC2(Q) = 2Q2. What is the output of each firm? Find: Q1 = ? Q2 = ?
Two firms compete in a market to sell a homogeneous product with inverse demand function. P = 500 – 2Q. Each firm produces at a constant marginal cost of $100 and has no fixed costs.
