- Consider a Cournot duopoly. The market demand function is P = 180 – 2(q₂ + q₂), where P is the market price, q₂ is the output produced by Firm 1 and q₂ is the output produced by Firm 2. The two firms have a constant marginal cost c = 30. What is the total output in this market? Round your answer to the nearest integer (e.g. 50)Suppose we have a duopoly with Firm 1 and Firm 2 and the following inverse demand function:P = 100 – 5(Q1 + Q2)Total Cost and Marginal Cost values for firms 1 and 2 are:TC1 = 20Q1TC2 = 30Q2MC1 = 20MC2 = 30Assuming a Cournot Duopoly, the following response functions are derived:Firm 1: Q1 = 8 – 0.5Q2Firm 2: Q2 = 7 – 0.5Q1Using this information, calculate the quantity produced for each firm, the price, and profits foreach firm and the market as a whole.Gamma and Zeta are the only two widget manufacturers in the world. Each firm has a cost function given by: C(q) = 10+20q + q^2, where q is number of widgets produced. The market demand for widgets is represented by the inverse demand equation: P = 200 - 2Q where Q = q1 + q2 is total output. Suppose that each firm maximizes its profits taking its rival's output as given (i.e. the firms behave as Cournot oligopolists). a) What will be the equilibrium quantity selected by each firm? What is the market price? What is the profit level for each firm? Equilibrium quantity for each firm__ price__ profit__ b) It occurs to the managers of Gamma and Zeta that they could do a lot better by colluding. If the two firms were to collude in a symmetric equilibrium, what would be the profit-maximizing choice of output for each firm? What is the industry price? What is the profit for each firm in this case? Equilibrium quantity for each firm__ price__ profit__ c) What minimum discount factor is required…

The quantity that each firm will produce in the Cournot equilibrium is A. 12 B. 6 C. 3 D. 18Consider two Cournot oligopolists, firm 1 and firm 2, in a homogenous product market. The market demand is P = 100 – 3Q and each firm has a constant marginal cost MC=10. The Cournot equilibrium quantity for each firm is: a. 7.5 b. 10 c. 5 d.15Consider a duopoly, i.e., an industry with only two firms: firm A and firm B, making the same product. The industry’s inverse demand is P(Q)=320−(1/5)Q, where P is the market price and Q is the total industry output. Each firm has a marginal cost MC of $20. There are no fixed costs and no barriers to exit the market. a) Suppose that the two firms engage in Cournot competition. Find the equilibrium price PNE in the industry, the equilibrium outputs QANE and QBNE, as well as the profits πANE and πBNE, for each firm. b) Suppose the marginal cost for firm B increases from $20 to $140, while everything else remains unchanged. Find the new equilibrium price PNE in the industry, the new equilibrium outputs QANE and QBNE, as well as the new profits πANE and πBNE for each firm. c) Suppose that, in addition to the marginal cost increase from $20 to $140 from sub question b), firm B also has a fixed cost of $2500, out of which $2100 may be recouped if it shuts down; everything else remains…
- Cournot’s Model of Duopoly) Joe and Rebecca are small-town ready-mix concrete duopolists. The market demand function is Qd=5500-25P, where P is the price of a cubic metre of concrete and Qd is the number of cubic metres demanded every year. The marginal cost is $40 per cubic metre. Competition in this market is described by the Cournot model. (a)Given Rebecca’s output is 2000, what is Joe’s residual demand function? What is Joe's output so he maximizes his profit? (b)If Rebecca’s output is qR, what is Joe’s best response function? (c)If Joe’s output is qj, what is Rebecca’s best response function? (d)Plot both Joe and Rebecca’s best response functions on one graph, where the the horizontal axis represents Rebecca’s output qR and the vertical axis represents Joe's output qR. (e)What is the meaning of the interception of the two best response functions?If the inverse demand for bean sprouts were given by P(Y) = 430 − 2Y and the total cost of producing Y units for any firm were TC(Y) = 10Y and if the industry consisted of two Cournot duopolists, then in equilibrium each firm's production would beQuestion 2Bob and Alice are duopoly competitors for ice cream in Venice Beach,CA. Market demand for ice cream is p = 1000 − 2Q and both Alice’sand Bob’s costs of production are identical and given by C(q) = 4q.Calculate market price and quantity ifa) Alice and Bob are in Cournot competition.b) Alice and Bob are in Bertrand competition.c) Alice and Bob decide to coordinate their decisions in a cartel (i.e.to build a monopoly) and to equally share profits.
- Try the analysis with an n-firm Cournot oligopoly in which one firm innovates to reduce cost from c to c/2. For this problem, assume n = 2, and use the demand and cost numbers used in the lecture. That is, let inverse market demand be given by P = 100 - Q, and let marginal cost be constant at 50 per unit before the innovation, and 25 per unit after the innovation. (a) Compute what the duopolist stands to gain from innovating. How does it compare to the perfectly competitive firm and to the monopolist? (b) What can you conclude about the relationship between concentration and innovationTwo firms engage in Cournot competition in the Everlasting Gobstopper industry. The price elasticity of demand is -2. Firm 1 has a constant marginal cost of $365.00 per unit, and firm 2 has a constant marginal cost of $602.25 per unit. If the two firms are currently in equilibrium, what is firm 2's share of the market? Enter your answer as a decimal, rounded to two places if necessary.The market for dark chocolate us characterized by Cournot duopolists - Honeydukes and Wonka industries. The market demand for dark chocolate is: P = 8 - 0.005Qd where P is the price per bar in dollars and Qd is dark chocolate's daily quantity demanded in bars (use qh to represent the quantity of dark chocolate sold by Honeydukes and qw to represent the quantity of dark chocolate sold by Wonka Industries). Honeydukes has a constant marginal cost of $2.50 per bar, while Wonka Industries has a constant marginal cost of $3.00 per bar. The firms move simultaneously in choosing their profit-maximizing quantity of output. a. Given the firms move simultaneously, what is the equation for Honeydukes' reaction function with qh expressed as a function of qw? b. Given the firms move simultaneously, what is the equation for Wonka's reaction function with qw expressed as a function of qh? c.
