Suppose duopolists face the demand curve P (q) = 4-q firm one has costs c(q1)=2q1 and firm two has costs c(q2)=2q2 What is the optimal quantity if firm one moves first in a Stackelberg competition?

Tom is a monopolist input supplier to Dic and Harry. Tom's marginal cost is 1. Dic and Harry are duopolists with production function q = x1/2. No firm has fixed costs. The demand for the final product is given by Q = 100 – p. a) Assume Dic and Harry buy the input from Tom at price k. What are their cost functions? b) Find the Cournot equilibrium quantities. c) What price, k, should Tom set? -

A monopolist can produce at a constant average and marginal cost of ATC = MC = $5. It faces a market demand curve given by Q = 53 - P.    Suppose there are N firms in the industry, all with the same constant MC = $5. Find the Cournot equilibrium. How much will each firm produce, what will be the market price, and how much profit will each firm earn? Also show that as N becomes large, the market price approaches the price that would prevail under perfect competition. (Hint: your answers will be functions of N)(BONUS)

Imagine any market divided by 2 Cournot oligopolists who have identical costs Marginal cost = Average cost = 200. About this market, ask yourself: a) If the demand curve for this market is given by Q = 1250 - 2.5P, where Q is the total quantity demanded in the market and P is the selling price, both given in units, what is the reaction curve of the oligopolists? b) What will be the quantity produced and the selling price of the oligopolists? c) A strategist considers that a good marketing campaign would be able to expand the Demand of this market to Q = 1,500 - 2.5P and that in this way, oligopolists could produce the same amount and make significantly greater profits. Such a campaign would generate a reduction in profits in the order of 70,000. Is it worth making this investment in marketing?

There are two firms selling differentiated products.  Firm A faces the following demand for his product:  QA=20-1/2PA+1/4PB Firm B faces the following demand: QB=220-1/2PB+1/4PA PA represents the price set by firm A. PB represents the price set by firm B.Assume that the marginal cost is zero both for firm A and firm B.What are the equilibrium prices of a simultaneous price competition?What would the equilibrium prices be if A is the leader and B is the follower?

Suppose two firms compete as Bertrand duopolists for an identical product, where demand is given by Q = 5000 – 50P and both firms have marginal cost of 10 per unit of output. If firm 1 has capacity of 1500 and firm 2 has capacity of 2000, what will the equilibrium price be in this market?

Suppose the inverse demand function for two Cournot dupolists is given by P= 10 – (Q1+Q2) and their cost are zero.a) What is each firm marginal revenue?b) What are the reaction function for the two firmsc) What are the Cournot equilibrium outputd) What is the equilibrium price?

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)

Consider the following Stackelberg duopoly. Both firms produce a homogenous good. Firm 1 chooses how much to supply first. Firm 2 chooses how much to supply after observing the quantity supplied by firm 1. The market demand is Q= 100 – 4 P. For firm i, the total cost of production is TC(q) =5q,+2. What is the optimal quantity supplied by firm 12 10 20 30 40 QUESTION 6 Consider the following Stackelberg duopoly. Both produce a homogenous good. Firm 1 chooses how much to supply first. Firm 2 chooses how much to supply after observing the quantity supplied from firm 1. The market demand is Q= 100 - 4P. For firm i, the total cost of production is TC(q) =5q,+2. What is the market clearing price? O 10 O 15 20 O 25
