- 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 unchanged. In this case, what will firm B’s optimal output be? (Justify your answer.) What will firm A’s profit be?usiness EconomicsQ&A LibraryTwo firms A and B produce an identical product (Note: Industry Output = Q). The firms have to decide how much output qA and qB (Note: qA = Firm A Output; qB = Firm B Output) they must produce since they are the only two firms in the industry that manufacture this product. Their marginal cost (MC) is equal to their average cost (AC) and it is constant at MC = AC = X, for both firms. Market demand is given as Q = Y – 2P (where P = price and Q = quantity). Select any value for X between [21 – 69] and any value for Y between [501 – 999].

- There are only two driveway paving companies in a small town, Asphalt, Inc. and Blacktop Bros. The inverse demand curve for paving services is ?= 2040 ―20? where quantity is measured in pave jobs per month and price is measured in dollars per job. Assume Asphalt, Inc. has a marginal cost of $100 per driveway and Blacktop Bros. has a marginal cost of $150. Answer the following questions: Determine each firm’s reaction curve and graph it. How many paving jobs will each firm produce in Cournot equilibrium? What will the market price of a pave job be? How much profit does each firm earn?Question 2: A market is contested by two firms, A and B, who compete in selling a homoge- neous good. Market demand is given by Q = 240 3p, where p is the price of the good. Firm A has constant marginal costs of 20 as long as it produces 100 units or fewer. Every unit above 100 costs 75 to produce. Firm B has the cost function CB = Q3, where QB is the quantity produced by firm B. The firms sequentially choose prices. A is the market leader and chooses its price first; B chooses its price after observing A's price. If they charge the same price each sells half of the demand at that price. The firms cannot turn away customers. What is the equilibrium price in this industry?Mavi and Diesel both make basic blue jeans. The demand curves for the two firms are given by Qm=135,000−3000Pm+1200Pd Qd=154,000−4000Pd+1000Pw suppose it is a price equilibrium for Mavi to set a price of $30 per pair of jeans and Diesel to set a price of $25. What is marginal cost for Mavi What is marginal cost for Diesel
