Consider a model of an upstream manufacturer producing a good that it sells to a downstream retailer for resale. Both the upstream manufacturer and the downstream retailer are monopolists. Inverse market demand for the final good is given by P = 100 - Q. The marginal cost for the upstream firm is 40 per unit of good produced. The retailer faces no costs other than the cost of purchasing the good from the manufacturer.
b) Now, suppose that the upstream and downstream firms merge. Derive the profit maximizing price and quantity, and the corresponding profits. Are consumers better off or worse off as a result of the merger? Provide a careful economic explanation for your answer.
b) Merger:
TR = PQ = (100 - Q)Q
TR = 100Q - Q2
MR = 100 - 2Q
MC = 40
Equilibrium condition; MR = MC
100 - 2Q = 40
2Q = 60
Q = 30 units
P = 100 - Q = 100 - 30
P = $ 70
Profit = TR - TC = PQ - 40Q = Q(P - 40)
Profit = 30(70 - 40) = 30 x 30
Profit = $ 900

Q1 Consider an industry with one manufacturer M and two retail firms R1 and R2. The manufacturer produces a homogenous good at a marginal cost of 20. The retailer buys the product from the manufacturer and sells to the final consumers. Downstream demand in the industry is given by D(p) = 260 − p where p is the final retail price p. (a) As a benchmark, suppose M and R1 are vertically integrated and stop supplying R2. Which price does...
EC202-5-FY 10 9Answer both parts of this question. (a) Firm A and Firm B produce a homogenous good and are Cournot duopolists. The firms face an inverse market demand curve given by P 10-Q. where P is the market price and Q is the market quantity demanded. The marginal and average cost of each firm is 4 i. 10 marks] Show that if the firms compete as Cournot duopolists that the total in- dustry output is 4 and that if...
1. The numbers listed under each item below are the costs for producing Product A, Product B, and Products A and B together. Which set of costs exhibits economies of scope? a. 100, 150, 250 b. 100, 150, 260 c. None of these cost listings exhibit economies of scope d. 100, 150, 240 2. When MC rises above AC, then we know that a. AC declines b. AC remains the same c. AC is negative d. AC increases 3. The...

C) always increases the amount of output produced D) increases efficiency. 2) Which of the following statements is NOT true? A) AFC = AC - AVC C) AVC = wage/MPL B) AC = AFC + AVC D) C=F-VC 3) The more elastic the demand curve, a monopoly A) will have a larger Lemer Index. will face a lower...
Case: Enron: Questionable Accounting Leads to CollapseIntroductionOnce upon a time, there was a gleaming office tower in Houston, Texas. In front of that gleaming tower was a giant “E,” slowly revolving, flashing in the hot Texas sun. But in 2001, the Enron Corporation, which once ranked among the top Fortune 500 companies, would collapse under a mountain of debt that had been concealed through a complex scheme of off-balance-sheet partnerships. Forced to declare bankruptcy, the energy firm laid off 4,000...

Please read the article and answer about questions. You and the Law Business and law are inseparable. For B-Money, the two predictably merged when he was negotiat- ing a deal for his tracks. At other times, the merger is unpredictable, like when your business faces an unexpected auto accident, product recall, or government regulation change. In either type of situation, when business owners know the law, they can better protect themselves and sometimes even avoid the problems completely. This chapter...
