DEPARTMENT OF ECONOMICS Economics 340H – FA 07 OSH Assignment #3 Instructor: Christopher Michael Due Date: Dec 6, 2007 Question 1 – Perfect Competition and Monopolistic Competition Superior Metals Company has seen its sales volume DECLINE over the last few years as the result of rising foreign imports. In order to INCREASE sales (and hopefully, profits), the firm is considering a price reduction on luranium, a metal that it produces and sells. The firm currently sells 60,000 kilos of luranium a year at an average price of $10 per kilo. Fixed costs of producing luranium are $250,000. Current variable costs per kilo are $5. The firm has determined that the variable cost per kilo could be reduced by $0.50 if production …show more content…

As a niche manufacturer, Embraer makes aircraft that offer excellent reliability and cost effectiveness. To illustrate the price leadership concept, assume that total and marginal cost functions for Airbus (A) and Embraer (E) aircraft are as follows: TCA = $10,000,000 + $35,000,000QA + $250,000QA2 MCA = $35,000,000 + $500,000QA TCE = $200,000,000 + $20,000,000QE + $500,000QE2 MCE = $20,000,000 + $1,000,000QE Boeing’s total and marginal cost relations are as follows: TCB = $4,000,000,000 + $5,000,000QB + $62,500Q2B MCB = ΔTCB/ΔQB = $5,000,000 + $125,000QB The industry demand curve for this type of jet aircraft is: Q=910 - 0.000017P Assume throughout this problem that the Airbus and Embraer aircraft are perfect substitutes for Boeing’s Model 737-600, and that each total cost function includes a risk-adjusted normal rate of return on investment. A. Determine the supply curves for Airbus and Embraer aircraft, assuming that the firms operate as price takers. B. What is the demand curve faced by Boeing? C. Calculate Boeing’s profit-maximizing price and output levels. (Hint: Boeing’s total and marginal revenue relations are TRB = $50,000,000QB - $50,000Q2B, and MRB =ΔTRB/ΔQB = $50,000,000 - $100,000QB.) D. Calculate profit-maximizing output levels for the Airbus and Embraer aircraft. E. Is the market for aircraft from these three firms in short-run or long-run
