Question 5 In a given market the inverse demand function is P = 170-Q per year. The interest rate is r = 0.05 and the cost structure of a firm is given by C(q) = 80 q. Now assume that originally there was a Cournot duopoly in the market (with equal costs) and that it would be too costly for the research institute to enter the market. Answer the following: If the research institute sells an exclusive license at a fixed annual fee L to firm 1 (with the threat of going to the other firm if firm 1 rejects the offer), then The optimal annual fee is 1,600 and profits for firm 1 and 2 are 900 and 400 respectively. The optimal annual fee is 1,600 and profits for firm 1 and 2 are 900 and 900 respectively. The optimal annual fee is 2,100 and profits for firm 1 and 2 are 400 and 900 respectively. The optimal annual fee is 2,100 and profits for firm 1 and 2 are 400 and 400 respectively.

AP CollegeBoard Test Booklet Unit 4 Problem Set Include correctly labeled diagrams, if useful or required, in explaining your answers. A correctly labeled diagram must have all axes and curves clearly labeled and must show directional changes. If the question prompts you to “Calculate," you must show how you arrived at your final answer. Use the graph provided below to answer parts (a)-(e). Marginal Cost Average Total Cost Average Variable Cost 108 100 55 Demand 0 10 21 31 44 57 77 Quantity Marginal Revenue BigMed, a profit-maximizing firm, has a patent on a medical device, making it the only producer of that device. The graph above shows BigMed's demand, marginal revenue, average total cost, average variable cost, and marginal cost curves. (a) Calculate BigMed's total revenue if the firm produces the allocatively efficient quantity. Show your work. (b) Starting at a price of $100, if BigMed were to increase the price by 2%, will the quantity demanded decrease by more than 2%, by less…
