- Market demand is given by P = 28 - 1⁄2 Q. There is a single incumbent firm with constant MC = AC = 5, facing one possible entrant. That entrant must enter with an output no less than 4 units, after which its MC = 6. If the incumbent wants to deter entry, what output should it choose and maintain?2. Suppose market demand is p = 20 - Q. Firms cost functions are identical: C=5+2q. If firm A is the incumbent, can it deter the entry of its rival, firm B?Suppose Firm X is a dominant firm in a market where the market demand is Q = 1200 -2p. Once Firm X sets its price, those small competitors set their prices a little lower so that they can always sell up to their capacity. Assume the small firms’ combined capacity is 100 units. Further assume Firm X’s marginal cost is 50. Answer the following questions. Let Q^D be the quantity produced by the dominant firm. Write down the residual demand function faced by Firm X. (Hint: Think about how Q and Q^D are related.) Find Firm X’s profit-maximizing price.
- Question Consider a market with an inverse demand Function p = 60 -4*Q. There are two firms, an incumbent and an entrant. There is a constant variable cost of 6 and a unit capacity cost of 6. In the first stage, the incumbent chooses capacity. In the second stage, the entrant decides whether or not to enter and all active firms choose quantities (where the entrant also has to simultaneously choose its capacity in the second stage, if it enters). a. For a capacity of 5 units, what is the best response function of the incumbent in the second period? b. What is the Cournot-Nash equilibrium of the second stage if the incumbent chose a capacity of 5 units in the first stage conditional on the entrant entering? c. For a capacity of an arbitrary k units, what is the best response function of the incumbent? d. What is the Cournot-Nash equilibrium of the second stage if the incumbent chose a capacity of k units in the first stage conditional on the entrant entering? e. Solve for the subgame…Glyde Air Fresheners is the dominant firm in the solid room aromatizer industry, which has a total market demand given by Q = 80 - 2P. Glyde has competition from a fringe of four small firms that produce where their individual marginal cost equals the market price. The fringe firms each have a total cost given by: TCi = 10Qi + 2Qi2. If Glyde’s total costs are given by TCG = 100 + 6QG a) what price should Glyde establish for air fresheners? b) what is Glyde’s maximum profit?AVAC is the only pharmaceutical firm producing a Vaccine. The Demand Curve for its product is Qd = 250 – 50 P where P is Price and Q are packs of vaccines in ‘000 Total Cost Function estimated by the firm is TC = 15 + 0.5Q where Q is monthly output. What is the market structure of AVAC? State its characteristics. To maximize profit, What will be the optimum price and how many packs of Vaccine should the firm produce and sell per month?

- AOF is the only firm selling beer around Isla Vitas, which has a beer fountain in the backyard so the marginal cost of producing beer is 0. There are two groups of consumers: students and non students. The students' beer inverse demand function is p=50-5q, and the non-students' beer inverse demand function is p=10-2q. AOF sells beer in two sizes: 10 ounces bottle and 5 ounces can. Due to a local act, the consumers can only buy either 1 bottle or 1 can of beer. AOF can charge different prices on each bottle and each can of beer, while it cannot tell whether a customer is a student or not. In order to maximize the profits, how much should AOF charge its 10 ounces bottle? Answer: 87.5AOF is the only firm selling beer around Isla Vitas, which has a beer fountain in the backyard so the marginal cost of producing beer is 0.

- Consider a market with only one firm and total barriers to entry in which the demand curve is given by P = 80 – 2Q and MR = 80 – 4Q. Suppose that total costs is equal to 0 (hence, marginal cost is equal to 0). What would be the prevailing price in this market? P = 20 P = 50 P = 30 P = 40Glyde Air Fresheners is the dominant firm in the solid room aromatizer industry, which has a total market demand given by Q = 80 - 2P. Glyde has competition from a fringe of four small firms that produce where their individual marginal costs equal the market price. The fringe firms each have total costs given by TC; = 10Q; + 2Q²;. If Glyde's total costs are given by TCG = 100 + 6QG, what are the total profits of the fringe firms?Suppose 4Sisters is a patented vaccine. Her producer is facing a linear demand function for 4Sisters. She manufactures at a constant marginal cost of $20. Reports indicate that she produces 12,000 units of vaccine. She charges a unit price of $400. She is making a positive economic profit of $1,500,000. Draw a well-labelled diagram to indicate the output decision, pricing decision, economic profit, and the resultant deadweight loss in the market for 4Sisters. Indicate key figures with reference to the above given information.
