- Consider an industry with N firms that compete by setting the quantities of an identical product simultaneously. The resulting market price is given by: p = 1000 − 4Q. The total cost function of each firm is C(qi) = 50 + 20qi . (a) Derive the output reaction of firm i to the belief that its rivals are jointly producing a total output of Q-i . Assuming that every firm produces the same quantity in equilibrium, use your answer to compute that quantity. (b) Suppose firms would enter (exit) this industry if the existing firms were making a profit (loss). Write down a mathematical equation, the solution to which would give you the equilibrium number of firms in this industry. You don’t have to solve this equation.An upstream firm (U) sells an input to a downstream firm (D) which resells it to consumers. The marginal cost of U is 4. Each unit is sold by U to D at a transfer price r. Requirement final is p = 12 - y. a) Suppose U and D are separate firms. Find r, y and p. b) Suppose U and D are one integrated firm. Find p and y. c) Suppose the firms are not integrated, but firm U uses a two-part tariff: it requires payment of r for each unit sold to D; in addition, it requires payment lump sum of T.

- 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?Exercise 6.8. Two companies with cost functions C1 (q1 )=5q1 and C2 (q2)= 0.5 q2 ² supply the to the same market. If the inverse market demand function is given by P = 100 - 0,5Q , where Q = q₁ + q₂ , find a) The production level of each firm, the price and the profits if the companies compete according to the Cournot model. (b) The level of production of each undertaking, the price and the profits if the undertakings agree to jointly maximise their profits. Show the results with the help of graphs.Suppose the Boston to Philadelphia airline route is serviced by three airlines – US Airways (Firm A) and JetBlue (Firm B) and Continental (Firm C). The demand for airline travel between these two cities is Q = 150 – p. The cost function is C(Q) = 30Q. The cost function is the same for all three airlines. Assume that the three airlines are making investments in airline capacity. In other words, they are simultaneously choosing quantity. (Cournot Competition) Derive US Airways’ residual demand function given JetBlue’s output, qB, and Continental’s output, qC. What is the Marginal Revenue for US Airways? Derive US Airways reaction function Derive the market equilibrium quantity, Q*, price, p*, and Profit.
- Question 3 Suppose a market demand function is given by QD(P) = 1,000 - 10P. The product can be produced with a cost function C(Q) = 10,000 + 20Q. (a) Determine Q and P and the firm's profit if there is a single firm. (b) Determine total output Q, the equilibrium price, and the profit of each firm if there are two firms (i.e., a Cournot oligopoly). (c) Determine Q. the equilibrium price, and the profit of each firm if there are 10 firms.consider a market with inverse demand P(Q) = 10 − Q and two firms with cost curves C1(q1) = 2q1 and C2(q2) = 2q2 (that is, they have the same marginal costs and no fixed costs). They compete by choosing quantities. Suppose that Firm 1 chooses quantity first and is able to credibly commit to this choice. Then firm 2 choose its quantity after observing firm 1’s quantity. In the SPNE of this game, what is the price faced by consumers?- p = 3- p = 4- p = 5- p = 6- p = 7Firm 1 is the leader and Firm 2 the follower in the model of price leadership. Thus, Firms 1 and 2 are the only two producers of a certain good; Firm 1 chooses the price p it will commit to maintain in the market; after having observed Firm 1's decision p, Firm 2 chooses the quantity yz it will produce. Here, the firms cost functions are as follows: c(y;)=3y, +y,?/2 and c2(Y2)= y2?/4. The inverse demand curve is p(Y)=70-Y. What is true about the quantity Firm 2 will produce at the equilibrium of this model? O a. It is between 40 and 42. O b. None of the other answers. It is between 44 and 45. O d. It is between 38 and 39. Oe. It is between 43 and 43.5.
- 4. A vertically integrated automobile company has an upstream engine division and a downstream assembly division. The demand for the company's cars is given by Q = 20-P. Each car requires one engine. The downstream division's total cost of assembling cars is TCD(Q) = 4Q. The upstream division's total cost of producing engines is TCv (Q) = Q². (a) Suppose that there is no outside market for engines. What is the price and quantity of cars produced by the company? (b) Suppose that there is no outside market for engines. What should be the transfer price for engines? [Hint: the transfer price of an engine should equal the marginal cost of engine production at the optimal quantity.] (c) Suppose that there is a competitive outside market in which the price of an engine is 12. What is the price and quantity of cars produced by the company? (d) Suppose that there is a competitive outside market in which the price of an engine is 12. What is the quantity of engines that the company buys or…This question deals with cost curves and isoprofit curves. Keep in mind that the formula for a firm's cost function is: TC = FC+ C(O) TC → Total Costs: FC → Fixed Costs: C(Q) → Cost of production*Quantity produced → also known as Variable Costs Q2: Firms A and B are two firms supplying products in two separate differentiated goods markets. Equations (1) and (2) give the total cost functions of the two firms: - Firm A: TC = 2Q --- Equation (1) - Firm B: TC = 10 + 2Q --- Equation (2) Each firm has the ability to produce a maximum quantity of 80,000 units in ten batches of 8,000. The cost of production per unit for each firm is $2. Firm B has a fixed cost of $10. (a) Plot isoprofit curves valuing $34,000 and $60,000 for each of the two firms. Provide an explanation for any differences that may exist (b) Use the information given about firms A and B and appropriate diagrams/figures to explain how the equilibrium for both firms will change if a rival company increases its prices.Economics Consider a three-firm homogeneous product industry.
