Additional Problem 3: Assume two companies (C and D) are Cournot duopolists that produce identical products. Demand for the products is given by the following linear demand function: ? = 600 − ?C − ?D where ?C and ?D are the quantities sold by the respective firms and P is the price. Total cost functions for the two companies are ??C= 25,000 +100?C 2 ??D = 20,000 + 125?D c. Determine the equilibrium price and quantities sold by each firm. d.Determine the profits for the market as well as eachfirm.
Suppose that the market demand curve for your product is given by: Q=$25-0.5P. Assume that the marginal cost and average total cost equal $34 for all levels of production. The marginal revenue curve would be given by the equation: MR= (Carefully enter your response as an algebraic expression, using the proper notation in the proper format.) The adjacent figure shows the demand curve (D) and the marginal revenue curve (MR) for your product. Using the line drawing tool, plot the marginal cost (MC) and the average total cost (ATC) curves. Using the point drawing tool, show the profit-maximizing price and quantity for your firm. Carefully follow the instructions above and only draw the required objects. Economic profit earned by your firm will be equal to $. Price (dollars/unit) $60 $50- $40- $30- $20- $10- $0- 0 MR 12 Quantity (units) 16 D 20
Be sure to explain your answers. 2. Consider a market for a homogenous good with the following inverse demand function: P = 52 – 20 where Qis total sold quantity on the market. + (a) If there is only one firm serving the market and the firm's cost function is C(O) = 4Q, what quantity will be sold on the market? What will be the market price? What is the firm's profits? Is the market outcome efficient? (b) Suddenly, there is a potential rival firm considering entering the market. It would produce the same good as the incumbent firm and would have an identical variable cost but has a fixed cost of entry, F = 100. The two firms would be faced with a problem of simultaneously deciding on how of the good to sell on the market (the inverse demand function is still the same). Derive both firms' best response functions and draw these in a diagram. Explain the Nash equilibrium in the diagram. (c) Following from (b), what would be the new equilibrium quantity sold in the market and what is the…

The demand curve for each firm is given by 91 = 1000-2P₁ + P₂ 92 = 1000-2P₂ + P₁ Their total cost functions are given as: TC₁ = 100q₁ TC₂ = 10092 i) ii) iii) iv) Determine the equilibrium price, output and profit for each firm assuming that they move simultaneously Determine the equilibrium price, output and profit for each firm assuming that firm 1 moves first and firm 2 afterwards Suppose the two firms collude, determine the equilibrium price, output and profit for each firm Construct a prisoner's dilemma scenario and determine the Nash equilibrium
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.
The Lead Zeppelin Company produces powered and steerable lighter-than-air craft. The company’s airships are specially lined and are therefore safer than normal dirigibles. The table below shows the weekly production of dirigibles, along with the associated Average Cost and Total Revenue figures (the Average Cost and Total Revenue figures are actually in thousands of dollars, so the $15 represents $15,000, but we have left off the zeros to save space). Quantity Average Cost Total Cost Total Revenue 0 -- 0 $0 1 $15 15 $10 2 $9 18 $20 3 $8 24 $30 4 $8.50 34 $40 5 $9 45 $50 6 $10 60 $60 7 $12 84 $70 The Lead Zeppelin Company has decided that it will produce at least 1 dirigible. Now the question becomes, how many more dirigibles should it produce to make as much profit as possible? Use the profit-maximizing rule to explain how many dirigibles the Lead Zeppelin Company should produce to…
Eric owns a plot of land in the desert that isn't worth much. One day, a giant meteorite falls on his property, making a large crater. The event attracts scientists and tourists, and Eric decides to sell nontransferable admission tickets to the meteor crater to both types of visitors: scientists (Market A) and tourists (Market B). The following graphs show daily demand (DD) curves and marginal revenue (MRMR) curves for the two markets. Eric's marginal cost of providing admission tickets is zero.

Problem 2: Presently, APlus Transport and Big Movers are the only suppliers of services that haul heavy construction equipment between jobs within the Midwest. No other suppliers have the equipment necessary to perform the service. The market inverse demand for these hauling services is given below. P = 4,030-4Q where P is price per trip and Q is total number of trips per year. For simplicity, also assume that neither firm has fixed costs. From company records, you are given the following variable cost function for each firm: a. C. TVC = 300 TVCB = 80QB b. Calculate the Cournot market equilibrium price-output solutions for each firm including their respective profits. d. Assume these two competitors operate as a two-firm Cournot duopoly. Find the reaction functions for each firm. Suppose Big Movers shuts down operations so that APlus now has a monopoly in this market. What is the price, quantity, and profits for APlus after this change? Summarize the results of your findings over the…
Suppose that there are two types of firms in a perfectly competitive market. Firms of type A have costs given by CA(q) = 30q2 + 10q. Firms of type B have costs given by CB(q) = 50q2 + 10. ( dCA dq = 60q + 10 and dCB dq = 100q). There are 60 firms of type A and 100 firms of type B. Derive the individual firm supply functions for each type of firm and What is the range of prices in which some firms produce but others do not? Are there prices at which no firms produce Why?
