- Suppose that the inverse demand for a downstream firm is P = 150 - Q. Its upstream division produces a critical input with costs of CU(Qd) = 5(Qd)2. The downstream firm's cost is Cd(Q) = 10Q. When there is no external market for the downstream firm's critical input, the downstream firm should produce:The price-demand equation for the production of bluetooth speakers is: p = 250 - 1/20x, for 0 is less than or equal to x and x is less than or equal to 5000 where x speakers can be sold at $p per each speaker. The cost to produce x speakers is given as C(x) = 150,000 + 30x, where both C(x) and p are represented in dollars ($). - find the profit function and the marginal profit and interpret the quantity P'(4500) - find the marginal cost and interpret the quantity C'(3000) - find the revenue function and the marginal revenue and interpret the quantity R'(3000)Suppose that the market demand curve of food delivery service in city A is given by P = 100 − Q, where P is the price and Q is the quantity. Currently there is only one firm. The incumbent’s cost function is given by TC = 40q, where q is the quantity provided by the incumbent. Suppose that there’s a potential entrant with cost function TC = 40qe + 100, where qe is the quantity provided by the entrant. The 100 is the sunk cost for developing the delivery system that is paid upon entering the market. a. If the entrant observes the incumbent providing qi units of service and expects this level to be maintained, what output will the entrant produce? b. At what price will the incumbent sell this output to keep the entrant out of the market?
- A Los Angeles firm uses a single input to produce a recreational commodity according to a production function f(x)=4x1/2, where x is the number of units of input. The price of the commodity is $100 per unit, and the input cost is $50 per unit. The fixed costs are zero. A: Write down the firm’s profit function. C:Find the profit maximizing amounts of input and output. What is the maximum profit? C:Suppose that the firm is taxed at $20 per unit of its output (note it is a quantity tax) and the price of its input is subsidized by $10 per unit. What is the new input and output levels? What is the new maximal profit?Suppose the profit maximizing firm sells the same good in two individual markets that it is able to keep separate. Since the price elasticity of demand is different in each market, the firm recognizes that rather than charge all customers the same price, it can increase profits by charging different prices in each of the two markets. The demand equations for each market are shown below: Market 1 P=25-2Q Demand The firm's Total Cost Function is: TC=5Q a) What is the optimal output in Market 1? b) What price will be charged in Market 1? Market 2 P=15-Q c) what is the optimal output in market d) what price will be charged in market e) what is the firm's total profit f ) illustrate your answerThe marginal profit function of a firm (profit (Π), point (Q) rate change depending on quantity) is MΠ = Π ^ '= dΠ / dQ = -2Q + 120. The fixed costs of the firm produced by the company are 1000 TL. In addition, the company is known to sell the goods it produces for 200 TL. Accordingly, answer the following questions.a) Find the firm's profit function.b) Find the cost function of the firm.
- You own a road resurfacing business called Rockit Asphalting services located in Kingston. You are the only reservicing business in Southern Tasmania. Therefore, you have a local monopoly. Your experience running the company for many years has taught you that market demand for your service can be described by the demand function: p = 20 − q. The cost function is c = q2. Therefore, marginal cost equals 2q. Quantity refers to square metre of road resurfacing. Note the Q denotes aggregate market demand and q denotes your production. Of course, if you are the only supplier than q = Q. Compute profit maximising price and output. Compute profits. The monopoly profit that you have been earning has attracted attention from another firm that will set up operations in Southern Tasmania and compete for market share. You are concerned with losing market share and profit. So, you offer the potential entrant the following deal. Both firms agree to maximise industry profits (joint…A production process varies only with raw materials, as all other inputs are fixed.The cost of a shipment of 8kg of raw materials is fixed at $85.It takes 5kg of raw materials to create one item of output, Q.The marginal revenue for this process is expressed by the equation: MR = -Q^2 + 52Q− 576.Determine the optimal amount of raw materials to be utilized in this production process.The average avoidable cost for a fringe firm is AAC(q) = 20/q +5q. The marginal cost function for a fringe firm is MC = 10q. There are 10 fringe firms. The marginal cost of the dominant firm is 2 and the demand function is Q = 100 − P. What is the supply function of the fringe? What is p0, the minimum price at which the fringe will supply? What is the residual demand function for the dominant firm? What is the profit-maximizing price of the dominant firm? Compare monopoly profits to the profits of the dominant firm. Which market structure is socially preferable, dominant firm or monopoly? Why?
- Suppose both cooperatives are price-takers; with PG=12 and PF =10 being the market prices of gold and fish respectively. The cost of producing G units of gold is cg(G,x)=G2+(x−4)2; where x is the quantity of mercury effluent discharged into the dam. The cost of producing F units of fish is cF(F,x)= F2 + xF ; where cF(F,x) is an increasing function of x. a) Determine the profit maximizing level of gold output, profit and level of mercury effluent discharged into the dam. Comment and explain your results. b) What is the fishing cooperative’s profit maximizing level of fish output and profit? Explain your results. c) Suppose the two cooperatives were merged to operate as a single firm; determine the socially optimal level of gold and fish output, mercury effluent and profit. Explain, comment on and contrast your results with those obtained in a and b above. d) Suppose property rights to the dam water are created and assigned to the fishing cooperative. Does this induce efficiency and…When economists talk about a barrier to entry, they are referring to a.the downward-sloping portion of the long-run average total cost curve. b.a factor that makes it difficult for potential competitors to enter a market. c.the opportunity cost of equity capital that is incurred by a firm producing at minimum total cost. d.the declining output experienced as additional units of a variable input are used with a given amount of a fixed input.The market demand for Gucci bags is given by the function P = 75 - 1.5Q. P is price per bag, and Q is output per time period. The market supply is given as P = 25 + 0.50Q. A typical competitive firm that markets this type of bag has a marginal cost of production of MC = 2.5 + 10q. a) Calculate the market equilibrium price for the bags as well as the output rate in the market. b) Calculate how much the typical firm will produce per time period at the equilibrium price. c) If all firms had the same cost structure, how many firms would compete at the equilibrium price computed in (a) above?
