e now assume the firm producing a steel bar is under monopolistic competition. When the price of the steel bar is $ 30,000, the quantity demanded is 8 metric tons, a 100% change in the price would change the quantity demanded by 25%. The firms fixed cost is $45,000.

We now assume the firm producing a steel bar is under monopolistic competition. When the price of the steel bar is $ 30,000, the quantity demanded is 8 metric tons, a 100% change in the price would change the quantity demanded by 25%. The firms fixed cost is $45,000. Its variable cost in thousands at each level of production are 45, 85, 120, 150, 185, 225, 270, 325, 390, and 465. 1. At what production output should the firm produce in the long run? 2. At what price should the firm sell its product in the long run?
A friend has just started up her own business. Her firm asks you how much to charge for her product to maximize profits. The demand schedule for it is given by the first two columns in the table below; its total costs are given in the third column. For each level of output, you can calculate total revenue, marginal revenue, average cost, and marginal cost. The profit-maximizing level of output can be found at the point where TR - TC is greatest, or where MR = MC, (or the last quantity where MR is still greater than MC.) What is the profit-maximizing level of output for her product? 40 How much will she earn in profits? 80 Price Quantity TC TR? MR? MC? $25.00 0 $130 $24.00 10 $275 $23.00 20 $435 $22.50 30 $610 $22.00 40 $800 $21.60 50 $1,005 $21.20 60 $1,225
A textbook publisher is in monopolistic competition. If the firm spends nothing on advertising, it can sell no books at $100 a book, but for each $10 cut in price, the quantity of books it can sell increases by 20 books a day. The firm's total fixed cost is $2,400 a day. Its average variable cost and marginal cost is a constant $20 per book. If the firm spends $1,200 a day on advertising, it can increase the quantity of books sold at each price by 50 percent. Compared to the situation if it does not advertise, if the firm advertises,the profit-maximizing price: A)falls by $10. B)rises by $5. C)rises by $10. D)does not change.
Economics A textbook publisher finds himself in monopolistic competition. This company cannot sell books at a price of $ 100 pesos per book. But for each decrease of $ 10 pesos that he makes in the price, the number of books he manages to sell increases by 20 daily books. The fixed cost of the company is $ 2,400 pesos per day. The average variable cost and the marginal cost of the company is constant at $ 20 pesos per book. If the business spends $ 1,200 a day on advertising, it can increase the number of books sold at each price by 50%. What is the price that maximizes the profits of the company when advertising is used? $ 60 $ 70 $ 50 $ 40
Suppose that you are a manager for a firm like EBC Brakes, which manufactures brakes for automobiles and motorcycles. Your company has two plants, one in the United States and the other in the United Kingdom. The following tables include estimated demand and marginal revenue for your brakes, along with the marginal costs at the two factories. what quantity and price maximize your firms profit? What is the profit – maximizing number of brakes produced in the U.S. plant? In the U.K. plant? Quantity Demanded (brakes per hour) Price (dollars per brake) Quantity Produced in the U.K. plant (brakes per hour) Quantity Produced in the U.S. (brakes per hour) Total Quantity Produced Marginal Cost (dollars per brake) Marginal Revenue (dollars per brake) 104 196 47 42 89 66 92 105 195 48 44 92 68 90 106 194 49 46 95 70 88 107 193 50 48 98 72 86 108 192 51 50 101 74 84 109 191 52 52 104…
You are managing a firm with market power, and you think the price elasticity of demand for your product is between 1.3 and 1.5. You estimate that your marginal cost is between $55 and $70. The price that you should set would range between $ and $. (Round your answers to two decimal places.) If you refine your estimate of the marginal cost to $80, the price you should set would now range between $ and $ (Round your answers to two decimal places.)
MelCo’s Xamoff The global pharmaceuticals giant, MelCo, has had great success with Xamoff, and over-thecounter medicine that reduces exam-related anxiety. A patent currently protects Xamoff from competition, although rumors persist that similar products are in development. Two years ago, MelCo sold 25 million units for a price of $10 for a package of ten. Last year it raised the price to $11, and sales fell to 22 million units. Finally, a financial analyst estimates the cost of production at $2 per package. (a) Estimate the elasticity of demand for this product at $10. Is this price too high or too low? (b) Estimate the elasticity of demand for this product at $11. Is this price too high or too low? (c) Based on your answers to (a) and (b), what can we say about MelCo’s profit-maximizing price?
Exercise A.4. A company operating in a market of monopolistic competition has an inverse demand curve for its product: P=315-3q, where q is the number of units produced of the good and P its price. The total cost of production of this company is given by: TC(q)=q²+75q+4000. a) To maximize profits, how many units of the good should you sell? b) What price should I charge? (c) What benefits would it reap? (d) Given the above information, how much would you have to reduce fixed costs for longterm equilibrium to occur? Represent graphically
The diagram above represents a monopolistically competitive firm. Answer the questions below. Is this firm operating in the short-run or long-run? How do you know? Calculate this firm’s accounting profit. From the diagram, what is the productively efficient output for this firm? From the diagram, economies of scale are maximized at which output level? Explain. From the diagram, what is the allocatively efficient output for this firm? Explain.
You are the manager of the local movie theatre in a small town. Running a movie has a fixed cost of $2,000, but selling an extra ticket (i.e. accommodating an extra viewer) has zero marginal cost. Below are the demand schedules for your two types of customers: Price $ Adults Teens and Seniors 10 50 9 100 8 200 7 200 50 6 300 100 5 350 150 4 400 200 3 400 300 400 300 1 400 300 If you are to charge a single price (i.e., if price discrimination is prohibited), what price would you set for a ticket to maximize profit? How much profit do you make? Price = $ Profit = $ If you were allowed to price-discriminate, what price would you charge for an adult ticket? For senior/teen ticket? How much profit do you make? Price for adults = $ Price for seniors/teens= $ Profit = $
Suppose that Spacely Sprockets' marginal cost of a jacket is a constant $150 and the total fixed cost at one of its stores is $3,000 a day. This particular store seils 40 jackets a day, which is its profit-maximizing number of jackets. The nearby stores begin to advertise their jackets. The Spacely Sprockets store now spends $1,500 a day advertising its jackets, and its profit-maximizing number of jackets sold jumps to 50 a day. What happens to the price of a Spacely Sprockets' jacket, Spacely Sprockets' markup, and Spacely Sprockets' economic profit?
What will be the economic profit or loss for this monopolistically competitive firm at the profit-maximizing level of output?
